Rumex obiusifolius x {crispus}) '’I'hames side, between Walton and 
Weybridge, Surrey, 6th August, 1894. — W. H. Beeby. “From the 
appearance of the root leaves in early summer I formed the opinion 
that the plant would probably prove to be R. obiusifolius x Hydro- 
lopathum. Dr. Focke, however, thinks not, and that the second 
parent is probably R. crispus, but reserves a final opinion until he has 
seen fully developed root leaves. In any case, it is not, I think, one 
of our usual forms of this hybrid, and for this reason I send a few 
specimens.” — W. H. Beeby. 
Euphorbia pseudo-Cyparissias, Jord. Cote Close, Egremont, 
Cumberland, 24th May, 1895. — J. Adair. “Yes.” — H. & J. Groves. 
Mercurialis perennis. Monoecious form, Cubley, Derby, and 
Shirley, Derby, May, 1895. — W. R. Linton. See ‘Journ. fiot.,’ 
1895, p. 185. I found a good many plants of the male with a few 
female flowers ; none of the other form. — W. R. Linton. 
Salix decipie?is, Hoffm. Kinson, Dorset, 13th April, 1894, and 
24th Aug., 1895. From the same two trees from which came the 
specimens of No. 30, set of British willows (1894, &c.). I have .seen 
no other from the south of England, and as yet have met with no 
specimens of the female. I prefer to label as above, feeling sure that 
A. decipiens, Hoffm. is not a mere variety of S. fragUis ; and not being 
perfectly satisfied with the suggested solution that it is S. fragilis x 
triandra. There seems, however, no doubt that the late Dr. F. B. 
AVhite was right in identifying it with A. fragilis var. porcellanea 
Baenitz. — Edward F. Linton.* 
A phylicifolia^ Linn.; auct. Four forms are sent to illustrate this 
variable species, which have been grown in light soil at Bournemouth 
slightly improved by peat and refuse. These are No. 76 ( $ ) from 
Braemar, S. Aberdeen, a typical form, with grey pubescent capsules, 
and foliage, as usual, more glabrescent than in the wild state. No 38 
( $ ) from a rocky corrie near Clova, Forfar, has villous capsules, and 
a stigma that recalls the stigma of A Myrsinites; but it is a pure pJiy lid- 
folia form. No. 40 (°) is a neat small-leaved leiocarpa form, brought 
from the side of the White Water, Clova, Forfar. Each of these main- 
tains its distinctive features year by year. No. 16 (ty) came from 
the river side, Killin, Mid Perth, and may be considered typical as a 
lowland form of the species.— Edward Pk Linton. 
A nigricans, Sm., form or (?) hybrid. Originally from Ben Lawers, 
Mid Perth; cult. Bournemouth, No. 137, 14th May and 26th June, 
1895. Fhere is good evidence of A Arb?/scula having entered into 
this willow, remotely; note the size, texture, and raised reticulation, and 
mitigated blackening of the leaf. Some of the foliage has kept a good 
* Soon after writing the above note I discovered two low-growing trees of 
.S', decipiens, Hoffm., at Parkstone, which is therefore a .second station for Dorset, 
3 or 4 miles from the Kinson one. These are, as usual, male. — Edward F. Linton.
