Pringle labelled his specimens Potoitilla subviscosa Greene (near 

 P. VVJieeleri Wats.). I think, however, that it .should be referred to 

 P. WJieeleri rather than to P. subviscosa, as it does not have the dis- 

 sected leaves and the subunguiculate petals of P. subviscosa. 



PoTENTiLLA SUBVISCOSA Greene, Bull. Torn Bot. Club, 8 : 97. 1881. 



Differs from P. WJieeleri in the leaflets, which are deeply 

 cleft into oblong divisions, and the middle one often 3-divided to 

 near the midrib, in the petals which are more or less plainly un- 

 guiculate and about one-half longer than the sepals, in the more 

 hirsute pubescence which is intermixed with numerous glands. 

 It resembles closely the figure of P. Dombeyi in Nestler's Mono- 

 graph, but neither Nestler nor Lehmann mention anything con- 

 cerning the glands or the unguiculate petals. P. Dombeyi was de- 

 scribed from specimens from Chili, but has been reported from 

 Mexico. I have not seen any specimens and doubt its existence 

 there. P. subviscosa grows in Arizona and New Mexico. 



POTENTILLA RAMULOSA n. Sp. 



Stems several from the thick perennial root, about i dm. high, 

 scarcely exceeding the basal leaves, more or less hirsute, and 

 branched. Stipules lanceolate, the lower scarious and brown, the 

 upper herbaceous ; basal leaves on hirsute petioles 5-8 cm. long, 

 finely pubescent, in age shining ; leaflets 5-7, obovate, coarsely 

 and generally doubly toothed with somewhat divergent teeth, 

 prominently veined beneath, the larger 5-7 cm. long. Flowers 

 slender-pediceled in an open cyme ; calyx and pedicels hirsute 

 and with numerous sessile glands; bracts oblong, a little shorter 

 than the oblong-ovate sepals ; both distinctly veined, in fruit in- 

 curved and inclosing the rather few large achenes ; petals obcor- 

 date, deeply emarginate and evidently contracted in a short claw ; 

 stamens 15-20; pistils rather few; achenes striate. (Plate 276.) 



P. ranmlosa resembles P. subviscosa., but is a much larger plant. 

 The leaves, by their size, pubescence and form, remind one some- 

 what of P. Nuttallii and P. Blaskeana. The leaflets reach a length 

 of even 7 cm. The general habit, form of calyx and corolla, etc., 

 are those of P. sub^'iscosa^ but the achenes are striate. The follow 

 ing specimens have been examined :
