was known prior to 1855, and placed under S. repens L. forma 
incubacea with very silky leaves. It would be highly .desirable 
that H. S. Thompson should collect the catkins of this in 
May. — J. Fraser. 
Populus candicans Ait. $. [738]. Planted, Radwell Mill, 
Herts. FIs. Mar. 13, 1928. Leg. R. Morse. Lvs. Ap. 13, 
1928, Leg. J. E. Little. Correctly named. The viscid leaves 
are very fragrant till fully developed. Only the $ tree is 
known in Britain. — J. Fraser. 
Allium triquetrum L. Hedgebanks in open country, Penally, 
near Tenby, Pembrokeshire, May 16, 1932. Looks far more 
‘ wild ’ here than in the Cornish localities where I have seen 
it. — J. W. Carr. 
Scilla autumnalis L. Cliff near Tintagel, N. Cornwall, 
Sept. 16, 1932. — H. W. Pugsley. 
Juncus compressus X Gerardi ? [2670]. Waste alluvial 
ground bv Clifton Bridge Station, N. Somerset, Aug. 17, 1932. 
By the aid of a trowel these plants were seen to have the far 
creeping rhizome of Gerardi putting up stems at intervals. 
The capsule is subglobular, obtuse and mucronate as in 
compressus ; and the perianth-segments seem usually to be 
intermediate in length. The plants however varied consider- 
ably, both in height and otherwise. — H. S. Thompson. 
J . compressus with rhizome, which appears to be quite usual 
in this species and is present in many of the specimens in 
Herb. Mus. Brit. — A. J. Wilmott and E. Drabble. This 
seems to be rather an abnormal form of J. compressus than a 
hybrid. I think that very moist soil might account for the 
creeping rootstock. Is J . Gerardi known so far up the river 
as Clifton Bridge Station \ — H. W. Pugsley. Yes, and I 
have good, tall specimens of Gerardi from close to the 
compressus colony, which latter species does not appear to 
have been seen there until recently. — H. S. T. 
Juncus maritimus Lam. Holme-next-the-Sea, near Hun- 
stanton, Norfolk, Aug. 21, 1932. — J. W. Carr. 
Juncus subnodulosus Schrank. Banks of a rhine, Walton- 
in-Gordano, N. Somerset, Sept. 4, 1932. — E. C. Wallace. 
Potamogeton pusillus L. [Ref. D 31]. Loch Clunie, East 
Perth, Aug. 11, 1932. — J. E. Lousley. A characteristic 
lacustrine form of pusillus with short leaves having a slightly 
tapering + obtuse apex with a small mucro. The lacunae on 
either side the midrib are well developed. — W. H. Pearsall.
