every case added, “ if the corolla is white .” The fact is I have never 
thought of naming any rose leucochroa that had not white petals ; but, 
I must add, that is far from being the only character on which I rely 
in distinguishing this rose from other kindred stylosa and canina 
forms. Fully to justify the application of the name leucochroa to any 
bush, it should have, I think, in combination with a white corolla, a 
markedly stiff and erect habit, peduncles of moderate length, well 
clothed with setae, styles nearly or quite glabrous, leaflets just inter- 
mediate in size and outline between systyla and obtusifolia , glabrous 
above, hairy on the veins beneath, and ciliate, and prickles remarkably 
hooked (especially on the flowering shoots) also just intermediate 
between those of systyla and obtusifolia. These prickles (usually red) 
have much longer points than those of systyla and stylosa , and, 
in conjunction with the stiff habit and rather small obovate leaflets 
(sharply simply toothed, and usually dark green), make the bush 
easily recognisable. The fruit is nearly oval with disk as prominent 
as in other stylosa forms, and bearing a short style-column after 
the petals fall. In flower the styles are usually free, and variable in 
the degree to which they protrude. R. leucochroa is one of the 
commonest roses throughout Devon and (apparently) Cornwall, 
but seems rare in other parts of England. Plants from the neighbour- 
hood of Plymouth were thus named by Mr. Dese'glise for Mr. Briggs 
many year^ ago. It is well described in Boreau’s “Flore du centre 
de la France.” — W. Moyle Rogers. 
Rosa arvensis, Huds., var. gallicoides , Desegl. Stydd, S. Derby, 3rd 
October, 1888. — W. R. Linton. “ Bien nomme.” — F. Crepin. 
Pyrus torminalis , Ehrh., var. Rocks, Aberedw, Radnorshire, 
17th July, 1888. This is a deeply-cut variety, which may, perhaps, 
be worth sending. I only found a small tree or bush growing among 
abundance of P. rupicola , Syme. I believe P. torminalis , Ehrh., to 
be a new County record for Radnor. — Augustin Ley. “Scarcely 
a variety.” — Ed. “ Do.” — J. G. Baker. “ I should be content to 
name without adding ‘ var.,’ for the deep cutting of the leaves is 
hardly, I think, a sufficiently marked feature to permit us to designate 
this plant a variety.” — T. R. Archer Briggs. One of the trees in Wych- 
wood has leaves nearly as deeply incised. — Ed. 
P. scandica , Syme? Craig Breidden, Montgomeryshire, June, 
1888. I send this as not representing typical scandica , but as one of 
the intermediates between this and P. Aria , Sm., which I do not know 
which species to place to. A form very similar to this, from the 
Dowards, Herefordshire, but a step nearer to P. Aria , was named for 
me P. Aria , a few years ago, by Dr. Boswell, with the remark that he 
had never seen the leaves of the side-shoots in Aria so deeply lobed. 
I found but one shrub of this variety on Craig Breidden. — A ugustin 
Ley. “Is not this Aria l ” — J. G. Baker “This has some of the 
characters of scandica , and seems to me Aria towards scandica , i.e., 
an intermediate form.” — Arthur Bennett. “ P. latifolia, Syme.” — C. 
C. Babington. “Certainly is not P. scandica ; it is much nearer P. 
latifolia , Syme, which latter he at one time thought to be the scandica 
of continental botanists. Vide ‘Rep. B. E. Club,’ 1872-1874, pp.
