NEW OR NOTEWORTHY SPECIES 151 
angular and seabrous-puberulent: leaves mostly 1 to 14 
inches long, the lower lanceolate and notably feather-veined 
with white but rather fine veins; the very numerous rameal 
ones mostly linear, or nearly so, and l-nerved, all quite 
entire and nearly glabrous except along the margin and 
veins, here strigulose: peduncles about 3 inch long, ascend- 
ing in flower, deflexed in fruit: corolla rather small, green- 
ish-yellow, with dark-green spots: fruiting calyx broadly 
and acutely ovate, thinnish, reticulate, glabrous except as to 
the rather shortly and broadly triangular-lanceolate teeth, 
these whitish-puberulent. 
Collected at Piedra, southern Colorado, 12 July, 1899, by 
C. F. Baker; the specimens mostly not well past the early 
flowering. The species is related to what Mr. Rydberg has 
identified, though to my mind not satisfactorily, with P. 
Virginiana; from which it differs greatly in its very many 
small entire leaves, and their conspicuous venation. The 
form of the mature calyx is also in lively contrast with that 
of P. Virginiana, Rydb. 
CASTILLEIA LINEATA. Tufted stems rigid and brittle, but 
not suffrutescent, about a foot high from a perennial root, 
narrowly and not densely spicate for about one-third the 
length ; herbage hoary-tomentose: leaves ascending, linear, 2 
inches long, entire, or in more robust plants with one or more 
pairs of linear segments, all strongly 3-nerved and chan- 
neled and appearing striate: braets similar to the leaves, 
more commonly palmately cleft to the middle into 3 linear 
lobes: corollas greenish and inconspicuous, little exceeding 
the calyx and bracts. 
Moist slopes near Pagosa Springs, southern Colorado, 18 
July, 1899, C. F. Baker. Very distinct from all other Cas- © 
tilleias of the Rocky Mountain region, and not very closely 
allied to the tomentoso species of even Mexico and Cali- 
fornia.
