30. CASTILLfilA, Mutis. Painted-Cup. (-D. 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 Epichroma of Mexico, with a funnelform 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. 



H— Atlantic species, flowering in spring or early 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. (Paixted-Cup.) Biennial, at least northward: rosulate radi- 

 cal leaves mostly entire, obovate or oblong ; cauline and bracts laciniate or .3-5-clef t ; 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-Unear 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— H— 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 iipper 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. ajfinis, 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-lialf longer than 

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