Linn. Trans. XII. p. 198. Mr Woods on British species of Rosa

"The characters proposed by Brit. Bot to distinguish R. villosa from R. tomentosa, viz the small ovate fruit & hooked prickles do not by any means regularly go together". The size & shape of receptacle vary much in following varieties of R. tomentosa, & even on same bush of the particular variety described as the type they may be observed large & small, more or less elliptic more or less covered with setæ or quite naked.— Fourteen varieties described from different localities, of these he says some may be species, yet there are many other varieties which cannot be classed with any of the 14 & yet the distinctions are exceedingly trifling.—

p. 232. in Rosa arvensis the midrib of the leaflet is sometimes furnished with hairs, this peculiarity will occasionally occur on some branches & not?? on others on the same plant. — The varieties of many of the Roses seem endless. — in several cases differences hard to be expressed.
