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. piilcJiella 

 grows on high mou;itains 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 3'ellowish 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. 

 desertornm 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. fasciadata, 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—Z, narrowly oblanceolate, 3—7 cm. long, acute, glabrous above, 

 appressed, short-hairy beneath ; inflorescence lax, i— 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; vvangs light-blue or white, 10-12 mm. long ; legume 

 3—4 cm. long, 8-9 mm. wide, densely pubescent. 



In habit resembling L. pseiidoparvifloriis and L. laxiflorus, but 

 differing in the spreading pubescence of the stem. This char- 

 acter would associate it with L. aviplns and L. ornatus glabratns S. 

 Wats. From the former it differs in the lax spike, slender stem.
