NEW SPECIES OF CERASTIUM. 299 
bristly hairs on the midvein beneath and on the margin; 
leaves of the long and well developed sterile shoots linear, 
hirsute-ciliate at the base, otherwise glabrous, nearly ? inch 
long, longer than the internodes and spreading; all the 
stems and branches more or less hirsutulous below the nodes, 
often hirtellous nearly throughout, only the peduncles and 
pedicels glandular-hirtellous: calyx 21 lines long, almost 
glabrous, showing only a few scattered and very short 
gland-tipped hairs: corolla large, of more than twice the 
length of the calyx: capsule very short, not even the 
relatively very long teeth exserted from the mature calyx. 
Rocky Mountains of Colorado, southward chiefly, and at 
considerable elevations only; well represented in Baker, 
Earle and Tracy’s nn. 497, 664 and 892, all from subalpine 
stations in the La Plata Mts.; the species perhaps also 
embracing Mr. Wooton’s n. 639 from the White Mountains, 
southern New Mexico. 
C. OCCIDENTALE. The many flowering stems usually 
decumbent, 5 to 8 inches high, bearing about 3 pairs of 
leaves and all the internodes elongated, the cyme short and 
mostly contracted, 5- to 15-flowered (in more reduced forms 
3-flowered or even 1-flowered); leaves 1 to $ inch long, 
oblong-linear, acutish, ascending, from hirtellous-pubescent, 
with minute subsessile glands interspersed, to nearly glab- 
rous, the stem more notably pubescent with somewhat 
deflexed hairs, but peduncles and pedicels distinctly viscid- 
hirtellous; sterile basal shoots numerous, 2 inches long or 
more (in reduced forms less than 1 inch), their narrowly 
spatulate-linear leaves $ inch long, far surpassing the inter- 
nodes: sepals 23 lines long, scarious at the acute tips and 
more or less so marginally, the back viscid-puberulent and 
only faintly 1-nerved: petals twice the length of the sepals:
