Leersia oryzoides (L.) Sw. 13, W. Sussex; abundant in and on banks 
of ditches on Amberley Weald Brooks, Aug. 18th, 1947. This grass made 
a wonderful show along a considerable length of ditches on the Amber- 
ley Weald Brooks. Its inflorescence exserted a foot or more from the 
topmost leaf sheath was a phenomenon due no doubt to the hot summer 
sunshine combined with abundant root moisture. Mr C. E. Hubbard 
has drawn my attention to a pertinent reference (J. EcoL, 30, 232, 1942), 
where it is stated that only in very w'arm seasons are panicles properly 
exserted, and in most cases the spikelets, being already pollinated, drop 
at an early stage. The year 1859 is quoted as a good year for Leersia,. 
with hot weather in April and May. Specimens from Brockham in 
Surrey bear this out, and I remember that 1928 was a year that pro- 
duced a fine show of spikes at Amberley. However, plants observed at 
Shillinglee Park in another part of W. Sussex in Sept. 1947, varied ac- 
cording to tlie degree of wetness of the soil in which they were rooted. 
Those away fiom the water’s edge of the lake were poor and stunted 
with cleistogamous spikelets, whilst plants growing amongst Fhalaris 
and Iris, in water, had exserted panicles though not so fine as at Am- 
berley. The difference here may be due to clayey soil as against rich 
humus, etc., in the Amberley ditches. — E. C. Wallace. “In some in- 
florescences all the spikelets are cleistogamous, the relativeh* small 
anthers, about 1 mm. in length, being enclosed in the floret above the 
developing grain. In other inflorescences, some of the spikelets — usually 
very few — are definitely chasmogamous, with longer anthers (1.7-2. 2 
mm.), which, like the short stigmas, are exserted from the florets.” — 
C. E. Hubbard. “ It would seem that 1947 was an exceptionally good 
year for the flowering of this species. At Byfleet I saw even larger 
exserted panicles than the exceptionally good examples on my sheet of 
this gathering. It seems likely that this is connected with the warm 
dry summer we enjoyed and it would be useful if someone could collate 
dated herbarium material with meteorological reports over a long period 
to ascertain if the production of exserted panicles is correlated with the 
weather.” — J. E. Lousley. 
Alopecv/nis myosuroides Huds. 61, S.E. York; waste tip in field, 
roadside between Halsham and Burstwick, June 8th, 1947. — R. Lewis 
(Bef. No. 1334). “ Alopecurus myosuroides Huds.” — C. E. Hubbard. 
Calamagrostis epigeios (L.) Roth. 62, N.E. York; Pilmoor, July 
7th, 1947. Owing to the general drying out of the moor this species 
has increased considerably in the last few years and now covers quite
