R. rusticanus x ? (Ref. No. 546.) High Beech, Epping 
Forest, v.c. 18, July 13, 1921.— W. C. Barton. Yes. Epping 
Forest produces a varied and beautiful series of these hybrids. 
1 cannot put this 546 under any recognised name. — H.J.R. 
R. rhombifolius Weihe. (Ref. No. 548.) Oxshott Common, 
Surrey, v.c. 17, July 14, 1921. — W. C. Barton. I certainly think

panicles are weak, but otherwise good ; the stem leaves, however,

Barton and I were together when we gathered it, and we felt 
that much of the material we saw was abnormal, partly owing to 
the extraordinary season. — H.J.R, 
R. 1 leucanthemus P. J. M. (Ref. No. 526.) Wimbledon 
Common, Surrey, v.c. 17, July 12, 1921. — W. C. Barton. (The 1

R. echinatus Lindl. (Ref. No. 552.) Abrook Common, Surrey, 
v.c. 17, July 14, 1921. — W. C. B. Yes; but rather off type. —

P. erecta x procumbens = P. subereda Zimmeter. Garden at 
Millard’s Hill House, near Frome, Somerset, with G. B. Milne- 
Redhead, who got it wild in the district, August 10, 1921. 
Leaves mostly sessile, some stalked. — H. S. Thompson. I think 
this is correctly named, although fruit is freely produced. —
