76 Coville New Plant* from Southern California, 



in the throat of the corolla; anthers oblong; ovary and included 

 style sparingly short hairy ; style tips very short, divergent ; 

 capsule narrowly ovate, bluntly acute, 3 to 4 mm. long ; seeds 

 apparently very numerous, oblong, angulate by compression, 

 scrobiculate, 5 mm. long. 



The plant closely resembles a small congested specimen of 

 Perityle emoryi. The form of the leaves is very similar to that in 

 P. rotundifolia, but the plant, while belonging to the subgenus 

 Eutoca, differs from all its species in being suffrutescently peren- 

 nial. The cream-white corollas form another conspicuous char- 

 acter.

 Johnson Canon, Panamint Mountains, California, by Frederick 

 V. Coville. 



Potentilla eremica sp. nov. 



Plant of the sub-genus Ive&ia, perennial, in large tufts from a 

 branched caudex, villous-canescent throughout ; stems few, erect 

 or procumbent, 10 to 20 cm. high, sparingly short-leafed ; rad- 

 ical leaves many, the largest 13 cm. long, terete ; leaflets some- 

 times 60 pairs, entire, broadly ovate, acute or obtuse, 2 to 2.5 

 mm. wide, closely imbricated in 2 rows along the.rachis; stem 

 leaves similar, shorter, borne at intervals of about 1 to 2 cm., 

 the uppermost not exceeding 1 cm. in length ; cyme narrow, 

 about 5 cm. long; bracts simple or few-cleft, about 3 mm. long; 

 pedicels 5 to 7 mm. long, erect ; calyx 3 to 4 mm. long, lobes 

 lanceolate-acuminate; calyx bracts ovate; stamens 20; pistils 

 apparently 2 or 3 ; hairs of the receptacle dense, conspicuous, 

 1 to 1.2 mm. long. 



This plant was collected in winter, so that only the remains of 

 the inflorescence of the preceding year were found. The leaves 

 at first sight closely resemble those of P. santolinoides. The 

 plant was found in but one place, about two miles east of 

 Watkins' ranch (and about one-half mile south of the u devil's 

 hole v ), in an alkaline limestone marsh on a sloping gravelly 

 mesa, growing with Spartina gracilis, Anemopsis calif or iiica, and 

 Schcznus nigricans.
