R. caesius x rusticanus. Hedgerow, Tockington, W. Gloster, 
v.c. 34, Aug. 14, 1924. — Ida M. Roper. There is nothing against 
this hybrid detn. that I can see; but as Miss Roper knows what 
species accompanied the bush from which she gathered she can 
speak with more certainty. — H.J.R. Certainly a hybrid, and 
quite probably as named ; but a note of the species in the imme- 
diate neighbourhood should be sent, as it is usuall}' impossible to 
be sure of a cross from dried material alone. — W.C.B. 
Rosa 1 x Shoolbredi Wolley-Dod. Waste ground by 
Calder Burn, Newtown Moor, W. Inverness, v.c. 96, July 21, 
1911. — W. A. Shoolbred. This is R. omissa Desegl, var. typica 
R. Kell., a fairly typical form, on which no special remarks are 
called for.— A.H.W-D. 
Saxifraga umbrosa L., var. genuina Syme. Cult, at Wimbledon 
(June 15, 1924). Origin, Heseldon Glen, Yorks., 1919. — H.W.P. 
This is the variety genuina Syme, E. B., ed. iii, IV, p. 70, col- 
lected in the glen where it was originally discovered in 1792. It 
is distinguished by Syme as having “leaves spreading, in com- 
pact rosettes; lamina oblong-obovate, crenate ; petioles short,” 
while the usual Irish form, var. punctata Haworth, is diagnosed 
“leaves ascending, in rather lax rosettes; lamina obovate-round- 
ish, crenate-serrate ; petioles longer than in genuina.” The leaves 
of var. genuina are also notable for their very dark colour and 
marked cartilaginous margins, and for the remarkably broad, 
truncate apical tooth. Both of these varieties differ from the 
“ London Pride ” of British gardens, which has leaves of some- 
what intermediate form, long-petioled and ascending as in var. 
punctata , with crenate margins, but not apically truncate. Its 
flowers are larger than those of var. genuina , with broader, more 
finely-speckled petals. ThisjHorm is represented in Herb. Mus. 
Brit, by specimens from the Chelsea Garden, and by material 
from Culborne, Somerset; Thorp Arch, Yorks.; Aslnvood Dale, 
Derby ; and Dingle, Kerry, In these places it has been intro- 
duced, unless possibly wild at Dingle. 1 have seen no certainly 
wild examples that match this form, which Marshall and other 
authors do not seem to have distinguished from var. genuina. 
The variety genuina occurs in Britain only in a few Yorkshire 
glens, where it has been considered a native by Babington and 
other good botanists who have seen it in situ. It appears to be 
identical with the Pyrenean form of the species, while the Irish 
variety punctata coincides with the plant growing in the moun- 
tains of Asturias and Portugal. This interesting fact is readily 
seen on going through the material in Herb. Mus. Brit, and the
