6(5). Plants 1-2 dm. tall, unbranched, strongly viscid-villous (at least in the 

 inflorescence); bracts sometimes streaked or tinged with red or 

 purple; typically in alpine situations 5. C. occidentalis. 



6. Plants mostly 2-5 dm. tall, often branched, glabrous to slightly viscid-villous; 

 bracts pale-yellow; mostly below alpine zones 6. C. sulphurea. 



7(4). Inflorescence commonly branched; primary lobes of calyx each with 2 

 linear-attenuate sharp segments 7. C. miniata. 



1. Inflorescence simple; primary lobes of calyx each with 2 short blunt segments 

 8. C rhexi folia. 



1. Castilleja coccinea (L.) Spreng. Painted cup, Indian paint-brush. 

 Annual, more or less pubescent; stem usually simple, 2-6 dm. tall; principal 



cauline leaves very diverse, varying from rarely entire to commonly 3- or 5-cleft, 

 the segments linear to narrowly oblong, the lateral ones almost always shorter or 

 narrower than the terminal one; spike at first dense and 4-6 cm. long, elongating 

 to as much as 2 dm. in fruit; bracteal leaves wholly or mostly scarlet, rarely 

 pale, commonly 3-lobed or occasionally 5-lobed; calyx 2-3 cm. long, thin and 

 membranous, often more or less scarlet, deeply divided into 2 lateral halves; 

 each calyx half gradually widened distally and at the summit broadly rounded to 

 truncate or barely emarginate; corolla greenish-yellow, little surpassing the calyx, 

 the minute lip less than a third as long as the galea. 



In wet meadows, bogs, moist prairies and wet sandy soils in Okla. (Delaware, 

 Haskell, Mayes and Muskogee cos.), May-Aug.; Mass. to Ont. and Man., s. to 

 S.C., Miss., La. and Okla. 



2. Castilleja minor Gray. Fig. 706. 



Slender annual; stems erect, simple or branched from near base, 2-10 dm. 

 tall; herbage variously pubescent but with some gland-tipped hairs, occasionally 

 glabrate below, usually somewhat viscid or "clammy"; leaves linear to lanceolate- 

 attenuate, entire, 4-10 cm. long, minutely but densely pilose, interspersed with 

 gland-tipped hairs; bracts entire, linear to lanceolate-attenuate, the lower bracts 

 green, the upper ones red-tipped; flowers in spikelike raceme, pediceled, the lower 

 flowers remote; calyx cleft medianly into 2 ovate-attenuate lobes, these cleft or 

 notched at apex; corolla short, but the galea well-exserted, the reddish lower lip 

 included in calyx or barely exserted, the galea about Vi to nearly as long as 

 corolla tube; capsule included in growing calyx, 10-12 mm. long. 



Subsaline to alkaline marshes and bogs, around springs and along streams, in 

 N. M. (Grant, Sierra and San Juan cos.) and Ariz. (Navajo, Coconino and 

 Mohave, s. to Greenlee, Cochise, Santa Cruz and Pima cos.), Apr.-Aug.; also n. 

 Mex. 



3. Castilleja exilis A. Nels. Fig. 706. 



Slender to coarse annual; stems simple or with few branches from base, 3-10 

 dm. tall; pubescence various, often of coarsely hispid-pilose hairs intermixed with 

 fine hairs or sometimes with gland-tipped hairs; leaves lanceolate-attenuate to 

 linear, entire; bracts foliaceous, lanceolate, entire, erect and scarlet-tipped when 

 young, soon becoming green, entire; flowers in a stout spikelike raceme, the 

 flowers becoming more remote after anthesis: calyx green. 15-18 mm. long, cleft 

 medianly for about two thirds of its length into ovate-attenuate lobes, these 

 entire, toothed or emarginate at apex, rarely cleft; corolla 14-20 mm. long, in- 

 cluded within or barely exserted from the calyx, the galea about one half as long 

 as tube; capsule 8-12 mm. long. 



Saline or alkaline bogs or marshes, cat-tail swamps, wet meadows and wet soil 

 near springs, in N. M. (San Juan Co.) and Ariz. (Coconino Co.), Apr.-Sept.; 

 Mont, to Wash., s. to N.M., Ariz, and Nev.
