312 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
8mm. long, the lateral lobes somewhat falcate, the upper lobe broad and retuse, much 
shorter than the others; corolla large, 2.5 em. long, ‘‘ dark purple;’’ ovary glabrous 
or nearly so, linear. 
Specimens examined: 
Oaxaca: Near Santo Domingo, altitude 480 meters, I. W. Nelson, June 18, 1895 
(no. 2692), and Santa Efigenia, altitude 150 meters, EK. W. Nelson, July 18, 
1895 (no. 2848, type). 
Phaseolus occidentalis Rose, sp. nov. 
A high-climbing vine; branches becoming glabrate; leaflets broadly ovate to 
orbicular, 5 to 10 em. long, round at base and apex, slightly hairy on both. sides, 
prominently veined beneath; racemes including the peduncle elongated, often more 
than 3 dm. long, bearing mature pods, flowers, and young buds at the same time; 
pedicels short; bracts subtending the flowers ovate, obtuse, glabrous, nerved; calyx 
reticulated, nearly glabrous; calyx tube 4 mm. long; the lateral and lower sepals 
about the length of the tube, narrow; upper lobe broad and retuse; corolla violet, 
2.5 em. or more long, glabrous; pods 7 to 10 cm. long, narrow; seeds 6 mim. in 
diameter, tan-colored mottled with black. 
Collected by J. N. Rose in canyons near the little town of Acaponeta, Territorio 
de Tepie, June 25, 1897 (no, 1468). 
This species differs from the original description of P. trwcillensis in the shape of 
the leaflets, and from all our named herbarium material, in its glabrous banner, in 
size and color of seeds, ete. 
Palmer’s no. 158 from Acapulco must be near this species, but the leaflets are often 
linear. 
Frank Lamb’s no. 499 is much nearer to it and, coming as it does from near the 
same locality, is probably to be definitely referred here, It was distributed as 
P. speciosus, 
NEW SPECIES OF SEVERAL GENERA. 
Aeschynomene pringlei Rose, sp. nov. 
A slender shrub 2.5 to 3.5 meters high; bark of old branches nearly black and 
glabrous, of young branches light-colored and densely silky-pubescent; leaves nar- 
row and elongated; stipules caducous, not seen even on flowering branches; leaflets 
5 to 12 pairs, narrowly to broadly oblong, obtuse or rounded at apex but with a 
decided mucro, silky pubescent on both sides when young, glabrate above in age, 
paler and reticulated beneath; inflorescence paniculate, more or less leafy; branches 
few-flowered, pubescent; bracts at base of calyx orbicular, rounded at apex; calyx 
two-lipped, the upper lip retuse, the lower 3-lobed, the lateral lobes obtuse and 
shorter than the middle one; banner orbicular, purplish; stamens divided into two 
clusters of 5 each; ovary stipitate, clothed with long silky hairs; stipe slender, 5 to 7 
mm. long; pods 2 or 8-jointed; joints oblong, 7mm. long, pubescent, dull, slightly 
reticulated, the lower one curved at base, the other rounded. 
Collected by C. G. Pringle at Jojutla, Morelos, August 80 and October 28, 1902 
(no, 8709).
