cescent + fleshy-leaved plant that we call crassifolius. Persoon’s 
original description of his variety (“Syn.” II. 354, 1807) reads: 
“ pilosus, foliol. ovatis carnosulis, caulib. foliosis prostratis, radice 
crassa fibrosa,” and we might expect from that a more hairy plant 
than Mr. Thompson’s. Rouy (“FI. Fr.”) amends and enlarges 
the description of “ var. crassifolius Ser. ap DC.” (with Persoon’s 
name as a synonym), and states that the plant may be glabrescent 
or + hairy, and mentions that the stipules are narrower (“ovales- 
lanceolees ”) than in type comiculatus. This feature I am unable 
to see in my specimens. In 1898 Mr. C. Waterfall sent in 
examples labelled var. crassifolius , from sandy ground, Spurn Head 
(see Report, 1898 — 99, p. 7), which were then referred to var. 
villosus Ser. My specimens of this gathering seem to be the 
same as Mr. Thompson’s plant. Rouy (l.c.), it will be noted, 
places L. corniculatus , var. villosus Ser. as a synonym of L. uligino- 
sus , var. villosus Lamotte. — C.E.S. 
L. tenuis Waldst. & Kit. One large prostrate plant on waste 
ground, Cranbrook Rd., Bristol, W. Glos., v.c. 34, Aug. 5, 1917. 
As Miss Roper points out, this agrees with L. peduncvlata Caven 
in its longer length, in being decumbent, and in the larger num- 
ber of flowers, but not in other respects. The peduncles averaged 
five times the length of the leaflets. — H. S. Thompson. Right. — 
E.S.M. Surely a very slender form for tenuis.— A.B. 
Vida tenuifolia Roth. Near old Park Farm, Bosham, W. 
Sussex, v.c. 13, June 24, 1917. — R. J. Burdon. Yes. — H.S.T. 
Prunus insititia L. Gt. Wymondley, Herts., v.c. 20, April 23, 
1916, July 1 and Aug. 31, 1917. A small thicket of shrubs 
about 10 feet high. Bark dark brown. Branches straight, 
somewhat spinescent. Summer shoots pubescent. Leaves : petiole 
about 15mm. pubescent; lamina somewhat obovate, obtusely 
pointed 6x4 cm., pubescent all over beneath, finely serrate. 
Peduncle (April) pubescent. Drupe (Aug. 31) egg-shaped, ave- 
raging 27 mm. x 18 mm., purple, with a bloom on the cuticle. I 
add particulars of some other gatherings of the present year, 
which has been a good one for the observation of P. insititia and 
allied forms. 
( 2 ) P. insititia L. Hoyle, nr. Heyshott, W. Sussex, v.c. 13, 
Sept. 15, 1917. Drupe globular 23 — 24 mm., yellow. Branches 
dark brown, only slightly spinescent. 
( 3 ) P. insititia L. S. of Old Park Wood, Fishbourne, W. 
Sussex, Sept. 17, 1917. Drupes 24 x 22 mm. and 22 x 20 mm.,
