Bracts whitish or yellowish; galea shorter than the corolla- 

 tube. 



Galea short and broad. C. pallescens. 



Galea slender. 



Pubescence harsh. C. lutescens. 



Pubescence soft, pilose. , C. camporum. 



Bracts scarlet or crimson, occasionally yellow; galea as long as 



or longer than the corolla-tube. 



Leaves and bracts cleft into linear lobes. C. angustifolia. 



Leaves and bracts entire. C. miniata. 



Castilleja pallescens (Gray) Greenman. Whole plant ashy puberulent; 

 stems several, erect from a woody base, 10-30 cm. high; leaves rather rigid, 

 mostly 3-5-parted with linear lobes, 2-3 cm. long; bracts similar, broader, 

 the upper with their tips whitish or yellowish; calyx deeply 2-cleft, the lobes 

 notched at the summit; corolla yellowish, the galea short and broad, the lip 

 somewhat saccate. Dry soil, especially in the sagebrush region. 



Castilleja lutescens (Greenman) Piper. Erect from a woody base, 30-50 

 cm. high, harshly short-pubescent throughout; stems simple or branched above; 

 leaves lanceolate-linear, attenuate, all but the upper entire, 3-5 cm. long; 

 upper leaves and bracts broader, 3-5-lobed, the bracts yellowish; calyx equally 

 cleft before and behind, the divisions 2-cleft; corolla yellowish, exceeding the 

 calyx; upper lip twice as long as the prominently 3-lobed lower lip. Dry 

 hillsides, common. 



Castilleja camporum (Greenman) Howell. Stems erect, 15-50 cm. high 

 with soft-pilose somewhat viscid pubescence; leaves lanceolate, a few of the 

 lower entire, the upper cleft into 3-7 narrow lobes; inflorescence pale, greenish- 

 yellow, elongated in fruit; calyx 2-2.5 cm. long, equally cleft before and behind, 

 the lateral divisions 2-lobed or rarely entire, obtuse at apex; corolla longer 

 than the calyx; upper lip nearly twice as long as the prominently 3-lobed 

 lower lip. Low meadows, rare. 



Castilleja angustifolia (Nutt.) G. Don. Stems usually clustered from a 

 woody base, erect, 20-50 cm. high, more or less pubescent throughout, some- 

 what pilose; leaves pubescent, the lower linear or linear-lanceolate, mostly 

 entire, the upper broader, cleft to about the middle into 3-5 narrow lobes; 

 inflorescence short and dense, becoming elongate in fruit; bracts like the leaves 

 but broader and more deeply cleft, pilose below, the tips scarlet, rarely yellow; 

 calyx 2-3 cm. long, with lanceolate lobes; corolla 2 cm. long, the upper lip 

 hardly as long as the tube, much longer than the short 3-lobed lower lip. 

 Thatuna Hills, Kamiack Butte and Snake River Bluffs; very variable. 



Castilleja miniata Dougl. Glabrous below the inflorescence; stems erect, 

 simple or nearly so, 30-100 cm. high; leaves lanceolate or linear-lanceolate; 

 acute or acuminate, entire, sessile, 3-5 cm. long; spikes dense, pubescent; 

 bracts broad, mostly 3-5-toothed or cleft, scarlet-tipped, shorter than the 

 flowers; calyx about equally cleft before and behind, the divisions 2-cleft; 

 corolla yellowish, 3 cm. long, the upper lip straight and slender, longer than 

 the tube; lower lip very short; pod ovoid, 10-12 mm. long, enclosed in the 

 calyx. Low ground, common. 



344. ORTHOCARPUS. 



Low annuals, very similar to Castilleja; calyx 4-cleft; corolla 

 tubular; the upper lip (galea) scarcely longer and usually much 

 narrower than the inflated 1-3-saccate lower ones; anthers un- 

 equally 2-celled, or the smaller anther-cell rarely wanting.
