The size of the lake is yet another factor which influences the flora, and smaTI·a.reasof.productive water, Le., ponds often contain Fbtamogeton crispus (curled pondw~ed).

The plants common to most lakes of moderate nutrient content, that is those occupying the mlddle of the range of conditions, is

" }!yriophyllum alterni!lorum (alternate-flowered water-milfoil). Of the emergent species Carex vesicaria (bladder sedge) and Carex paniculata

"; (panicled sedge) are frequently found. But rather than possessing ~~' distinct indicator species of their own, lakes of intermediate

nutrient content generally have a somewhat impoverished version of the f'lora·of.hard-water lakes, the number of species diniinishing progress­ively-through the transition to soft-water lakes.

The 'only distinctive character of:'the soft-water lake is the presence of submerged rosette plants other than Littorella uniflora (shore-weed) (which is non'selective). The full complement of plants of this type includes Isoetes lacustris (quillwort), Lobelia dortmanne. (water lobelia), and less frequently Isoetes echinospora, and Subularia aquatic a (awlwort). Among ~5 such lakes Isoetes lacustris was present in 10 of them, Lobelia in 8, Isoetes echinospora in 5 and Subularia in 3. By a process of elimination' the flora of these lakes is numerically the smallest and although Carex rostratu i~ a ubiquitous sedge it takes on a dominant role in soft-water lakes where none of the other aquatic sedges survive. ~n similar mf<nner Equisetum fluviatile. (water horsetail) also comes,into predominance.

It is interesting to' see which species are the most widespread (non-selective) and for this purpose those species present at 20 or more lakes out of 50 lakes examined are listed below in order.

Of course, these results are only provisional and for greater

- page 5 -

accuracy a lerger number of lakes should be analysed and for every lake included a ,plant , list which'i5~complete is necessary. These two pre-requisites point to the way for the work still needed on this survey: quality, i.e. completeness of the plant lists, shciuld'not be sacrificed for quantity, i.e. number of lakes visited.'

.' On' 6th July six members explored the' swamps, and fens, bodering, this lake which is second only. to Bala Lake':in size of. the natural'lakes in Wales'. , The party ,worked along the northern ,shore first, seeing Butomus umbellatus (flowering rush), Rumex maritimus~ (golden dock),

and several pondweeds: Potamogeton crispus, P.perfoliatus, P.lu~ and P. berchtoldii. .After lunch the southern extremity of the lake was examined alld dense stands of' tall sedges'prov.ed most puzzling. Later determination of specimens showed that Carex acuta, C.aquatilis and C.elata were ,all present.

The main purpose of this meeting held on 27th July,was to examine the flora of two limestone areas in Denbighshire. The morning was spent,looking at,the vegetation of an olf limestone quarry, beech wood, and limestone outcrop just east of Loggerheads. ,Some attention was paid to the apomfcGic groups Alchemilla, Hieracium and Rubus and to the recognition of a number of species of Compositae whic usually prove difficult to identify_ Of the more. interesting species seen in

in C'ardiff" on 28th September~.2.§L

Twelve members and eleven visitors, m&inly teachers of biology in Cardiff and Glamorgan sc~ools, attended the morning session at 11 a.m. The session opened with a welcomong address by }krs. H.R.H.Vaughan, deputising for th~ Chairman, Dr. W.S.Lacey, who was in the United States. Mrs. Vaughan gave a summary of the past year's activities and remark(d on the encouraging increase in membership there had beer in Wales, adding that a continuation of this tren,d was very nn. ch hoped for.

'There followed three talks, two 01 which were illustrated by slides. Dr. B.Seddon (National Musetm of Wales) spoke about "Plants of the Welsh Lakes" in which 1.e described and illustrated the variety of water plants and the ~. pes of lakes found in Wales. Professor R.C.McLean (Emeritl:s Professor of Botany in the University·.of Wales) then gr/e hi:: "Reflections on Botany" in which he traced .thedevelopm(·.lt of· the Society and the changing emphasis in the sub ject in r( cent years. With tha publicationof··the· "Atlas of' th( Bri tj sh Flora ll now behind us he thought'that:.B.S.B.I. members coulC:turn their attention increasingly from plant di.strib\".cion io biological studies of individual species. Dr. J.P.SavidgE (University College of Wales, Aberysywyth) concluded the marring session with a talk on IIExperimental.studies :on the ·evolui.. ion. o~ .P1:ant:species" • He. illustrated differences between clcsely related species having ·differentdhI'omosome numbers :m.d ~.other,cases in which ... species ll'airs' 'se'parated ·mainly by ·thejr .disti~. ,distributions could be regarded as extrem,~ forms of a series showing continu­ous variation.'>' (:'

duriag the past year on possible future lines of activity_ Dr. M.Percival suggested that observations on floral biology and insect pollinators w uld be a very useful extension of activities. She also expressedthe'view tu at tie prDctice of.many schools in requiring pupils to make a collection of pressed specimens of wild flowersJias not a stimulus to t1 eir interest in botany. In addition the prac'tice was detrimenta.J..: to the local flora in its emphasis on the rare or unusual specimen. Othe'r .speakers agreed ·that specimens of rare .speciesfrom all. their well-known locall ties were a.1.readyrepresent.ed often in duplicate and triplicate, in 'the major herbaria and ,inconfrast re:presenta~ion

. and knowledge of, the .. more ,conrnon specie5was relatively lacking~ ' .. ))r. Seddon s'ugges"te'd that instead of 'me'relYrecording the .presence

of, a species at a giVen place';more attel,.~ion:,shoUldbe given :to its' biology J e.g. :t.im:e of' :flo;rierlng, "OD "to-recording. the ... aiti'tude of i"ts' occurrence' or the habitit of',theiplant, at 'each locality. Dr. Savidge referred ,to the' subject: of his talk which showed that variation within "a.
