This variety agrees well with typical R. Mairei Lév. except that the leaves 
have 5-6 pairs of leaflets instead of only 2-4 pairs. Unfortunately the fruits 
of the type are still unknown. ReEHDER.and Witson in Sargent, Pl. Wils. 
2: 344. 1915, say that R. Mairei “is probably nothing more than a very 
hairy and small-leaved variety of R.. omeiensis Rolfe.” In my opinion, it 
seems much more closely related to R. sericea Ldl. which, however, comes very 
near R. omeiensis. The new variety may be identical with the true R. sericea,

he typical R. omeiensis Rolfe is well characterized by its OP ee eaten

beneath, and by the distinctly thickened and colored (yellow or red) footstalks 
of the ripe fruits (see Bot. Mag. 138: pl. 8471. 1912) ; but there are certain — 
hairy forms with almost subsessile fruits and f ewer leaflets which come very 
near to R. Mairei as well as to R. sericea. The type of R. sericea as represented 
by Liypiey in his Rosac. Monogr. 195. pl. 12. a has 7-1r leaflets which
