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 :

ILLUSTRATIONS: PLATE 63, typical form, f. 1; dissection of flower, f. 2; pistil, f. 3; 
stamen, f. 4; fruiting hypanthium and calyx, f 5; tall form, f. 6 and 7. 
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. Cyme 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 wide; 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 collee- 
tions can not be separated from P. Bolanderi, 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 :
