in cart-tracks and dips on the surface of the pit were much 
larger in every way than those on the more exposed level 
ground : from this' I infer that pygmaeum is in all probability 
only an ecological state. — J. E. Lousley. I do not know 
var. Pygmaeum, so I cannot offer an opinion. Plants of the 
group vary so much in size under different conditions, that 
there are likely to be dwarf forms, e.g. I found T. procumbens 
in 1926 only 2-3 in. high — but also huge plants 2 ft. elsewhere. 
-J. E. Little. I do not know var. pygmaeum Soy. -Will, nor 
have I his original description. This slender little plant may 
be var. microphyllum Ser. in D.C. Prodr. II, 206 (1825) — 
“ parvulum, foliis minutissimis, capitulis paucifloris.” It 
also agrees with var. pauciflorum Coss. and Germ. FI. 
env. Paris, 132 (1845), “ plante tres grele, a capitules 2-8 
flores.” They are probably synonymous. A few of the heads 
in Mr. Lousley’s specimens are 10-fld. and from his notes I 
gather that many intermediates occurred between the normal 
form and this slender state of exposed bare ground. — C. E. 
Salmon. 
Trifolium filiforme L. (Seeds), Old Cricket Field, Hitchin, 
Herts., July 17, 1926.— J. E. Little. Mr. Little also sent 
packets of seeds of T. diibium from Windmill Hill, Hitchin. 
Lotus corniculatus var. crassifolius Pers. [1408]. Shingle 
west of Middleton, W. Sussex, v.c. 13, August 28, 1927. 
Only, I believe, an ecological form, found inland as well as 
on the coast. — E. C. Wallace. 
Vicia tetrasperma Moench var. tenuissima Druce. Road- 
side near Leigh, Surrey, May 29, 1927. Some of the lower 
leaves approach type tetrasperma. — J. E. Lousley, Ref. 126. 
1 see nothing in these but small and rather starved specimens 
of V. tetrasperma, with rather acute but short leaflets. — H. S. 
Thompson. Since receiving the above note from Mr. 
Thompson I have carefully examined the material in the 
Herbarium of the British Museum. Fries (Novitiae Florae 
Suecicae, p. 231, 1828) gives a description — “ foliolis linear- 
lbus acutis, pedunculis unifloris.” The British Museum has 
plants collected by Dr. Druce from “ Wolvecote,” and 
" King’s Cliffe, North’ton,” which are marked as the variety, 
but I fail to see that the leaves are more linear than in im- 
plants or in the average specimens of tetrasperma. In fact 
the only striking example in the whole series is a plant from 
Herne Bay, 10/6/68 (collector not stated) which has extremely
