that for certain plants it is impossible to choose between the two 
names.” '1 his is certainly a puzzling plant. I agree with the Rev. 
A. Ley in thinking that it cannot be referred to P. sciandica, and still 
less to P. Mougeotii , which name has, I believe, been given to it. The 
incisions between the lobes are deepest beyond the middle of the leaf, 
which is not the case in the three species already named, but I 
hesitate whether to call it P. eu-Aria or P. rupicola. The former has 
leaves quite as deeply lobed, but the number of veins, from 7 to 10 
on each side, indicates its affinity with P. rupicola , if the latter be 
considered deserving of a name. Year by year I incline more to the 
belief that P. rupicola is P. eu-Aria growing in uncongenial con- 
ditions — poor soil, exposure to- wind, or deficient heat. — J. T. Boswell. 
Pyrus communis , var. Py raster. Hatton, May, 1882. — R. L. 
Baker. Probably, but fruit is needed. — T. R. Archer Briggs. 
Epilobium montanum , L. var. Garden at Alstonfield, N. Stafford- 
shire. These seedlings closely resemble the parent plant, which 
originated in my garden — no other species being found there. After 
cultivating it Mr. H. C. Watson wrote me that, notwithstanding the 
first-sight likeness to E. lanceolatum , he could only consider it (as I 
had done) a var. of E. montanum , and that Mr. J. G. Baker con- 
curred. — W. H. Purchas.

Calliiriche vernalis. River Wye, Millersdale, Derbyshire, June,

Sedum Forsterianum , Sm., var. virescens. Occupying damp 
shady cliffs on both sides of the Rhaidr Falls bounding the counties 
Montgomery and Denbigh, 4 miles west of Llan-rhaidr, July, 1882. 
Quite green ; larger in all its parts than the glaucous form of S. 
Forsterianum. This is the same plant as I have in other years sent 
to the Club from a precisely similar situation at Water-break-its-neck, 
Radnorshire; but I am in entire doubt whether it should be referred 
to this species or to S. rupestre , Huds. It does not agree in size with 
the description of Mr. Borrer’s specimens of the var. virescens of S. 
Forsterianum in Eng. Bot. ; which are stated there to be “ more 
slender than the var. glaucescens .” — Augustin Ley. “ I think there 
are two sub-species of rupestre , viz. : — 1. S. pruinatum , Brotero = 
S. elegans , Lejeune. 2. S. Forsterianum. Sm. = A. aureum , Wirtg., 
and that this represents the latter excellently.” — J. G. Baker. “ I 
think rightly named by Mr. Ley, though more robust than the true 
Forsterianum.” — J. T. Boswell.
