STANDLEY—STUDIES OF TROPIGAL AMERICAN PHANEROGAMS. 483 
abruptly acute at the base, with ‘a short acute triangular beak at the apex, 
undulate-margined ; wings oblong, obtuse, about equaling the keel; stamens 10, 
9 of the filaments adnate for nearly half their length, the tenth free nearly 
to the base; ovary tomentulose. 
Type in the U. S. National Herbarium, no. 678761, collected at San Cristébal 
de Candelaria, province of Cartago, Costa Rica, altitude 1,700 meters, by 
C. Wercklé (H. Pittier, no. 3693). 
Similar to Hrythrina americana Mill. in the form of the flowers, but differing 
in the short calyx, slender branches, and narrow leaflets. The leaflets are much 
narrower than those of any other American species, 
Dolicholus pittieri Standley, sp. nov. 
Stems twining, stout, woody, the younger ones terete, densely viscid-tomentose 
with short yellow hairs; stipules lanceolate, acute, 4 to 5 mm. long, densely 
tomentose, soon deciduous; petioles 2 to 38 cm. long, densely viscid-tomentose ; 
stipelle 2 mm. long, subulate; petiolules about 2 mm. long; leaflets oblong or 
oblong-lanceolate to ovate, 40 to 65 mm. long, 22 to 33 mm. wide, abruptly acute, 
rounded to subcordate at the base, dull green, thick and subcoriaceous, glandular 
on the upper surface and softly pubescent with fine short hairs, conspicuously 
reticulate-veined beneath and abundantly tomentose with short tawny hairs; 
racemes axillary, stout, 12 to 17 cm. long, the rachises densely viscid-tomentose, 
the few flowers rather distant; bracts decidous, lanceolate, shorter than the 
buds; calyx about 2 mm. long, about equaling the corolla, the lobes linear or 
linear-lanceolate, attenuate, the lowest much longer than the others, all several 
times longer that the short campanulate tube, the whole calyx densely glandu- 
lar-pubescent; corolla pale yellow, the banner obovate, emarginate, glabrous, 
the keel and wings of about the same length; legume 3 to 4 cm. long, 1 cm. 
broad, straight along the upper suture, curved below, broadest toward the apex, 
acute, short-beaked, glandular and viscid-hirsute with tawny hairs; seeds 2, 
mature ones not seen. 
Type in the U. 8. National Herbarium, no. 530856, collected around Calf, 
western side of Cauca Valley, State of Cauca, Colombia, altitude 1,000 to 1,200 
meters, December, 1905, by H. Pittier (no. 668). 
In general appearance this is similar to Dolicholus discolor (Mart. & Gal.) 
Rose, a plant of Guatemala and southern Mexico. It differs in its viscid pubes- 
cence, narrower and longer calyx lobes, and glabrous banner. 
TWO NEW SPECIES OF LEIPHAIMOS. 
Leiphaimos, better known by the name Voyria, is a remarkable 
genus of the Gentianaceae which might well be taken as the type of 
a distinct family, as has been suggested. The plants differ from 
other Gentianaceae in being colorless parasites whose leaves are re- 
duced to scales. A large number of species are known from the 
humid forests of northern South America and a few from tropical 
North America. 
Leiphaimos costaricensis Standley, sp. nov. 
Stems slender, succulent, terete, glabrous, erect, simple, T to 18 cm. high, 
one-flowered; cauline scales 4 or 5 pairs, distant, 5 to 6 mm. long, connate for 
about one-third their length, narrowly oblong, acute, subulate-tipped, glabrous ; 
calyx subtended at the base by a pair of connate scales similar to the cauline 
ones, or the flowers sometimes short-pedunculate; calyx 7 mm. long, cleft one-
