C. HavpENr. C. pallida, var. Haydeni, Gray, Syn. Fl. ii 
297. The characters for this, as indicated by Gray, are alto- 
gether of specific value; but to those are others to be noted, 
over and above those of the low stature, cleft foliage and 
laciniate bracts. The spike, as compared with that of C. 
pallida, is long and lax. The color of them is also not 
^ bright crimson,” but a soft rose-red, or else paler and with 
an admixture of lilac. It is a common alpine species of 
southern Colorado. 
C. coNFUSA. Perennial, the tufted stems about 11 feet 
high, green and glabrous below, more or less villous above, 
the inflorescence strongly villous with long slightly de- 
flexed somewhat viscid but not glandular hairs: lower leaves 
all lanceolate, acuminate, entire, 2 or 3 inches long; those 
under the inflorescence broader and with a pair of narrow ro 
falcately divergent lobes; bracts of the spike still shorter and — 
broader, mainly scarlet, and with two pairs of lobes: calyx | 
with four subequal lanceolate acute lobes: corolla well ex- 
serted, the galea notably villous along the back, twice the 
length of the lip, the prominent teeth of which are incurved. 
A somewhat subalpine rather large species of the more 
southerly or southwesterly Colorado Rocky Mountains, and 
those of adjacent New Mexico. It has been confused with 
C. miniata, to which it is, indeed, related; but it lacks the 
tall strict habit of that species, and its pubesceucd i of qui 
another character, that of C. miniata being sparse, short, and 
mostly gland- tipped, that of the back of the galea notably so,
