RyDBERG: Rocky MouNTAIN FLORA 
Pachylophus hirsutus sp. nov. 
Cespitose, almost acaulescent perennial ; leaves oblanceolate 
in outline, 1-2 dm, long, more or less petioled, runcinate-pinnately 
lobed or divided, hirsute-villous, especially on the margins and the 
veins ; teeth or lobes acute; hypanthium 8-12 cm. long, slender, 
widening upward, conspicuously hirsute, at the throat 1-1.5 cm. 
wide; sepals lanceolate, 3—4 cm. long, soon reflexed ; petals ob- 
cordate, 3~4 cm. long; pod 4~—5 cm. long, lance-ovoid, about I 
cm.in diameter, sessile ; ridges low and rounded, slightly if at all 
tubercled. 
In general habit, this species resembles most P. macroglottis 
and P. marginatus. From the former it differs in the hairy hy- 
panthium and calyx, the more hairy leaves and the longer and less 
tubercled fruit. From the latter it is distinguished by the sessile 
pod and always subacaulescent habit. /. Airsutus grows at an 
altitude of 2,200~—3,000 m.
