298 PITTONIA. 
ł to 3 inch long: calyx 24 lines long, the sepals very acute, 
the outer scarious at tip, the inner with broad scarious mar- 
gin as well as tip, all more or less strigose-pubescent and 
` distinctly I-nerved: corolla rather large, twice the length 
of the calyx or more: capsule not seen. 
Foothills of the Rocky Mountains near Fort Collins, Col- 
orado, 7 May, 1896, C. F. Baker; species with very charac- 
teristic calyx. 
C. ErFusuM. Slender stems loosely tufted, ascending, 8 to 
10 inches long, the rather ample cyme short-peduncled: 
leaves of main stem # inch long or less, 1} lines wide below 
the middle, minutely glandular-hirtellous above, glabrous 
beneath, even as to the prominent midvein, those of the 
sterile shoots an inch long, narrowly spatulate-linear, gland- 
ular-hirtellous above, sparingly so beneath, but midvein 
almost or altogether glabrous; pubescence of stems and 
pedicels more strong and more notably glandular: calyx 2 
lines long, the sepals very acute, obviously 1-nerved, some- 
times with traces of two other nerves, the pubescence short, 
gland-tipped and spreading: petals large, of rather more than 
twice the length of the sepals: capsule straight, seldom sur- 
passing the calyx by half the length of its teeth. 
The typical material of this is of my own collecting in - 
wild grassy pasture land along Dale Creek, Wyoming, 1 
July, 1896. While manifestly allied to C. angustatum, it 
differs very markedly by its more slender habit, glandular 
pubescence, and short straight capsule. 
. C. scoputorum. Loosely tufted perennial, the main stems 
4 to 8 inches long, bearing 2 or 3 remote pairs of linear 
lanceolate leaves and a contracted few-flowered cyme, the 
leaves almost glabrous above, but with scattered small
