gave some time to this plant. Mr. Baker points out that it is of 
importance to know the direction of the root, which in E. virgata 
is 1 simplex, descendens’ (W. & K.), whereas in E. Esula it is creep- 
ing. It is also useful to note and draw if possible the form of 
the glands of the involucre when fresh. More material, in several 
stages, would be welcomed. Will members kindly examine 
11 Euphorbia Esula L. Downs at Lewes, June 17, 1915. Coll. 
R. S. Standen” (W.E.C.R. 1915, 553) ? The glands of the invo- 
lucre have a rounded concave sinus between them, which agrees 
with Waldstein and Kitaibel’s figure of E. virgata. Sowerby’s 
figure of E. Esula shows glands with a convex projection in the 
sinus between the horns. — J.E.L. 
E. exigua L., an intermediate near var. retusa DC. About a 
quarry, Portland Isle, Dorset, Aug. 27, 1922. Seeds grey, not 
white. — H. S. Thompson. Surely much nearer type than retusa 1 
This interesting small form with imbricate leaves seems to occur 
always on purely untouched, not cultivated, ground. I cannot 
find other characters to separate it; yet it looks distinct. Mr. 
J. C. Melvill’s plant from Little Orme’s Head (B.E.C. Report, 
1901, 26) seems the same, and I have gathered it on cliffs in 
the Isle of Wight and on the west coast of Thorney, Sussex ; 
in the last station it was quite prostrate on the shore. — C.E.S. 
Urtica dioica L., var. subinermis Uechtr. Waste ground, 
Portishead, N. Somerset, v.c. 6, Aug. 3, 1922. The plant could 
be handled in comfort, as only a few stinging hairs were present. 
The leaves are rounder than usual, and it may be the var. rotun- 
data, named recently by Dr. Druce. See B E.C. Report, 1921, 
p. 307. — Ida M. Roper. I think this has too many stinging hairs 
for this variety : the branches are fairly well armed. I have not 
seen Uechtritz’s original description, but Ascherson and Graebner 
describe this variety as having no stinging hairs, or very few. —

Alnus incana DC. (1) Folly Alder Swamp, Hitchin, Herts., 
v.c. 20, July 28, 1922. For notes, see “ Journ. Bot.” May, 
1922. — J. E. Little. ( 2 ) Edge of Wood, Arnsicle, Westmoreland, 
v.c. 69a, Aug. 16, 1922. Coll. T. Cuckney. Comm. W. H. 
Pearsall. Although widely spread in Europe it has no claim to 
be considered native either in the north of England, or near 
Hitchin where Mr. Little found it recently. — A.B.J. Appears 
correct; doubtless planted. — J.F. 
Carpinus Betulus Linn. (1) [639] Denham Golf Links, Bucks., 
v.c. 24, July 1, 1922. — W. C. Barton. Near var. provincialis. —
