14 New Plants. [ZOE 
twisted white hairs, the lamellz unite below into the two glabrous 
tubes which extend nearly to the base of the lobes; filaments purple 
at very base, separate, and surrounded at base by scanty hairs; style 
short and subulate; stigma very small; pod lanceolate or oblong- 
ovate, acuminate, flattened but doubly convex; seeds elongated- 
oblong, marginless. 
Collected by me June 19, 1890, on the Buckskin Mountains 
(Kaiba Plateau), on the southern edge of Utah. It grows in the 
valleys also and in poor soil, in very dry situations. The descrip- 
tions of allied species in the Synoptical Flora are very incomplete 
and unsatisfactory. 
CERCOCARPUS ARIZONICUS. Low, intricately branched, spines- 
cent, I to 2feet high; whole plant short-woolly except the old stems 
which are smooth and very light gray; leaves in fascicles of 6 to 10, 
narrowly oblong and entire, revolute and so broadly linear, very 
thick, obtuse, 3 to 6 lines long and 1 line wide or more; flowers 4 
lines long and the limb 3 lines wide ; seed 2 lines long, covered with 
very long yellowish hairs; tail 1 inch long and very long-hairy. 
Collected June 41, 1890, at Willow Springs, on the cliffs. 
_ Compared with C ledifolius var. intricatus Jones (C. intricatus 
Watson), the flower is twice as large and the tail not much over 
half as long, stouter and the hairs double the length of the var. 
The leaves are several times thicker, shorter; the dense pubescence 
stands straight out from the leaf and is woolly, not at all silky nor 
appressed ; the stems are weakly spinescent, while the var. is not at 
all spinescent. I have long ago shown that Watson’s C. intricatus 
is only a starved form of ledifolius, and all sorts of transitional forms 
are to be found in the Wasatch. Compared with C. éreviflorus 
Gray, this plant has narrow and not at all spatulate leaves, the base 
if anything being a little broader than the tip, leaves woolly instead 
of silky-puberulent, tube of the flower much longer, solitary, other 
differences of fruit not determinable. : 
CYMOPTERUS MEGACEPHALUs, Acaulescent from a thick fusi- 
form root the top of which is shaggy with dead petioles; leaves 
many, flat on the ground, petioles 1 to 4 inches long (an inch or so 
long above the ground), leaves twice to thrice pinnatifid, triangular 
or ovate in outline, blade 3 to 6 inches long, segments bluntly 
toothed or lobed, the teeth reminding one of the lobes of some spe- 
cies of Cheilanthes, leaves thick, glabrous but not glaucous; pedun-
