564 RYDBERG: Rocky MOUNTAIN FLORA 
black-hairy ; teeth nearly 2 mm. long and subulate; pod fully 
2 cm. long and 3 mm. wide, sessile, linear, straight, glabrous. 
This species is nearest related to H. campestris and H. hylo- 
philus ; but differs from both in the peculiarities of the terminal 
leaflets. It has broader and less hairy leaflets than the former 
and narrower and longer than the latter. It grows on hillsides.

- Ceanothus subsericeus sp. nov. 
A small shrub, apparently not spiny ; bark of the stems gray 
or brown; of the twigs light gray and finely pubescent ; leaves 
short-petioled ; petioles 3-6 mm. long ; blades elliptic or elliptic- 
lanceolate, acute at both ends, 2-3 cm. long, more or less gland- 
ular-denticulate, 3-ribbed, sparingly strigose above, grayish-silky 
beneath ; umbels axillary and terminal ; peduncles 3-10 mm. 
long ; pedicels 5-10 mm.; calyx about 3 mm. in diameter ; sepals 
semi-orbicular ; petals white, broadly spatulate, clawed, 1-5 mm. 
long ; fruit dark brown, about 4 mm. in diameter, slightly 3-lobed 
above. 
This species is intermediate between C. ovalis pubescens and C. 
Fendleri, 1n habit it resembles most the latter, but differs in the 
denticulate leaves and in not being spiny. From the former in 
the smaller size, the silky, instead of villous, pubescence and the 
principally axillary umbels. C. sudbsericeus grows in the foothills 
at an altitude of about 1,800 m.

“ Sphaeralcea Crandallii sp. nov. 
Perennial, about 6 dm. high; stem simple, sparingly stellate ; 
petioles 3-4 dm. long; leaf-blades cordate in outline, 5-lo ed, 
about 5 cm. in diameter ; lobes lanceolate, coarsely toothed ; 1" 
florescence mostly terminal ; pedicels and calyx sparingly and 
finely stellate ; bractlets subulate, nearly equaling the Janceolate 
long-attenuate sepals ; petals white or nearly so, about 2.5 cm. 
long, cuneate and slightly emarginate ; fruit not known. 
This resembles a small S. rivudaris, but differs in the long 
bractlets and the lanceolate sepals. It grows at an altitude of 
about 2,000 m.
