help sort and pack NOSSA equipment. Time will also
be given to planning for the spring flower show.
Weeding at Brentwood Cemetery Saturday 7th June
10am
A joint working bee at
Brentwood Cemetery has
been organized by Natural
Resources Management
(NRM) Northern and York
Group and the Threatened
Plant Action Group
(TPAG). This small
cemetery is approximately
8 km south-east of the
Hardwicke Bay along
Cutline Road, on Yorke
Peninsula. As weed invasion is a serious threat to the
nationally endangered Arachnorchis intuta or ghost
orchid which is located at this site, this is a necessary
task. Anyone is invited to join this weeding project but
as the Friends of Brentwood Cemetery will be
providing lunch it is requested that anyone intending to
participate needs to notify NRM Team Leader,
Deborah Furbank. Phone (08) 8854 3208 or Mobile

Changes to Field Trip Procedures
From time to time field trips may need to be cancelled
for various reasons beyond our control. In such
circumstances folk intending to participate need to be
informed and to that end the committee has decided to
require bookings for field trips.
The preferred method is to book through:
[email protected] OR if that is not
convenient phone Rosalie at 8294 8014.
It also pays to check the NOSSA website to check the
status of any field trip. http://nossa.org.au/events/
NOTE: Following recent rains the field trip to Mt Billy
will now take place.
Vale Park Our Patch (VPOP) Website
Following last month’s report on this wonderful
project, readers were encouraged to find out more
about VPOP through their web site. Unfortunately for
those who receive a printed version of the journal the
website was virtually unreadable for which we offer
our humble apologies.

SUMMARY OF APRIL MEETING
Lorraine Badger
The guest speaker for the night was Jason Tyndall, regional coordinator of
Natural Resource Management (NRM) which is hosted by the City of
Onkaparinga. His chosen topic, “Orchid Stories: Connecting children to
nature through orchids” proved to be a fascinating and thought provoking
story.
Finding ways to connect children with nature is more important today than
at any other time in history and Jason shared his passion for working with
children in various schools. In his talk he sought to demonstrate the ways
in which he imparts his message by using the powerful form of
storytelling. Accompanied by a photographic power point he shared how
he had used orchids, which he has found to be one of the most interesting
plants, to engage children.

FROM THE PRESIDENT
Robert Lawrence
I am honoured to be able to write my first article as
President of the Native Orchid Society of South
Australia Incorporated.
I would like to thank Geoff Borg who stepped into the
role of President two years ago and oversaw a time of
adjustment. During his term Bill Dear moved to
Western Australia and Cathy Houston was no longer
available to serve the Society. The contribution made
by each of them is sorely missed.
I would also like to thank John Bartram who stepped in
to the role of Secretary early in 2013 after I found it
necessary to leave the role. This enabled the Society to
continue to function. I am pleased to welcome
Michael Clark as Minutes Secretary for the committee
meetings. Bob Gunn has kindly commenced taking
minutes of the general meetings, thus helping to share
the load.
In the later part of the year 2013 Helen Lawrence
started as Assistant Editor and produced an updated
format. John and Lorraine Badger commenced in the
role of Editor from the start of this year. David Hirst
has done a wonderful job as Editor for eleven years
and has served the Society well throughout this period.
He has given the new editorial team an example to
emulate.
Looking ahead, the Society faces a number of
challenges. The number of growers benching plants
and contributing to the annual Spring Show is
dwindling and there appears to be no new growers. It
has been exciting to learn about Trevor Gerrard in his
role as Education Officer of the Orchid Club of South
Australia with the Orchids in Schools Program. We
hope that this will contribute to a new generation of
orchid growers and that
some will take a particular
interest in Australian
orchids.
We also want to make sure
the range of activities and
publications meet the
expectation of all of our
members, many of whom
receive the Journal without
attending general meetings
or field trips. We hope we provide a range of materials
that readers find interesting.
New and exciting opportunities could be started in the
next couple of years. These include a web-based
interactive orchid identification key and
commencement of directed data collection for citizen
science projects on topics such as the distribution of
orchids and the timing of flowering.
This is just a brief snapshot of issues. In writing these
I am mindful of contributions of particular members
that I have not mentioned above; these continue to be
important and I certainly want those who contribute to
know that they are valued. Members are more than
welcome to bring to the attention of the Management
Committee any issues that should be addressed or
would make the Society more relevant to its members,
or if we are doing things well that should not be
changed.
NOSSA @ AUSTRALIAN PLANT SOCIETY AUTUMN SHOW
NOSSA members recently promoted the society at the APS Autumn Sale with a
display of native orchid material even though there were no orchids for sale on this
occasion. Time was taken on the previous to set up the area in such a manner as to
attract the show goers. Gordon Ninnes’ expertise combined with the assistance of
Jan Adams and Rosalie Lawrence meant that people were certainly drawn to the
area on the show days. A favourite attraction was the society’s orchid diorama
created with replica orchids cleverly formed from paper by former member Thelma
O’Neill. Thanks go to all who helped out over the two days.

WINNING PICTURE FOR APRIL 2014
ROSALIE LAWRENCE
With the range of photographs
submitted it is always difficult to guess
which picture is likely to be the winner
but somehow this month’s winning
photograph by Lorraine Badger was not
surprising. With a common name of
Queen Orchid, Thelymitra crinita is
aptly named for the flower has a quiet
regal air of elegance and delicacy that
would appeal to many people. Other
entries were: Jane Higg’s Eriochilus
(2nd), John Badger’s Corunastylis sp
Adelaide Hills (equal 3rd), Helen
Lawrence’s Jonesiopsis capillata
(equal 3rd), David Hirst’s Pterostylis
laxa, David Mangelsdorf’s Acianthus
pusillus, Pauline Meyers’ Caladenia
crebra and Marg Paech’s Calochilus
robertsonii,
T crinita is a common Western
Australian orchid that can be found
from Perth around to Albany with a
disjunct area near Esperance. Back in
1839, it was one of 60 orchids named
by John Lindley in ‘Appendix to the
first twenty-three volumes of Edwards’
Botanical Register together with A
Sketch of the Vegetation of the Swan
River Colony’. Though the register is
written in English the species
description is in Latin, reproduced here
for all those Latin buffs –
(214) helymitra [sic] crinita; folio
radicali oblongo apiculato glabro,
raceme cylindraceo, floribus purpureis,
cuculli laciniis lateralibus barbatis
unguiculatis intermediâ fornicatâ
emarginatâ dorso glanduloso-villosâ.
On a recent visit to the Herbarium, Michelle Waycott, Chief Botanist, explained that there is a strict botanical standard for describing a species. You may be pleased to know that at the 18th International Botanical Congress in Melbourne, Australia in July 2011, it was
determined that from the 1st January 2012 it was no
longer mandatory for descriptions to be in Latin only. English can now be used.
For anyone wishing to enter the monthly photographic
competition images can be:
1. emailed to [email protected] or
2. mailed to PO Box 565, Unley SA (5061) or
3. brought to the meeting on the night

ORCHIDOLOGOGIST JOHN LINDLEY (1799-1865)
R OSALIE LAW R ENC E
John Lindley (1799 - 1865), who named the above mentioned Thelymitra crinita, was one of the world’s earliest orchidologists and has been described as the Father of Modern Orchidology (Pridgeon, p.1). Having
no formal university education his career began under Sir Joseph Banks as assistant-librarian. He eventually rose to Professor of Botany, University College, London, amongst many other numerous official duties and public activities. It was the result of Lindley’s work and involvement with a group of other like-minded men that Kew Garden was saved from
destruction and Corn Tax was repealed at the time of the great Irish potato famine.
Although orchids were not his only area of interest
they were his passion and the common name ‘orchid’ was introduced by him in 1845. Lindley became involved with the naming of orchids at a time when the western world was discovering the wealth of the orchid world and his subsequent work on orchids was prodigious. He personally examined and named thousands of species specimens, with one author
stating that Lindley named over 6,000 orchid species, establishing over 120 genera. Notably he wrote three major orchid works Genera and Species of Orchidaceous Plants (1830-1840), Sertum orchidaceum (1838), and Folia orchidacea (1852-1855). He also wrote for the general public and one delightfully readable textbook was Ladies’ Botany or A
Familiar Introduction to the Study of the Natural System of Botany Volume I and II (1834 – 1837).
Though not referring specifically to South Australia, he lamented “that there are still, however, many species from the East and North Coast (of Australia), with which he has no acquaintance” [sic]. As far as I can
determine none of our endemic orchids were named by him.

REPORT ON NOSSA OUTING WE DID NOT HAVE
LEO DAVIS
Our quest for Leporella fimbriata at
Scott Conservation Park was pencilled
into my Planner so indelibly that I
headed off on my own searches, that
day and on others, and I report on
those forays.
I headed for Scott Creek C.P. first (no,
even though for some years I didn’t
realise Scott and Scott Creek were
NOT the same place, I do know now)
in my usual dream state, so missed the
Stirling turnoff, and settled on
Meadows Flat instead. The Midge
Orchid (Corunastylis sp.) plants John
Badger had led us to on the last visit
were well past flowering, now
pumping up their ovaries, and there
was not a sign of Parson’s Bands
(Eriochilus sp.)
On then to the always reliable Knott Hill NFR
where the results were the same, with the addition
of a single double flowered and a single triple
flowered specimen of the Fringed Hare Orchid (L.
fimbriata). You know what an odd bod I am and
how easily pleased, so you’ll not be surprised that
the day’s highlight was finding many leaves of the
Small Flying Duck, (Paracaleana minor), to 68 x
2 mm, and its large relative, Caleana major, to 42
x 5 mm. These very late flowering species are
always among the first out of the blocks.
I had high hopes for Scott Creek C.P. because Bob
Bates had shown us L. fimbriata growing in an
unexpected location, among Oyster Bay Pines
(Callitris rhomboidea) during our May 27, 2012
outing. More than 20 flowering plants were found
and many more in leaf only. Hopes were dashed
when I arrived on April 30, this year because a
fire, controlled or not, had gone through the area
recently. My plastic tags, on Thelymitra
benthamiana, T. carnea and Caladenia pusilla
sites, are now, let’s say, a lost cause. The Oyster
Bay Pines were gone. Down along the creek the
fire had either not taken or had been held at bay
and a few Parson’s Bands were in flower, Midge
Orchids were in fruit and Pterostylis pedunculata
were well in leaf.
Later the same day I went across to Mark Oliphant
CP and along the Waterfall Track found Parson’s
Bands in flower all along the track. Those few I’d
seen in flower back on March 24 were now in
fruit. There is a wide variation in prime flowering
time at the various locations.
There are clearly local populations of orchids.
Along about 300 or more metres of Waterfall
Track I saw hundreds of Parson’s Bands flowers,
in spasmodic and dense distributions, and I saw
just one double flowered spike. Along Moore’s
Road, at the top of Morialta C.P., throughout the
first half of April, I watched the Parson’s Bands
gradually come into flower and along a 200 m
stretch of fire track verges there were several areas
busy with plants and I found numerous double
flowers and in two spots found triples surrounded
by doubles. It’s all in the genes, I say.

2014 ORCHID SEASON
Robert Bates
After a very dry March and April in the Adelaide Hills
and most of coastal South Australia the wild orchids
were looking very sick due to water deficit and our
first ever autumn plague of flower thrips.
Our April field trip was cancelled and consideration
given to postponing the May excursion. Fortunately
heavy rain at the end of April turned the situation
around and orchid leaves began to show, right on time
indicating an above average orchid season.
Further north in the Gawler and Flinders, heavy rains
in February were of no benefit to orchids but good rain
in early April and early May set the scene for a bumper
orchid year on our desert fringes. Certainly autumn
orchids in the north have been impressive already,
especially in areas burnt by the Bangor Fire.
Editors’ Note: The year certainly has seen a slow start
to the orchid season. The following historic article
makes a good comparison with 2014 as well as
interesting reading.
FIELD TRIP TO HINDMARSH FALLS AND KNOTT HILL 25 4 1981
R.J. Markworth
Reprint from Native Orchard Society of South Australia Journal Vol. 5 No p.35-37
Adelaide's unusually long ‘Indian summer' provided a
really good turnout of members with a perfect autumn
day in which to enjoy our first field trip for 1981.
After some initial socializing involving a great deal of
chin-waging (an important aspect of the Society's
activities which excursions provide excellent
opportunities to indulge in), we walked from the
Hindmarsh Falls picnic area to view Pterostylis obtusa
in one of the few locations in South Australia where it
seems to grow.
The location accords remarkably well with Nicholls'
description of the plants ‘Eastern States' habitat, "…
most commonly or rocky timbered hill slopes - it may
be found plentifully among ferns and on mossy slopes
in sheltered forest areas”
In his delightful little book "South Australian Orchids"
(1911), Dr. R.S. Rogers made the following reference
to P. obtusa: "P. obtusa has quite a blunt tongue." …
obtusus (Latin) - blunt ..:... " This species is said to
have been found at Port Elliot. For many years 1
hunted it unsuccessfully, but two years ago I ran it to
earth in the Ravine de Casoars, in the unfrequented
west coast of Kangaroo Island. Since then I have
received specimens from Mount Muirhead "... between
Millicent and Mount Burr "collected by a school child
in the district."
In the Transactions of the Royal Society of South
Australia (1909), he records the original discovery
(attributed to his wife) as occurring, at the end of
September, 1908. He based his determination of the
species on half a dozen withered specimens which he
thought had probably, flowered in July and August.
It occurs to me that late September is a long time after
the usual flowering period of this plant (April and
May), in which; to see "withered specimens". The
Third Edition of J.N. Black's "Flora of South
Australia" (1978) does not record P. obtusa from
Kangaroo Island. I wonder; whether the good doctor
really saw the plant we know as P. obtusa, or perhaps
some other species.
Unlike our previous visit to this area in 1979, 1981 is
definitely not a vintage year for P. obtusa, having
probably been too dry. Although a number of plants
were flowering and some were in bud, many had
already wilted. They were not present in the numbers
seen in 1979. Other orchids recorded were Acianthus
exsertus in bud, and the basal rosettes of Pterostylis
spp. There was some discussion as to which particular
species the rosettes belonged to, but as P. pedunculata,
P nutans, and P. curva are known to grow here,
perhaps all were represented.
An interesting non-orchidaceous plant seen growing at
the side of the track was a Correa with greenish
flowers, probably Correa calycina.
Regrouping at the picnic area, we then travelled across
the top of the range to Knott Kill in Kuitpo Forest. The
views along the way, through wide valleys to the plains
and the sea beyond, were quite beautiful. However,
45
Journal of the Native Orchid Society of South Australia Inc. April 2014 Vol. 38 NO4
40
although a large part of the way was tree-lined and
through bush land, the greater part of the journey was
over unsealed roads, and tail-enders in the convoy
were more concerned with seeing through the dust than
looking at scenery.
Knott Hill is a favourite venue for members interested
in rare and uncommon species, and has been visited on
several previous occasions. \
This time, we found plenty of flowering specimens of
Leporella fimbriata, Prasophyllum rufum in smaller
numbers, and what must have been the last flowering
plants of Eriochilus cucullata for this season, while
basal leaves of Lyperanthus nigricans and Thelymitra
spp were recorded. Unlike 1979, however, a diligent
search failed to uncover basal leaves of Acianthus
caudatus, A. reniformis, Caleana major or Paracaleana
minor. The area is now somewhat over-grown making
the search difficult, but maybe the season has been just
too dry.
Bob Bates pointed out that since the Leporella is
pollinated by a male bull ant, and these insects only –
emerge under the right conditions of temperature and
humidity, the flower must remain open for an extended
period of time if pollination is to be effected. This is
fortunate for people like ourselves who like to seek
them out.
Probably the most conspicuous non-orchidaceous plant
flowering here was Correa reflexa, its red bell shaped
flowers being infinitely more visible than the Correa
sp. growing at Hindmarsh Falls.
All in all, we enjoyed quite a successful excursion on a
beautiful day, undertaken in an unhurried, even
leisurely fashion, which suited the balmy weather, and
seemed to suit the general inclination of most of the
members present.

A NOTE ON GREENHOOD TAXONOMY
LEO DAVIS
Bob Bates has contributed thoughtful, informative
articles to this Journal that present a strong case for the
use of a number of genera of Greenhood orchids.
These propositions seem soundly based to this amateur
field observer. His arguments, for example, that the
“Bearded or plumed greenhoods became
Plumatichilos, Shell orchids became Diplodium;
striated greenhoods became Bunochilus” just seem
good sense, (DNA and other evidence, etc., aside)
when we consider what clearly discernible
morphological differences we amateurs see in the field.
I have studied some of the published articles behind
the debate and submit my interpretive summary of the
latest published classification, as I understand it. This
places all Greenhoods into the single genus Pterostylis.
(Table below).
Janes and Duretto (2010) reject the division of the
Greenhood orchid genus Pterostylis into 16 genera by
Szlachetko (2001) and Jones and Clements (2002) and
instead propose a single Pterostylis genus comprising
two subgenera (Pterostylis and Oligochaetochilus)
within which they set up 10 Sections.
Janes et al (2010) “concluded that the generic concepts
proposed by Szlachetcho (2001) and Jones and
Clements (2002b) were questionable”.

I suggest that even if Janes and Durettos’
interpretations of literature and data are correct, that is
not sufficient reason not to consider a rational division
of the large and highly diverse genus Pterostylis. A
cursory glance at the table above suggests the
possibility of setting up at least two genera (Pterostylis
and Oligochaetochilus) or, alternatively, up to 10
genera (which, according to Janes et al, would spread
what I like to call Oligochaetochilus species across 5
different genera!). Both these possibilities would be
consistent with the DNA results reported by Janes et al
(2010).
But I’m surrendering. Out in the field, where nobody
knows, I’ll continue to seek out and identify
Bunochilus, Diplodium, Hymenochilus,
Oligochaetochilus, Plumatichilos, Urochilus, etc.,
plants but in public I’m going to be a Pterostylis man
all the time.

INCORRECT IDENTIFICATIONS
Rob Bates
DL Jones’ Native Orchids of Australia (2006) is an excellent book and is certainly my main reference on Australian
orchids. However, the following SA orchids have the wrong species shown in their illustrations
1. Petalochilus prolatus: page 40 shows a pink flowered Caladenia with tall labellum side lobes. True P.
prolatus as shown in Orchids of SA is always white flowered.
2. Corysanthes expansa: the image on page 171 is one of the many forms of C. despectans. For true C.
expansa see Orchids of SA.
3. Corunastylis tepperi: the image on page 189 is acceptable as C. tepperi, but as this species is based on
material from South Australia it would have been better to have chosen an image from SA.
4. Prasophyllum constrictum: is a mallee species so it is hardly useful to show an image of Prasophyllum
species Bushfires from near Mt Lofty (page 206) as an illustration of it. Similarly the image of P. pruinosum
on page 212 is hardly a good example of the species.
a. Prasophyllum fecundum R Bates: on page 218. The image used here is P. sp Enigma.
b. Prasophyllum calcicola R Bates on page 219 is a species based on South Australian material and
the WA image used is very different from P. calcicola in the true sense.
5. Microtis: the images used to illustrate SA and WA species are often way off the mark. M. familiaris R
Bates from WA for example is a species with the lateral sepals clasping the ovary which is not the case in the
image used on page 224. It is clearly M. brownii.
a. M. graniticola R Bates on page 225 is a species with a very large labellum whereas the image used
shows flowers with affinities to M. eremaea R Bates and nothing like graniticola.
b. Likewise with Microtis oblonga on the same page. This species, based on Victorian material, has a
long slender labellum nothing like that of the NSW specimen illustrated.
c. On page 227 the image of a woodland plant purported to be the waterhole species M. quadrata R
Bates is a very poor match.
I admit that Microtis is a difficult genus to work with, but poor images of the wrong species will not help
anyone to work out the genus.
6. Thelymitra images are much better, but I do have a problem with the use of a Tasmanian plant to illustrate
the SA species T. bracteata especially as the image on page 234 is nothing like the real T. bracteata.
7. Calochilus images are great but somewhat misleading on all SA forms. The concept of accepting C.
imberbis as a species but ignoring SA’s C. cupreus is mystifying. Also the use of an Adelaide Hills
woodland image of C. platychilus to illustrate C. robertsonii on page 262 when true C. robertsonii is a heath
land species based on plants from SW Victoria is not at all helpful.
8. Oligochaetochilus: images of South Australian species were most unimpressive especially O. ovata which
showed nothing of the species’ special features. Otherwise the Pterostylis in general are well done.
