Caltha palustris L. var. Guerangerii (Bor.). Holmsley Bog, 
Beaulieu, S. Hants, v.c. 11, May 29, 1933. — I. M. Roper. 
Flowers smaller than the type ; sepals not overlapping. I 
agree. — J. Fraser. These seem to be well-marked specimens 
of the variety, showing the distinctive foliage, petals and 
carpels. — H. W. Pugsley. The follicles on the specimens 
received are far from ripe, but they appear to taper into the 
beak rather more gradually than in the usual British 
C. palustris. The crenation of the upper leaves, and arrange- 
ment of the sepals might justify the inclusion of these 
specimens under C. Guerangerii as defined by Boreau {Bill. 
Annot. 1856, p. 11), but as pointed out by Dr. Huth in his 
Iconographie der Gattung Caltha this can only be retained as 
a form. Huth states that after examining hundreds of 
specimens he found no constancy in the characters of the 
flowers, leaves, and fruits. See also Purchas & Ley, FI. 
Hereford, p. 9 (1889) ; and notes in Rep. B.E.C. 1871, p. 9 ; 
1889, p. 244 ; 1893, p. 399 ; 1895, p. 466 ; and 1904, p. 9. 
Even Boreau remarks on the fact that his plant sometimes 
occurs with the type {FI. du Centre. II, p. 21 (1857)). — J. E. 
Lousley. 
Nasturtium sylvestre R. Br. and N. palustre DC. with 
rosettes of root-leaves for comparison. Blagdon Reservoir 
and Chew Magna Reservoir, N. Somerset, Sept, and Oct., 
1933.- — H. S. Thompson. This ( sylvestre ) has the lobes of the 
leaves more deeply cut on the posterior side than N. palustre. ■ 
The pods or silicules are very distinctive between the two. — 
J. Fraser. 
Barbarea vulgaris R. Br. Autumnal root-leaves, to show 
variation. Side of stream, Bishopsworth, N. Somerset, Nov. 
7, 1933. — H. S. Thompson. 
Sisymbrium officinale Scop. Fine autumnal root-leaves, 
which often die down before summer. Corner of arable 
field, near Pensford, N. Somerset, Sept. 29, 1933. — H. S. 
Thompson. 
Brassica nigra Koch. Near Hereford, July 5, 1933. — 
R. J. Burdon. I agree. — J. Fraser. 
Capsella Bursa- pastoris Medik. [var. grossa E. At.]. Waste 
ground, Cardiff, Glam., v.c. 41, June 9, 1933. — A. E. Wade.
