F.XTlTTtTTION MEETINO, 1950 
EXKIBJTION MEETING, 1950 
An Exhibition Meeting was held in tlie Eoyal Horticultural Society s 
New Hall, Greycoat Street, Westminster, on Saturday, 25th November 
1950, from 3 to 6 p.m. The attendance was a record one, comprising 90 
members and 28 guests, a total of 118. Twenty-seven exhil)its were put 
up; of these 17 were herbarium specimens, 2 distribution maps, 3 manu- 
script and diagrams, 3 ])hotographs and 2 paintings. 
The following is a list of the exhibits, with, in most cases, notes sn]>- 
plied by the exhibitors. 
1. EXHIBITS OE INDIVIDUAL SPECIES. 
THE GENUS POLYG.\EA L. IN KENT. 
The County of Kent is interesting for its richness in this genus ; 
five out of the six British species occur in it, Pol/ygala nustrinca 
Crantz being now unknown in any other British county, having be- 
come extinct in Surrey. 
1. Distribution Maps of the five Kentish species were exhibited. 
Pulygala vulgaris L. is very common throughout the Chalk, 
except in Thanet, but rare elsewhere, though found in a few 
places in clayey grassland and on the Ragstone. P. serpyllifolin 
Hose is cojifined to acid soils, but on such soils is abundant on 
heathlands and woodland rides, etc. P. oxyptera auct. is con- 
fined to the Chalk and is somewhat rare, but an interesting con- 
centration of its localities on the eastern escarpment near the 
sea coast is noteworthy. This may be a climatically influenced 
distribution. P. austriaca Crantz is very rare and occurs in a 
few widely scattered localities in old chalk turf -across the centre 
of Kent, with a small local concentration east of Wye, where 
the plant also occurs in far greater numbers. 
P. calcarea F. Schultz has an interesting “double” distribu- 
tion. It occurs very plentifully in old grassland in mid and 
west Kent, usually with P. vulgaris L. (but does not follow this 
species on to relatively neu’ chalk hank turf and re-grassed 
arable land), hut it fades out east of Lenham, going no 
further east than Westwell. Then, eighteen miles to the east 
a form of it reappears in four or five localities about Dover, but 
it cannot be found between these points. This eastern form is 
different from the western one, as described below. 
Kentish material of 1\ vidgaris L. forms, P. calcarea E. 
Schultz forms, P. oxyptera auct. and P. austriaca Crantz was 
exhibited; also P. ccdcarea. E. Schnltz from Rutland. 
2. Some Interesting Forms of Polygala Species Observed in Kent. 
Polygala- vidgaris L. Besides the normal diffusely-branched 
form of this species with lanceolate-acute leaves and flowers 
which, when not pink or white, are purple-blue, there, occurs in 
eastern Kent a form which superficially resembles P. calcarea 
F. Schultz. Examples ■ of this were shown from Alkham and 
I'rom jiear Dover. The root-leaves are brownish-green as in 7k 
calcarea, and approximate in arrangement to a loose rosette.
