Flora of South Fork of Kings River. 41 



unequal-sided, suborbicular, deeply toothed, almost an inch long ; 

 upper leaves smaller and almost sessile. Inflorescence open and 

 sparingly branched ; flowers yellow, small, less than half an inch 

 across ; petals as long as the sepals, broadly ovate, obtuse ; 

 sepals ovate, with pointed tips, alternating with bractlets much 

 smaller and not half as long. Millwood, Bubbs Creek. 



Potentilla Breweri Watson. Stems several, low, from a 

 branching caudex, more or less densely clothed throughout with 

 white, silky hairs. Leaves pinnately-compound, mostly radical ; 

 those on the stem with the stipules more conspicuous than the 

 blades ; leaflets 7-13, crowded, palmately-lobed, with linear, acute 

 divisions, cuneate in general outline. Flowers about Yz in, in 

 diameter, few, in a terminal cyme ; divisions of the calyx tri- 

 angular, pointed, the alternating bractlets lanceolate and a little 

 shorter ; petals yellow, orbicular, surpassing the sepals. Bullfrog 

 Lake. 



Horkelia tridentata Torr. Stems several, from a woody root, 

 hoary with long, silky white hairs. Leaves pinnately-compound 

 with 3-9 leaflets ; those at base on long petioles ; those on stem 

 becoming smaller and almost sessile ; leaflets small, with 3 teeth 

 at apex ; stipules conspicuous. Flowers very small in crowded 

 capitate cymes, terminating the stems ; sepals triangular, pointed, 

 alternating with narrowly-linear bractlets about the same length ; 

 petals white, lanceolate, scarcely longer. This is common under 

 the pines. Collected at Millwood and Converse Basin. 



Horkelia unguiculata Rydberg. Stems many, from a woody 

 root, about a foot high, densely clothed with long, silky hairs 

 throughout. Leaves linear in outline, with numerous, crowded 

 leaflets which are divided into linear segments to the very base. 

 Flowers crowded in capitate cymes at the ends of the stems ; 

 divisions of the calyx and bractlets narrowly-triangular, long- 

 pointed, almost the same length, minutely serrulate ; petals white, 

 with broad, obovate-orbicular blade, truncate along the apex, sur- 

 passing the calyx. Millwood. 



Horkelia pygmaea Rydberg. Low, with a much branched 

 caudex, from a woody root. Leaves almost all radical, linear in 

 outline, 1-2 in. long, narrow, with the leaflets crowded, elliptical- 

 obovate, tipped with a flne bristle, glandular, very small, ib in. 

 long or less. Flowers yellow in cymes terminating the stems, a 

 little more than X in. in diameter ; sepals as long as the petals, 

 the bractlets linear, double ; petals obovate, obtuse. This is com- 

 mon near East Lake and in similar situations at the same altitude.
