EXHIBITION MEETINGj 1949 
Seeds of Epilobium. adenucaiilon Hausskn. showing peculiar chestnut- 
coloured, pellucid api)endage below the jiappus, by G. M. Ash. 
Specimen of Aitislnckia from Fame fslands, by Mrs P. R. Farquhar- 
son. 
Salicornia Specimens, by Miss M. M. Whiting. 
These fresh specimens of Salicornia were collected on the edges 
of the marsh, east side, at Blythburgh Bridge, Suffolk, on the 
south side of the River Blyth, about five miles from the coast 
at South wold. They are of interest because, owing to repeated 
breaks in the river wall, large areas become flooded at every 
tide, and the salty marsh flora is coming much further inland 
than was the case a few years ago. The place of collection was 
less than five minutes walk from the village inn. 
Specimens of Amaranfhvs, by Mrs A. N. Gibby. 
Aviaranthvs species shown were all collected on waste ground 
in different parts of Paris. These were Amarantlius Blituin L., 
A. deflexus L., A. retroflexus L., A. hlitoides Wats, (upright 
and prostrate forms), A. Bouclwni Thell. 
AJnus incana, A. glutinosa and the hybrid between them from a 
wood near Horley, Surrey, by J. P. M. Brenan. 
Ahnis incana (L.) Aloench, an Eurasian species extending to 
North America, is well known as an established introduction in 
Britain. In August 1949, in Langshott Wood, Horley, Surrey, 
v.-c. 17, I observed A. mcana, A. glvtinosa (L.) Gaertn., and 
numerous trees most convincingly intermediate between them ; 
specimens of the two species and the hybrid were on show. This 
hybrid, well-known on the Continent, does not appear to have 
been previously noticed in Britain. A more detailed note on its 
nomenclature and characters is being pi-epared for ])ublication 
in Watsonia. 
Alisma gramineum C. C. Gmel, by R. C. Burges. 
The above plant grows in fair quantity round the western edge 
of Westwood Pool near Droitwich. It was in good flower at 
about 10.30 a.m. on July 22nd of this year, and growing in 
about 12 to 18 inches of water. In this stage there are two dis- 
tinct t 3 "pes of leaves, the submerged ones are soft and flaccid 
whilst these that appear above the water are stiffer and ter- 
minate in a lanceolate tip. 
The flowers are uniformly smaller than A. Blantago-aquatica 
and are always white. 
As the pool dries up, the plant is left completely exposed on 
the mud, and the grassy submerged leaves wither away leaving 
the stiff lanceolate leaves. 
Although it will grow amongst rushes it obviously prefers 
open mud, with Elutine Ilydropiper and a few plants of Limo- 
sella.
