37- CASALPINIA repens n. sp. Perennial, 9 to 13 cm. high, 
from slender, woody, creeping rootstocks; leaves and peduncles 
crowded on a short stem, canescent with short, curled hairs; 
leaves with from 5 to 7 pinnee, leaflets 4 to 6 closely appressed, 
nerveless, with a few scattered, depressed glands varying in 
shape, usually irregular in outline (many leaflets are without 
the glands); stipules ovate-acuminate, petioles ribbed, a little 
longer than the blade, with several long, lax bristles where the 
pinnze join the axis, and one at the base of each leaflet; pedun- 
cles stout, ribbed, surpassing the leaves, covered closely with the 
short, white hairs, and with occasional longer ones similar to the 
lax bristles on the leaves; flowers at first erect, closely clustered, 
pedicels becoming deflexed and distant in the fruiting, elongating 
raceme; four upper sepals lanceolate, lowest oblanceolate, cov- 
ered with longer white hairs than the rest of the plant; without 
glands, as is also the corolla; petals surpassing the sepals, obo- 
vate, tapering to the short claw, 8 to 12 mm. long, 3 mm. broad, 
smooth except the vexillum, which has a broad, hairy claw; 
stamens with filaments about 10 mm. long, broadening at base, 
smooth above, ciliate with blunt, coarse hairs below, densest at 
the base; style cylindrical, broadening at the base, and to a less 
degree at the ciliate campanulate stigma, which is slightly 
hairy below; legume at first canescent with short, curled hairs, 
orbicular to obovate; in age with hairs so scattered that it is 
no longer canescent, becoming reticulate with prominent trans-

orbicular to elliptical and oblong, usually abruptly pointed 
with the persistent style, entirely without glands, 1% to 3 
cm. long, 1% to 2 cm. broad; seeds usually two. ‘This grew 
in sandy soil, and formed loosely-spreading mats. It was col- 
lected in Court House Wash, near where it comes into the Grand 
River, on the opposite side from Moab, in southeastern Utah,
