silky cuneate leaflets, which are slightly crenate at the apex. P. crinita grows on the 
dry plains of Arizona, New Mexico, southern Utah and Colorado.

Caudex branched. Stems 3-4 dm. high, branched, slender but strict, more or less 
tinged with brown, slightly silky-strigose. Upper stipules ovate-lanceolate, entire, 
5-10 mm.long, the lower brown, scarious and 15 mm. long. Basal leaves several, pin- 
nate, grayish appressed-silky; leaflets 83-5 pairs, 1-2 cm. long, of rather firm texture, 
oblong, entire or 3-toothed at the apex, or with a few additional small teeth above the 
middle. Cyme branched, open, with slender pedicels. Hypanthium finely  strigose, 
cupulate, in fruit 3-4 mm. in diameter; bractlets linear, about half as long as the lanceo- 
late acuminate sepals. Petals yellow, obovate, about equalling the sepals in length. 
This species should, I think, be placed as an appendix to this group. It has no re- 
lationship to any of the Jvesias, and is a true Potentilla in every respect, except as to 
the number of pistils, which are only half a dozen or so. Its nearest relative is, without 
doubt, Potentilla crinita, from which it differs by the longer, narrower and fewer leaflets, 
the sparser pubescence, the few pistils and the longer hairs on the receptacle. 
New Mexico: Lemmon.
