less sprinkled with glands, tomentose within, shorter than the 
corolla, reflexed and deciduous; styles combined or collected into 
a glabrous column ; flowers rosy-white or white.—This species, 
by its habit, resembles R. sempervirens, but differs in its deciduous

guished therefrom by its straight stem, pubescent and somewhat 
glandular petioles, and deciduous leaves pale beneath.” 
Crépin regards Bastard’s species as a sempervirens X arvensis, 
and Rouy and Foucaud as a sempervirens x stylosa. Keller, how- 
ever, in Asch. & Graeb. Fl. Mitt. Kur., treats it as one of the stout, 
suberect subspecies of R. arvensis, associating it with R. cons iowa 
Bor. and &. rusticana Déségl., while R. sempervirens x arvensis 
marked examples look very different from those at the other 
extreme of R. arvensis, and I think it deserves retention at least 
as a variety. 
There are three of Bastard’s own gathering at Kew. The 
prickles are very stout-based and hooked but not large.

too young to show its shape, and the styles cannot be seen. The
