wide range of plants he puts under it, it evidently covers more 
than Mr. Salmon’s idea of the plant, and indeed would appear 
to be the var. nanum, Milde, as are most of Newman’s plants. 
If Milde is correct, the Irish plants are var. nudum, Duby. The 
smaller and more slender forms are nanu/n, Milde, “ caulis pro- 
cumbens vel apice ascendens, tenuissimus 6 in. longus, 4-5 angulus, 
nudus.” While the very slender plant “Caulis 6-8 angulus, 2-8 in. 
altus, erectus nudus 1 . vage ramosus ” is var. tenue, Doll, ‘ Rhein 
FI.’ p. 29, 1843.— G. C. Druce. 
Equisetum palusire, L., forma lo?igiramosa, Kling. Bog, near 
Walton Junction, S. Lancs., v.-c. 59, Sept. 1907. — J. A. Wheldon. 
Equisetum limosujn, L., fluviatile, L. Magdalen Meadow, 
Oxford, June 6, 1893. — G. C. Druce. 
Equisdum hyemale, L., var. Aloorei, Newman. Sand banks, 
near Rockfield, Co. Wicklow, June, 7909. — G. C. Druce. Correct. 
The material before me is, however, rather poor. A good species 
I believe. — E. S. Marshall. 
Equisetum trachyodon, Braun. In one station in a wet hedge 
bottom, Glen Car, Co. Sligo, June, 1909. — G. C. Druce. Some- 
what stouter than my two sheets of E. trachyodon from Colin Glen, 
Belfast ; but otherwise matches them well. — E. S. Marshall. 
Lycopodium alpinum, Linn , var. S.-W. slope of Geal-Charn at 
2,700 ft., Glen Feshie, E. Inverness, v.-c. 96, July, 1909. — Albert 
Wilson and J. A. Wheldon. This plant when growing looks very 
distinct from ordinary Z. alpinuni, which occurs more sparingly on 
the same hill. The flabellate branches have (taken with the leaves) 
a very compressed selaginella-like appearance, and are as robust as 
those of Z. annotinum, which also grows in the vicinity. When 
fresh the main stems of the variety are very distinctly angular, 
whereas those of Z. alpinum are only feebly so, in fact practically 
terete. This difference is less apparent in the dried plant, but a 
distinctly raised decurrent line may still be traced below the junction 
of most of the branches with the main stem. — A. Wilson and J. A. 
Wheldon. This is the Z. alpinum, var dccipicns, of my ‘ List,’ and 
what at one time was thought by Mr. J. G. Baker, Sir Jose|ih 
Hooker, Dr. Carruthers, &c., to be Z. complanatum, J,. (see ‘ Ann. 
Scot. Nat. Hist.’ p. 182, 1892). Curiously enough Dr. Syme, who 
was the first to doubt the identity of Mr. Baker’s complanatum with 
the Linnean type, omitted to describe it wlien treating of Z. alpinum 
in the third edition of ‘ English Botany,’ but there is a i)late (1834) 
drawn from my Gloucestershire specimen which is lettered Z. 
alpinum, var. dccipicns, strictly therefore a nomen solum, but I have 
a letter from Dr. Syme in which he says of my Gloucester specimen,
