-STANDLEY—STUDIES OF TROPICAL AMERICAN PHANEROGAMS. 431 
Phaseolus stenolobus Standley, sp. nov. 
Stems slender, twining, pilose with reddish brown hairs; stipules persistent, 
not produced at the base, lanceolate, acute, 3 to 4 mm. long, conspicuously paral- 
lel-nerved, pilose; petioles slender, 4 to 8 cm. long, pilose; stipelle minute; 
petiolules 3 mm. long or less; leaflets thin, rhombic-ovate to triangular-oblong, 
6 to 11 cm. long, 3.5 to 7 cm. wide, acuminate, rounded or obtuse at the base, 
abundantly pubescent on the upper surface with long, very slender, appressed 
hairs having bulbous bases, softly pubescent beneath with similar hairs; pe- 
duncles 16 to 22 cm. long, pilose, the racemes short, few-flowered, nodose; bracts 
lance-linear or lanceolate, 9 to 12 mm. long, deciduous; pedicels 4 mm. long or 
less; calyx about 12 mm. long, sparsely pilose, the tube broadly campanulate, 
3 mm. long, the upper lobe very short, shallowly emarginate, the 3 lower lobes 
linear, acute, 2 or 3 times as long as the tube; corolla segments about 3 cm. 
long, glabrous, subequal, the keel several times spirally coiled; style abundantly 
bearded above; fruit not seen. 
Type in the U. S. National Herbarium, no. 355066, collected at Cerro Redondo, 
Department of Santa Rosa, Guatemala, altitude 1,500 meters, October, 1893, by 
Heyde and Lux (J. D. Smith, no. 6135). 
Differing from the preceding species in the narrow calyx lobes, narrow bracts, 
and the different pubescence of the leaflets. 
Chamaecrista macropoda Standley, sp. nov. 
Stems probably prostrate, stout, abundantly setose and cinereous, copiously 
leafy ; stipules lanceolate or ovate-lanceolate, about 12 mm. long, rather abruptly 
attenuate, aristate-tipped, obliquely rounded at the base, appressed to the stems, 
strongly nerved, setose on the margins; leaf rachis 2 to 3 cm. long, subulate- 
appendaged above the uppermost pair of leaflets, the lowest pair of leaflets 
borne near the base; petiolar gland very small, short-stipitate; leaflets 3 to 5 
pairs, rather firm, narrowly oblong, 10 to 20 mm. long, 3.5 to 5 mm. wide, obtuse, 
aristate-tipped, obliquely rounded at the base, glabrous or sparingly ciliate, con- 
spicuously pinnate-veined, the midvein excentric; flowers solitary or 2 in each 
axil; pedicels 20 to 837 mm. long, ascending, slender, glabrous, bearing a pair of 
small linear-subulate bracts near the apex; sepals 6 to 7 mm. long, thin, oblong- 
lanceolate, acute, subulate-tipped, glabrous or sparingly setose; petals about 8 
mm. long; legumes 35 to 45 mm. long, 4.5 mm. wide, abruptly acutish, the beak 
about 1 mm. long, minutely appressed-pubescent, 10 to 12-seeded. 
Type in the U. 8. National Herbarium, no. 258959, collected on the Cerro Re- 
dondo, Department of Santa Rosa, Guatemala, altitude about 1,400 meters, in 
September, 1893, by Heyde and Lux (J. D. Smith, no. 61383). 
Originally distributed as Cassia grammica Spreng., a South American species, 
the determination by Micheli. That species, however, has pubescent leaflets and 
Jarger flowers, and the leaflets are smaller and of different form. The Guate- 
malan plant is related to Chamaecrista pilosa and C. serpens ; from the former 
it differs in having petiolar glands and from the latter in its larger, glabrous 
leaflets, much larger, broader stipules, and elongated, many-seeded legume. 
Calliandra mollis Standley, sp. nov. 
Stems herbaceous, erect or ascending, stout, branched, abundantly villous 
with tawny hairs; stipules triangular-ovate or triangular-lanceolate, acute, 5 to 
7 mm. long, striate, pilose; rachis of the leaves 50 to 65 mm. long, villous with 
tawny hairs; pinne 4 to 6 pairs, 25 to 55 mm. long; leaflets 7 to 22 pairs, 
approximate, narrowly oblong, 8 to 18 mm. long, 2.5 mm. wide, obtuse, apiculate, 
oblique at the base, densely pilose with white hairs on both surfaces; inflo- 
rescence of terminal or axillary racemes, each of several or numerous heads; 
peduncles slender, 15 to 32 mm. long, densely villous with tawny hairs; bracts
