 about 4-angled, simple or mostly paniculate-branched above; radical leaves (rarely seen) 

 small and oval or oblong, thickish, hispidulous, half inch or less long ; cauline reduced to 

 appressed subulate and mostly scattered minute scales : pedicels short, rather crowded in

30. CASTILLEIA, Mutis. Painted-Cup. (Z>. Castillejo, a botanist of 

 Cadiz.) — Herbs (American, mostly N. American, and two in N. Asia) ; with 

 alternate entire or laciniate leaves, passing above into usually more incised and 

 mostly colored conspicuous bracts of a terminal spike ; the flowers solitary in 

 their axils and ebracteolate, red, purple, yellowish, or whitish ; but the corolla 

 almost always duller-colored than the calyx or bracts, mostly of yellow or greenish 

 tinge. Fl. in summer. (Primary divisions generally received are not distinct 

 enough for subgenera, except JEpickroma of Mexico, with a fannelform calyx. 

 Ours accordingly may all be embraced in § Euchroma, Euchroma, Nutt. Gen. 

 ii. 55.) — Gray in Am. Jour. Sci. ser. 2, xxxiii. 335, & Bot. Calif, i. 573. 



# Annuals or some biennials with fibrous root: at least the upper part of the bracts and sometimes 

 of the calyx petaloid (bright red or scarlet, occasionally varying to yellowish) : pubescence vil- 

 lous or soft-hirsute. 



-i— Atlantic species, flowering in spring or earl}- summer, a span to a foot high : floral leaves or 

 bracts' dilated : calyx equally cleft before and behind into 2 broad or upwardly dilated entire or 

 retuse lobes: galea' (upper lip) shorter than the tube of the corolla, little surpassing the calyx, 

 much exceeding the short lower lip. 



C. COCCinea, Spreng. (Painted-Cup.) Biennial, at least northward: rosulate radi- 

 cal leaves mostly entire, obovate or oblong; cauline and bracts laciniate or 3-5-cleft; the 

 middle lobe of latter dilated : calyx-lobes quadrate-oblong. — Syst. ii. 775 ; Benth. in DC. 

 Prodr. x. 259. Bartsia coccinea, L. Spec. ii. 602. (Pluk. Aim. t. 102, fig. 5.) Euchroma coc- 

 cinea, Nutt. 1. c. — Low sandy ground, Canada and Saskatchewan to Texas. 



C. indivisa, Engelm. Leaves lanceolate-linear and entire, or sometimes with 2 or 3 

 slender lateral lobes : bracts and calyx-lobes obovate-dilated, bright red. — PI. Lindh. i. 47 ; 

 Benth. in DC. 1. c. — Texas, Berlandier, Drummond, Lindheimer, &c. Winter-annual, flower- 

 ing in spring, no tuft of radical leaves surviving. 



-i— -)— Ultramontane and Pacific annuals, with virgate stems, mostly tall and slender: leaves 'and 



bracts all linear-lanceolate and entire ; the latter or at least the upper with petaloid (red) linear 



tips : flowers all pedicellate, the lower rather remote in the leafy spike : calyx gibbous and broadest 



at base, ovoid or oblong in fruit, wholly green, about equally cleft before and behind to near the 



middle ; the segments lanceolate and acute or acutely 2-cleft at apex : galea of the narrow and 



straight corolla very much longer than the small not callous lip : capsule oblong. 



C. minor, Gray. A foot or two high : corolla half to three-fourths inch long, yellow : 



the oblong galea much shorter than the tube. — Bot. Calif, i. 573. C. affinis, var. minor, 



Gray, Bot. Mex. Bound. 119, & Am. Jour. Sci. 1. c. — Wet ground, New Mexico and 



Nebraska to W. Nevada. 



C. stenantha. Taller, 1 to 5 feet high : corolla linear, double the length of that of the 



preceding species ; the slightly falcate and commonly reddish galea one-half longer than 



the tube.— C. affinis, Benth. PI. Hartw. 329, in part (no. 1897); Gray, 1. c. in part.—
