 and entire : bracts 3-parted ; the divisions more or less spatulate-dilated and petaloid : calyx- 

 lobes broad and with rounded entire or slightly 2-lobed summit : corolla almost included, 7 to 9 

 lines long, slender ; the narrow galea little shorter than the tube ; lip very short.

 base: woolly hairs intricately branched: leaves narrowly linear (inch or less long), 

 crowded below and fascicled in lower axils : spike close : galea shorter than the tube of 

 the corolla. — Bot. Beech. 154; Benth. 1. c. ; Gray in Am. Jour. Sci. 1. c. & Bot. Calif, i.

 C. lanata, Gray. Apparently herbaceous to base, branching, white with appressed 

 arachnoid wool: leaves larger (inch or two long) ; the galea longer than the tube: flowers 

 larger, more scattered in the spike : corolla rather more exserted. — Bot. Mex. Bound. 118. 



— S. W. Texas to Arizona. (Adjacent Mex.) 



■H- -w* -H- Tomentulose or cinereous-puberulent, or the stem only lanate-tomentose : bracts, &c., 

 conspicuously petaloid : primary calyx-segments 2-cleft or 2-parted into narrow usually acute 

 lobes : corolla more exserted, inch long or over; galea shorter than the tube; 



= Lip very short; its lobes not longer than the more or less callous saccate portion. 



-C. Integra, Gray. A span to a foot high: stem rather stout, tomentose : leaves cine- 



reous-tomentulose, linear (1-J- to 3 inches long, 1 to 3 lines wide), entire: bracts of the 



short spike linear- or obovate-oblong, red or rose-color, entire or sometimes incised : corolla 



inch and a quarter long ; galea rather broad ; lip strongly tri-callous, its lobes very short.

 W. Texas to Colorado and Arizona. 



C. Lindhelmeri. A span or two high, branched or many-stemnied from the base, cine- 

 reous-puberulent or the stem tomentulose : leaves narrowly linear, entire or sparingly 

 laciniate, or the upper 3-5-cleft, as are the bracts of the dense spike ; these mostly peta- 

 loid and dilated, from brick-red to rose-color or sulphur-yellow : calyx equally colored : 

 corolla (inch or so in length) rather slender ; the lobes of the lip ovate, not longer than the 

 callous saccate portion — C. purpurea, Gray in Am. Jour. Sci. 1. i;. 338, not Don & Benth. 



— Stony or fertile mountain prairies, on the Pierdenales and Guadalupe, W. Texas, Lind- 

 heimer, &c. Much more showy than the next, and with different corolla. 



= = Lip of corolla with longer and narrow lobes, and base less saccate. 

 C. purpurea, Don. A foot or less high, minutely cinereous-pubescent and the stem 

 appressed-tomentose : leaves narrowly linear and entire, or mostly once or twice 3-cleft or 

 laciniate, with divisions and lobes all narrowly linear: bracts similar or with cuneate- 

 dilated base ; the broader lobes of tlie upper and the calyx magenta-color or purple : 

 corolla (over an inch long) narrow ; galea very much shorter than the tube, only twice the 

 length of the lip : lobes of the latter elongated-oblong, plane and petaloid, ver'y much 

 longer than the obscurely saccate and not callous basal portion. — Syst. iv. 615 ; Benth.

 •)— -I— -•— Calyx deeper cleft before than behind : corolla either slender or small, with galea much 

 shorter than its tube and lip comparatively long : bracts and calyx if colored at all vellowish : 

 leaves or their divisions narrowly linear, rather "rigid : stems numerous from the root. 



++ Lip of corolla half the length of the short galea, more or less trisacculate and little if at all 

 callous below the narrow lobes : flowers yellowish or greenish white ; clefts of the calyx moder- 

 ately unequal. 



= Cinereous-pubescent: leaves mostly 3-B-cleft and the slender divisions sometimes again 2-3- 

 cleft: bracts similar or with more dilated base, not even their tips colored. 



C. sessiliflora, Pursh. A span or two high, very leafy, cinereous-pubescent : leaves 

 2 inches or more long, with slender lobes, rarely entire : lobes of the tubular calyx slender : 

 corolla exserted, about 2 inches long: lip with linear-lanceolate lobes very much longer, 

 than the obscurely saccate base. — Fl. ii. 738; Benth. I. c. ; Gray, 1. c. C. grandifora,
