9 mm. x 10 mm. and 21 mm. x 13 mm. respectively. The largest 
leaf on the first-named is 10 cm. x 9 cm. The margin of the 
lamina is crenate, with slight irregular dentations. In the second 
the margin is more decidedly dentate, and the laminae are smaller. 
On a sheet gathered by the Medway, near Tonbridge, Kent, in 
Feb. 1879, the old catkins are very small (13 mm. x 8 mm. only). 
The “B.E.C. Report,” 1912, p. 179, has: “ Alnus glutinosa 
Gaertn., var. macrocat-pa Requien, ‘Ann. Sc. Nat.’, 1825, p. 381. 
Asch. & Graebn. ‘Syn.’ 1911, p. 419. ? catkins 3 cm. long, 
Berks. ; var. microcarpa Uechtr., A. & G. l.c. 1911, p. 419. Female 
catkins 1 — l'5cm. long and 0'5cm. broad, Northants., Oxford, 
Berks., Hants., G. C. Druce.” — J. E. Little. Yes. I have not 
come across this very large-fruited variety, which seems to be 
scarce in Britain. — E.S.M. Loudon (“ Arb. et Frut. Brit.”) says 
that this has the leaves and fruit rather larger than those of the 
species, and is also of more vigorous growth, but he gives no 
measurements, so it is not possible to say exactly what he meant 
by his var. macrocarpa. Moss (“Camb. Brit. FI.” II. 87) describes 
the fruit of var. macrocarpa as 3 centimetres long, evidently an 
extreme measurement, and probably referring only to a single 
tree. Anyone who will take the trouble to examine a sufficient 
number of Alder trees will find a great variation in the size of 
the fruits. The description of A. glutinosa , forma macrocarpa 
Callier, Fedde “Repert. nov. sp.” X. 230 (1912), is “Inflorescentiae 
fructiferae majores quam in forma typica, 20 — 25 mm. longae, 
7 — 15 mm. diametientes,” and fits Mr. Little’s specimens very 
well, and I would prefer to leave them under that. — A.B.J. 
Salix triandra L. Swamp, by G.W.R , Keynsham, N. Somer- 
set, v.c. 6, May 11 and June 21, 1917. — Ida M. Roper. Coarsely 
and bluntly toothed foliage ; under the type, I fancy. — E.S.M. 
Right.— E.F.L. 
S. alba L., var. ccerulea (Sm.) ? Copse between Gt. Wymond- 
ley and Willian, Herts., v.c. 20, July 1, 1917. Twigs olive, not 
easily detached ; catkins stalked ; capsule shortly stalked. — J. E. 
Little. Right. — E.F.L. 
S. lapponum x repens , male. (Ref. No. 2963 b). Origin : 
Lochy Burn, Glen Shee, v.c. 89, E. Perthsh , 1906. Cult^West 
Monkton, 1917; flowers, April 26; leaves, July 9. The hybrid 
— in two or three forms— has only, I think, been found on the 
banks of this stream, between 1200 and 1400 feet. — Edward S. 
Marshall.
