130 MEMOIRS FROM THE DEPARTMENT OF BOTANY OF COLUMBIA UNIVERSITY. 



cuneate, entire at the base, coarsely toothed above, 5-10 mm. long. Stem leaves smaller 

 and with narrower leaflets. Cyme rather closely flowered with short branches. Hypan- 

 thium densely appressed-hoary or strigose-canescent, cupulate, about half as deep as 

 wide ; bractlets and sepals broadly lanceolate, the former generally somewhat smaller. 

 Petals broadly spatulate, a little exceeding the sepals. 



The original specimens of this species are lower and less hairy than those of later 

 collections. These have generally been labeled H. Bolanderi, of which it is perhaps only 

 a variety, differing mainly in the appressed pubescence and the form of the hypanthium 

 and bractlets. Coville & Funston's specimens seem, however, to connect the two by the 

 more spreading pubescence. It is a native of Southern California. Specimens seen :

Caudex rather slender, much branched and somewhat tufted. Stems several, in the 

 original specimens less than 1 dm. high and nearly scapose, in later specimens 2-3 

 dm. high and more leafy, slender, finely villous. Stipules lanceolate, 5 mm. long, mostly 

 entire. Basal leaves numerous, pinnate ; leaflets 6-11 pairs, loosely and densely villous 

 or hoary-canescent, cuneate, about 5 mm. long, entire at the base, coarsely 3-5- 

 toothed at the apex. C^yme in the original specimens dense, subcapitate, in later ones 

 more open. Hypanthium densely villous or hoary, about 4 mm. in diameter in fruit 

 saucer-shaped, about a third as deep as Avide; bractlets linear-lanceolate, generally much 

 shorter than the broadly lanceolate sepals. Petals oblong-spatulate, apparently cream 

 color, about a third longer than the sepals. 



Bolander's type specimens are very low and cespitose, but those of later collec- 

 tions can not be separated from P. Bdandcrl, although the general habit is quite differ- 

 ent. The flower is identical and the pubescence of the same nature, but slightly sparser 

 It seems to be a very rare or local plant, growing in alkaline soil. Specimens seen ■
