490 Eastwoop: New Species oF WESTERN PLANTS 
It is allied to Arabis blepharophylla H. & A., from which it dif- 
fers in shape and size of leaves, almost complete absence of pu- 
bescence, smaller flowers and longer and more slender pods. 
These differences are added to a general dissimilarity in appear- 
ance, so that the two species would never be confused, though the 
flowers have the same color and fragrance. 
“Cleomella nana 
Annual, low, 3-8 cm. high, simple or branching from near the 
base, the branched plants -having a diameter about equal to the 
height ; stems striate with fine broken lines and occasionally verru- 
cose, glaucous: leaves trifoliate, the petioles generally shorter than 
the petiolulate leaflets; stipules tufts of hairs; leaflets narrowly 
oblong-lanceolate, the lateral 6 mm. long, the middle 9 mm., 
2-3 mm. wide, aristate, tapering at base, entire but somewhat 
revolute, midvein distinct, surface (under a good lens) covered 
with minute reticulation: flowers in sessile racemes on spreading 
pedicels 5-10 mm. long ; lowest bracts like the leaves, upper like 
the stipules: calyx of 4 subulate-aristate divisions 1.5 mm. long, 
stipe with a bulb-like swelling at base, deflexed, becoming 6 mm. : 
petals yellow, oval, 4.5 mm. long, 2 mm. wide, obtuse, subsessile : 
stamens surpassing the petals, the filaments 10 mm. long ; anthers 
linear, mucronate, almost 2 mm. long: style 1.5 mm. long, stigma 
2-lobed: capsule when young rhomboidal, later becoming more 
ovate, not winged, minutely reticulated, 5 mm. wide, 4 mm. long: 
seeds 2, yellow-brown, suborbicular, 2 mm. in diameter, flattened, 
the outer coat transparent so that the space between the caulicle 
and the cotyledons is visible and resembles the mouth of a fish. 
This interesting C/eomella was collected by the author, May 24, 
1892, between Thompson’s Wash and Moab, in southeastern Utah. 
It is near C. obtusifolia Torr. & Frém., but differs in habit, flowers, 
and fruit. The strongly-winged fruit of C. obtusifolia presents an . 
entirely different appearance. 
- Wislizenia scabrida 
Annual, erect, branching divaricately from the base and also 
above, 3 dm. or more in height, rather stout, scabrous through- 
out ; stems purplish, ribbed: leaflets 3. or rarely 4, obovate or 
elliptical, glaucous on the lower surface, bright green on the upper, 
retuse and aristate, 2 cm. long, 1 cm. wide, with petiolules 2 mm. 
long ; petioles generally shorter than the leaflets; stipules a tuft 
of bristles : racemes elongating in fruit, corymbose in flower, short-
