WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXICO. 135 
MIMOSACEAE. 
Morongia occidentalis Wooton & Standley, sp. nov. 
Stems prostrate, stout, striate, densely and finely puberulent, armed with 
very few, distant, recurved prickles; leaves bipinnate, with 5 or 6 pairs of 
pinne; petioles slender, about 4 cm. long, striate, finely puberulent, armed 
with few stout prickles; leaflets oblong, about 4 mm. long, acute or acutish, 
thick, smooth, not nerved, glabrous or nearly so; flowers pink, in dense heads; 
calyx glabrous or nearly so, the thin lobes ovate, acute; peduncles 2 to 6 cm. 
long, puberulent, with few weak prickles or none; pods slender, 7 to 9 cm. 
long, 2 or 3 mm. wide, flattened, armed on the sides with long, slender, sparingly 
puberulent prickles, usually naked on the margins or with prickles of the same 
kind as on the sides, narrowed at the base, bearing at the apex a stout beak 
5 to 7 mm. long. ° 
Type in the U. 8. National Herbarium, no. 660612, collected near Nara Visa, 
July 4, 1911, by Mr. Geo. L. Fisher (no, 190). Also collected near Nara Visa, 
August 17, 1910, by Mr. Fisher (no. 58). 
Most closely allied, perhaps, to M. angustata, but distinguished by the flat, 
puberulent pods armed with but few prickles, and by the few prickles of the 
abundantly pubescent stems. 
CAESALPINIACEAE. 
Chamaecrista rostrata Wooton & Standley, sp. nov. 
A slender annual, 20 cm. high or less, simple at the base, sparingly branched 
above; stems herbaceous, reddish, puberulent; leaflets 10 or 12, narrowly ob- 
long, rounded at the apex, very shortly mucronulate, 8 or 10 mm. long, glabrous ; 
petiolar gland oblong, small, short-stipitate ; stipules linear-lanceolate, long- 
attenuate; peduncles few, supra-axillary, arcuate, 1-flowered; petals bright 
yellow, 12 mm. long; sepals one-half to two-thirds as long as the petals, 
lanceolate, membranaceous; pods 25 to 35 mm. long, 5 mm. wide, appressed- 
pubescent, ending in a beak 2 to’3 mm. long. 
Type in the U. S. National Herbarium, no. 660032, collected in sandy soil 
at Logan, October 5, 1910, by Mr. Geo. L. Fisher (no. 93). 
While related to C. fasciculata, this may be readily distinguished by the 
long beaks of the pods, the fewer leaflets neither acute nor conspicuously 
mucronate, the 1-flowered peduncles, and the shorter sepals.
