Comparatively common in central California as far south as Santa Barbara. Speci-

Stems several from a perennial root, simple, 2-4 dm. high, finely pubescent, very 

 rarely a little glandular above, often reddish tinged. Stipules ovate, 5-8 mm. long, 

 often toothed. Basal leaves numerous, short-petioled ; leaflets 7-1 1 pairs, densely and 

 finely pubescent, not at all glandular, obovate-cuneate to nearly reniform, deeply cre- 

 nate-toothed at the apex, entire at the base, 5-10 mm. long. Stem leaves smaller, with 

 fewer cuneate or oblong leaflets. Cyme with rather short erect or spreading branches. 

 Hypanthium finely pubescent, rarely little if at all glandular, cupulate with the depth 

 about one-half the width ; bractlets ovate, a little shorter than the ovate-lanceolate acute 

 sepals. Petals spatulate-oblong, a little exceeding the sepals. 



It is a native of Lower California and the most southern part of California. A few 

 specimens are a little glandular on the upper part of the stem, and approach H. cuneata, 

 which the species most resembles in habit, while the pubescence is more like that of H. 

 sericea, but shorter and finer.

Stems numerous from a woody branched caudex, simple, 2-4 dm. high, grayish- 

 strigose, not at all glandular. Stipules ovate to ovate-lanceolate, acute, mostly entire. 

 Basal leaves numerous, densely appressed-silky canescent, pinnate; leaflets 6-11 pairs,
