124 Nuytsia Vol. 12, No. 1 (1998)

The probability of the genus being polyphyletic without the inclusion of Bororel/a from New

Caledonia was indicated by Weston el a/. ( 1984), and an investigation by me ofpetal venation and seed

morphology, characters which were not included in that study, could strengthen the proposal However,

Hartley (1995) doubts this close relationship and supports the argument for retaining ,oronella as a

distinct genus with details from a study of the articulation in the branchlets and of the shape of the

embryonic cotyledons. Ifthe close relationship ofBororla to Boronellaweretobe accaptedthen floral

and seed characters suggest that the latter is more closely related to sect. Boloria than that seation is

to anyofthe other sections in the genus. Logically therefor e Boronella shortld either be made a section

of Boronia or the sections ofBororla should be raised to generic level. In spite ofthese lese ations

Duretto and I have decided for the "Flora of Australia" to retain the genus with its traditional

circumscriDtion, while BoronellQ is assumed to be genedcally distinct,

As is noted above, the recognition ofthe infrageneric taxa within Boronia,while based largely on

floral morphology, is strongly suppofied by seed morphology The opportunity is therefore taken to

describe the seed types that have been observed in representative taxa of Westem Australian species

of Boronia.

Seed terminology in the Boronieae

sclerotesta. The hard, thick, and brittle portion ofthe testa. lt is always black in colour and is either

smooth or variably corrugate.

Outer testa. That portion ofthe testa outside the sclerotesta. It is membranous, papery, coriaceous.

or brittle. It may be smooth, or it may follow corrugations plesent on the sclelotesta, oI it may have

conugations that are independent of the sclerotesta.

Micropyle. This is minute and circular or rarely narrowly elliptic. It is always positioned ontheuppel

adarial margin ofthe seed.

Hilum. T\e scar formed by the dehiscenceofthe funicle oraril'. Itis always inthe central adaxial alea

ofthe seed and it varies in shape from linear to circular. In Boronie sect. Bororra it is sunken between

lateral lip-like raised portions ofthe outer integument and is here referred to as labiose.

Raphe. The v asc,,rlar strand and associated tissue that pass from the base ofthe hilum to the chalaza.

It varies from being shrivelled and insignificant to large and fleshy

Raphe cover. The tissue that folms a coverto the raphe. It is continuous with and usually has the same

texture as the outer testa and tlterefore varies from being membranous to brittle

Chalazal aperture. The circular hole in the sclerotestathrough which the raphe passes into the chalaza.

It is positioned beneath the raphe, either at the base ofthe seed or at its lower adaxial margin.

Hilqr strancls. In some generathe seed possesses a cream- coloured ligament-like tissue on its adaxial

surface. This tissue has the appearance ofa strand; it surrounds the hilum and extends, as a single thread,

to the raDhe. The strand is here called the hilar strand. Itis shed on orshofily after the discharge ofthe

seed. Hilar strands are found in the seeds ofChorilaenq, P hebqliumsect. Gonioclados, Rhadinotharnnus,

leaves nanowly to broadly obovate, 7-12 mm long, rounded to obtuse -Flowers predominantly

axillary with I or2 pairs ofbracteoles. Sepafu ovate, acuminate,2-3 mm long. Pelal,r glabrous outside,

minutely subapically apiculate.

Dislribriion. Occurs over the entire range ofthe subspecies.

Noles. The variant from near A lbany with broadly obovate leaves coffesponds to the type of B. crenulata

while the variant from near Bremer Bay witlt larrowly obovate leaves corresponds to the type of

B. \)imined var. gracilis.

The variant found nofih-west ofthe stirling Range and towards the Darling Range is sometimes

puberulous all over; it has narrow leaves and naffowly triangular to triangular sepals. This valialt is

somewhat intermediate in morphology between subsp crcnulatq ar\d s\bsp. vimineq.

Over most of its distribution the branches of this vadety are puberulous but in the Pembedon-

Walpole area they are pilose which suggests intergmdation with subsp. prir5escens.

Conseryation status. Known from one small area offorest which iS subject to mining and therefore

probably places the species under threat. A Priority One classification may be appropriate

Etymolog,,. The specific epithet, humiJusa, is aLatin word meaning spread-out over the ground and

refers to the low-growing habit ofthe plant.

NoleJ. The relationships ofthis species are uncertain. It does not agree with othel membels of sect.

Boronia sincethepetals lack an apiculum andhave only one main v€in, while the seed lacks an adaxial

groove. In typical members ofsect. Bororunthe petals have several medial nerves and have a subterminal

abaxial apiculum while the seed has a linear groove along the hilum. In inflorescence characters it

resembles B. sc4b,,a and B. ovata to which species it may possibly be most closely Ielated and fol which

reason it is here included in the series Boronla

Distribution. This species is fou[d near tl]e west coast of Westem Australia from Perth north to Shark

Bay, with one collection from near Leonora, c. 130 km noth ofKalgoorlie.

Notes. Boronia purdieana is vatiable in both vegetative and floral morphology, however, in anther

shape and lengththere are clearlytwo groups. There is a short-anther plant, which is referedto subsp.

purclieana, and a long-anther plant, which is refeffedto snbsp. calcicola. The plant that is found near

Leonora has shorl anthers but its habitat is very different flom that of the type locality of subsp.

purdieana.

Distribution. Foundfrom nearGnangara (c.20 kll north ofPerth) north to Coorow with a 1901 collection

from near Busselton; recently a sizeable population was discovered near Leonora

Habitat. Sal(ly seasonally waterlogged soil in Bair,tsra woodland; however, the one collection from

near Leonora was found growing on a shale and diorite hillside.

Noles. Diels, in his original description, records that this plant was sold in Perth as an ornamental due

to its fragrant flowers.

Distibution. Found on the south coast of Western Australia at Cape Le Gralrd and on the neighbouring

islands of the Recherche Archipelago.

Hqbitqt. Growing among granite rocks.

Conseryation stcttus. Altholrgh this subspecies is fbund in only a small area it does occur in a nationalpark and therefore is not under threat. A Priority Two classification would be appropriate.

Etynologt. The subspecific epithet alludes to the attenuate (Latitl attenuatus) shape ofthe sepals.

Noler. At Cape Le Grand and on some ofthe islands ofthe Recherche Archipelago is found the variant

with congested inflorescences while at Thistle Cove, c. 6 krn east ofCape Le Grand, and in Cape Arid

National Park is found a variant with slender peduncles and pedicels.

This subspecies is of particular interest because it liequently has ahernate leaves and 5-merous

flowers; for these reasons it has somgtimes been assumed to be a species of Eriostemon

Distribution and halrltat. Found in the extreme south-west of Western Australia between Soott River

and Walpole. Grows in seasonally swampy heaths.

ConserNation status. Although this species is known from a relatively small area some ofthe populations

are in a national park. A Priority Thr€e code is therefore probably appropriate.

Etynology. The Latin word aircepJ means two-edged and in this case refers to the shape ofthe stem

Notes. Baronia qnceps is evidently closely related to B. /.rsligiatq andto B. spathalala; it differs from

both in having flattened ancipitous upper intemodes and apparently ir lacking a lignotuber.

Notes. Boronia dicholona is readily recognized by the glandular aculeate proceSses that are found on

the pedicels and to a lesser extent the peduncles and terminal portions ofthe stems. The leaves vary

from being obovate (c. 2 cm long) towards the base ofthe stem to slendel-tefete (c. 4 cm long) belorv

the inflorescence. The stem s are slender and the internodes vely long, the upper ones up to 12 cm long.

The type of B. integrifdia differs from material otherwise included in B dichotoma in having

relatively srnall glandular aculeate processes; it also differs in all the leaves being ell iptic and 6- 12 mm

long with the upper internodes only slightly exceeding them. The district in which the type is stated to

have been collected is 5 0- 100 km east ofany other record for B. dichotoma. Boron i.t integri-foliq could

be recognized as a distinct taxon, but it is possible that the type is a hybrid between B. dicholom.l and

B. Jastigiatd or betwee.I. B. dichotona and another member of Boronia ser ' Pedunculatae.

Distribution. Known only from the Scott River area, extreme south-west of Western Australia

Habitqt. Growirlgin seasonally wet heath.

Conservdtion stcttus. Classified as Declared Rare Flora, it is only known from a few sites over a small

area.

Etymolog). The Latin word exilts, meaning slender andweak, refers to the slender stems ofthis species.

Notes. This species is similar to Boron iq juncea, particularly to the subsp. laniflora; it differs most

obviously from that species inhaving strongly ciliate staminal filaments (inB.jarceathey are glabrous).

Boronia fastigiata Bartl. in Lehm., Pl. Preiss. I : 167 ( 1844). Zype; "In locis h ieme inundatis districtus

Plantagenet" lAlbany area], Western Australia, November 1840, L Preiss 2028 (lecto LD;.

isolecto: MEL), lectotype here chosen.

Distribution. Foundin south-west Western Australia from Perth to the south coast as far east as Albany.

Noles. Two subspecies are recognized.

Branchlets terete subsp. fastigiata

Branchlets with four very naffow glandular undulate wings subsp. tenuior

Boronia fastigiata Bartl. subsp. fastigiata

Brqnchlets tercte. Leaves narrowly lo broadly elliptic or obovate, 1-2(3) cm long, entire or almost

so. crlaeJmostly terminal to longbranches. Pedicels oflateralflowers ofcyme with a pairofextremely

minutely bracteoles or incipient buds at base.

Distribution. Found in south-west Western Australia from Perth to Collie and from there south-east

to Kojonup and Albany.

Habitctt. Collectors' notes indicate that it occurs in latedtic gravel

Noles. This subspecies is similar in its inflorescence and in its floral characters to B. harkeriana from

New South Wales.

The type of B. fqstigiala is ofa variant with leaves crowded (the intemodes c. 4 mm long), broadly

elliptic, 6-9 mm long, and sermte. It was collected in the Plantagenet county which encompasses the area

aroundAlbany, Denmark, andthe stirling Range, The specimen matches material collectedbetween slab

HutCreekand cranbrookby capt. A. Dorrien Smith in 1910 and n ear Koj onup by w.E. Blackallin 1933.

All recent collections ofsubsp./aslrgrala have come from between Perth and collie suggesting that it

no longer occurs fufiher south. Some collections from neal Albany are intermediate between this

subspecies and B. denticulata.

No/es. In the strict sense this subspecies is only known from a few collections all from the same locality

about2T km north ofBunbury. Its distribution is therefore evidently quite separate from that ofthe other

subspecies. However, material o f B. juncea frontthePembedon to Donneybrook area, that is here referred

to svbsp. minimq, is somewhat intermediate in morphology between the types ofsubsp.jarcea and

s}bsp. tninima.

Additional specimen examined. WESTERN AUSTRALIA: 13 km SW of90 Mile Tank, Frank HannNational Park, 1 1 Nov. 197 9, K. Newbey 64?7 (PERTH).

D istribution. This species has only been recorded fron Frank Hann National Park, c. 90 km nofth-east

of Lake King township, Western Austrulia.

Hqbitat. Fol'lmd, in Eucalyptus salmonophloia open woodland on well-drained clayey sand.

Consemqtion status. This species is known from only one locality where, according to the collector(K.R. Newbey), it is very common. An attempt was m ade in 1996 to re-collect this species but it could

not be found, probably due to a fire having passed through the area the previous year. A Priority Two

classification with priority for survey would probably be appropriate for this species.

Etynologt. The specific epithet is derived from the Greekwords coryne, a c\tb, andp hyllon, aleaf ,withreference to the shape ofthe leaves.

Notes. Boroniq corynophylla is distinctive because ofthe shape ofits leaves and the exfoliating cuticle

on its branches which gives the plant a glaucous appearance. The valvate aestivation of tl'le petals is

interesting since the sepals are imbricate. This sjtuation is also found in B. a/gida, a species ofsouth-

eastem Australia, and with which -8. corynoplTylla is probably most closely related (M. Duretto, pers.

com.). Seed is required to positively detemine its sectional position.

Etymotogt. The epithet is derived fromthe latinized G teekwof ds clcctntho-, spiny, and c/adas, abranch.

ly'oles. This species is most closely relate d.to B. coerulescens. The presence ofalternate leaves, although

not unique, is unusual in the genus as are the spinescent branchlets. Itis similar in appearanceto some
