RyDBERG: Rocky MouNTAIN FLORA 41 
It has the habit, pubescence and coloration of the latter but the 
leaves, bracts and calyx-lobes of the former; the form of the 
corolla is intermediate between those of the two. C. pulchella 
grows on high mountains at an altitude of 2500-3300 m.

Castilleja Pecten 
Perennial ; stem stout, 4-5 dm. high, puberulent throughout ; 
lower leaves linear, entire, 5-6 cm. long, puberulent; the upper 
3-5-cleft with linear divisions ; bracts rhombic-obovate or broadly 
cuneate in outline, almost pectinately cleft into -linear divisions, 
puberulent, upper portion yellowish .or the tips brownish ; calyx 
about 2 cm. long, puberulent, equally cleft above and below; 
lobes lanceolate, about 3 mm. long; corolla a little over 2 cm. 
long ; galea 8-9 mm. long ; lip about 4 mm. long, its lobes oblong. 
In general habit and coloration it resembles somewhat C. 
desertorum and C. lutescens, but the lower lip is nearly half as 
long as the galea and of different shape, and the bracts are pecu- 
liar. The structure of the corolla places this species nearest to 
C. fasciculata, but it is a much larger plant.

Lupinus marianus 
_Stem 5-10 dm. high, striate, hirsute-villous with rather short 
hairs, slender, leafy ; stipules setaceous ; petioles 4-8 cm. long, or 
those of the basal leaves even 2 dm. long, hirsute-villous ; leaflets 
6-8, Narrowly oblanceolate, 3-7 cm. long, acute, glabrous above, 
“pressed, short-hairy beneath ; inflorescence lax, 1-1.5 dm. long ; 
Pedicels 4-5 mm. long ; calyx villous, gibbous but not spurred at 
the base on the upper side ; lips lanceolate, the upper 7 mm., the 
lower 8 mm. long ; bracts linear-subulate, longer than the calyx, 
deciduous ; banner 8-10 mm. long, light-blue or white with a 
darker Spot; wings light-blue or white, 1o-12 mm. long ; legume 
3-4 cm. long, 8—g mm. wide, densely pubescent. 
In habit resembling L. pseudoparviflorus and L. laxiflorus, Laas 
differing in the spreading pubescence of the stem. This char- 
_ acter would associate it with ZL. amplus and L, ornatus glabratus S. 
_ Nats. From the former it differs in the lax spike, slender stem,
