STANDLEY—TROPICAL AMERICAN PHANEROGAMS. 107 
short and thick, scarcely more than 1 mm. long; calyx tubular-campanulate, 12 mm. 
long, the lobes short, the upper broad and truncate, the lower smaller, ovate, obtuse, 
the whole green, appressed-pubescent; corolla about 25 mm. long, the banner emar- 
ginate, the keel and wings of about the same length, the keel very narrow, strongly 
incurved; legumes oblong-linear, 11 to 14 cm. long, 15 to 18 mm. wide, densely seri- 
ceous with short white hairs; valves keeled along the sutures, and each with 2 longi- 
tudinal keels 1 to 2 mm. high, these about equidistant from the margins and from 
each other; seeds numerous, oval-oblong, 9 mm. long, flattened laterally, dark brown- 
ish or greenish black, more or less splotched with a lighter tint. 
Type in the U. 8. National Herbarium, no. 676590, collected in clearings around 
Alhajuela, Province of Panama, Panama, altitude 30 to 100 meters, January 11 or 12, 
1911, by H. Pittier (no. 2354).

Panama: Vicinity of Penonomé, Williams 132. 
Costa Rica: Nicoya, Pittier. 
Readily distinguished from the other Panamanian species by the 2 keels of each valve 
of the legume. The only other species with similar fruit is Canavalia acuminata 
Rose,’ which has larger legumes, differently shaped seeds, and thin, glabrous leaflets 
of very different outline. That species is known only from Manzanillo, Mexico. 
Dolicholus angulatus Standley, sp. nov. 
Stems twining, the young ones stout, sharply 3-angled, very densely tomentose 
with short, soft, straight, whitish or tawny hairs; stipules persistent, large, 7 to 15 mm. 
long, ovate or oblong-ovate, rounded to rather obtuse, sessile, foliaceous, finely paral- 
lel-nerved, densely tomentose; petioles stout, angled, densely villous or tomentose, 
4 to 6 cm. long; petiolules very stout, about 4 mm. long; stipellee subulate, equaling 
the petiolules; leaflets broadly ovate or rounded-ovate, 35 to 80 mm. long, abruptly 
short-pointed, entire, rounded at the base, bright green, abundantly sericeous on the 
upper surface, beneath densely soft-pubescent and sparingly gland-dotted, the ter- 
minal leaflet larger than the lateral ones, the latter somewhat inequilateral; racemes 
rather slender, 10 to 15 cm. long, the rachises angled, tomentose, the flowers numerous, 
sometimes remote and subverticillate; bracts soon deciduous, lanceolate or lance-oval, 
abruptly long-acuminate, shorter than the calyx; pedicels stout, very short, 1 to 2 mm. 
long; calyx 1 cm. long, slightly accrescent in age, the lobes several times longer than 
the very short tube, subequal, lanceolate, acuminate, 3 mm. wide or less, glabrous or 
sparingly pubescent within, densely tomentose outside, conspicuously pinnate- 
nerved; corolla yellow, slightly shorter than the calyx; standard ovate, rounded at the 
apex, short-clawed, with very small rounded auricles, glabrous; wings and keel of 
about the same length as the standard, the keel somewhat incurved; mature fruit not 
seen, the very young legume densely pubescent along the margins, gland-dotted, 
2-ovuled. 
Type in the U. 8. National Herbarium, no. 676693, collected along the railroad 
between Miraflores and Pedro Miguel, Canal Zone, Panama, altitude 30 to 50 meters, 
January 21, 1911, by H. Pittier (no. 2510). 
This is related to D. reticulatus, but differs conspicuously in the large, persistent 
stipules, the glabrous banner, and the broader calyx lobes. 
Dolicholus ixodes Standley, sp. nov. 
Perennial from a slender or sometimes woody root; stems rather stout, terete, erect 
or twining, densely glandular-hirsutulous; stipules lanceolate, 4 to 5 mm. long, acute, 
rather persistent, brown, with few’ parallel nerves, sparingly pubescent; petioles 
slender, 12 to 18 mm. long, densely viscid-hirsutulous and glandular; petiolules about 
1 mm. long; leaflets ovate-triangular, 10 to 25 mm. long, 11 to 20 mm. broad, acute or
