64 MEMOIRS FROM THE DEPARTMENT OF BOTANY OF COLUMBIA UNIVERSITY 
Potentilla gracilis rigida Coville, Cont. U. 8. Nat. Herb. 4: 96. 1893. 
Potentilla etomentosa Rydb. Bull. Torr. Bot. Club, 24: 8. 1897. 
(?) Potentilla olopetala Lehm. Rey. Pot. 78. In part. 1856. 
Stem 4-5 dim. high, slightly hairy, erect, from a stout caudex. Stipules ovate to lanceo- 
late, entire; leaves with long petioles, digitate, of about 7 leaflets, glabrate above, slightly 
silky-strigose beneath but without any trace of tomentum ; leaflets obovate, 8-5 cm. long, 
cerenate or serrate with ovate teeth. Hypanthium hirsute ; bractlets oblong, a little shorter 
than the ovate pointed sepals. Petals obcordate, scarcely exceeding the sepals. 
This most resembles P. pulcherrima, but is perfectly without tomentum and only 
slightly hairy. It resembles P. Nutta//ii only in the lack of tomentum. It has the crenate 
obovate leaves of P. pulcherrima, and if not held distinct must be regarded as a variety 
of that species. The distribution is quite different, P. pulcherrima not having been col- 
lected in California. The following are the specimens seen : 
California: Fremont, No. 162, 1846 (type); J. S. Newberry (Williamson Expedi- 
tion); Munson & Hopkins, 1889; Coville & Funston, No. 1399, 1891; J. G. Lemmon, 
No, 84.

Intusrrations: Nestler, Monog. pl. 8. 
Stem slender, 3-4 dm. high, sparingly silky, 1-2-leaved. Basal leaves with with long slender 
petioles, digitately 5-foliolate, silky-ciliate or glabrate ; leaflets 83-5 em. long, obeordate, thin, coarsely 
serrate. Cyme narrow, almost racemose. Bractlets lanceolate, two-thirds the length of the lanceolate 
sepals. Petals yellow, obcordate, nearly twice as long as the sepals. 
The Mexican specimens seem to have a somewhat narrower cyme than the European but differ in 
no other respect, as far as I can determine. | 
Mexico, State of Coahuila: Dr. E. Palmer, No. 327, 1880.
