78 LEAFLETS. 
acutish blade tapering toa long and broadly winged petiole; 
flowers on stout pedicels, one in the axilof each bract: sepals 
lanceolate, acute or acuminate, of scarcely more than half the 
length of the corolla, this 5-parted, the lobes oval or oblong- 
obtuse, much exceeding the short stout-subulate filaments, their 
glands with a laciniate margin, some or all the laciniæ slenderly 
setaceous-pointed; color of corolla blue-purple but not dark: 
seeds broadly winged. 
Crabtree Meadows, at 11,000 feet, 18 Aug., 1904, Culbertson; 
these specimens in fruit. The flowering specimens used in 
making the diagnosis are Coville & Funston’s n. 1629 of the 
Death Valley Expedition. 
CASTILLEIA TRISECTA. Stems tufted on a tap-root, erect, 
simple, a foot high, loosely leafy, the whole herbage sparsely 
pubescent and somewhat clammy, light-green : leaves about 12 
inches long, of a broadly linear or quadrate undivided portion 
terminated by 3 narrowly linear unequal segments, the middle 
one largest: spike lax, its trifid bracts scarlet: calyx deeply cleft 
on the upper side, the 4 short subequal lobes scarlet: corolla 
with only the long straight ascending galea exserted. 
Hacketts Meadows, at 8,600 feet, 18 July; Baker’s n. 4431. 
Allied to Nuttall’s C. augustifolia, but with different foliage, 
and flowers rather more like those of C. Linaritfolia. 
CASTILLEIA CULBERTSONII. Slender subalpine perennial, the 
stems not tufted, each from its own very slender horizontal 
rootstock, erect, 4 to 6 inches high, both stem and small nar- 
rowly lanceolate acuminate entire leaves minutely and sparingly 
hirtellous: spike short but flowers rather large; bracts trifid, 
the lowest green and leaf-like, the others red-purple; calyx 
villous, unequally cleft, the teeth shorter than the tube: galea 
of the corolla prominent, but shorter than the tube. 
Crabtree Meadow, at 11,000 feet, near Mt. Whitney, 17 Aug., 
Culbertson. In a stouter and more pubescent state the plant 
occurs in U.S. Herb. as collected by Hall & Chandler at 10,000 
feet in the mountains of Fresno Co., July, 1900, the label bear- 
ing the name C. Zemmoni, which species differs widely from 
this in habit, its stems being tufted upon the subligneous crown 
of a tap-root.
