PITTIER—PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 247 
Persoon’s characterization of his C. alternifolium applies almost equally to 
my nos. 4002 and 6607. The former, however, is glabrous or almost so and 
well characterized besides by the glandular dots covering the ovaries and 
branchlets, a detail which would hardly escape observation. On the other hand, 
the climatic conditions of the district where the specimens of the latter number 
were collected resemble more those of Cartagena, the original locality of 
Persoon’s species. Consequently, I refer to this my no. 6607, while no. 4002 
is made the type of a new species. I have not seen Seemann’s specimens. 
Combretum epiphyticum Pittier, sp. nov. 
A trailing vine, the upper branchlets terete, grayish-puberulous, the younger 
growth ferruginous-pubescent. Leaves opposite, coriaceous, the petioles 5 mm. 
long, ferruginous-pubescent, the blades orbicular or ovate, rounded and nar- 
rowly emarginate at the base, rounded-obtuse and often emarginate or mucro- 
nate at the apex, 5 to 13 cm. long, 4.5 to 7 cm. broad, glabrous except on the 
ferruginous-pubescent costa above, reticulate and sparsely hairy on the costa, 
veins, and venules beneath. Inflorescences paniculate at the ends of the branch- 
lets, the rachis ferruginous-pubescent, the branchlets opposite, subtended by a 
small leaf at the base of the panicle, by a lanceolate, caducous bract 3 to 4 
mm. long farther up. Flowers sessile, sweet-scented; bractlets subulate, red- 
dish, hairy, nearly 2 mm. long; calyx broadly campanulate, 4-toothed, about 2 
mm. long, sparsely pubescent without and within; petals 4, sessile, broadly 
ovate or suborbicular, 0.7 to 0.8 mm. long, 1 to 1.2 mm. broad, white, glabrous; 
stamens 8, glabrous, 4 opposite the calyx teeth and inserted at the margin of 
the dise, 4 opposite the petals and inserted a little higher on the calyx limb, 
the filaments 2 to 2.2 mm. long, subulate, the anthers ovate; disc thin, dark 
brown, adnate to the calyx, glabrous; ovary inferior, ovoid, about 1.5 mm. long, 
densely fulvous-hairy; style glabrous, subulate, longer than the stamens. 
Type in the U. S. National Herbarium, no. 716878, collected at Caflo Que- 
brado, Canal Zone, Panama, growing on dead tree in lake, flowers, October 31, 
1914, by H. Pittier (no. 6819). 
Collected also at the type locality, June 14, 1914, Pittier 6668, and near 
Gattn, Canal Zone, in swamps, flowers, March 9, 1860, Hayes 7. 
This species is characterized by the pubescence, the reddish bractlets, the 
sessile petals, and the long, fulvous indument covering the ovary. It is closely 
allied to Combretum jacquini Griseb., differing mainly in the shape of the petals 
and in the hairiness of the leaves and ovary. 
Combretum nicoyanum Pittier, sp. nov. 
A climbing vine, the branchlets terete, glabrous or glabrescent, the young 
growth grayish-pubescent. Leaves coriaceous, opposite or subopposite, the 
petioles densely brownish-hairy, 6 to 8 mm. long, the blades ovate or obovate, 
rounded at the base, more or less abruptly acuminate at the apex, 4.5 to 
9.5 cm. long, 3 to 4.5 em. broad, at first ferruginous on both sides, later glabrous 
or glabrescent above, reticulate and puberulous beneath, principally on the 
costa and veins. Inflorescence terminal, paniculate, loose, the rachis densely 
brownish-pubescent, the branchlets slender, opposite, subopposite, or in whorls 
of 8, subtended at the base by small leaves, further up by lanceolate, caducous 
bracts about 4 mm. long; flowers subsessile, each provided with a subulate, 
caducous bractlet shorter than the ovary; calyx cuplike, 5-toothed, about 2 
mm. long, pilosulous without, barbellate within at the insertion of the stamens ; 
petals 5, sessile, obovate, rounded or emarginate at the apex, 2 to 23 mm. 
long, 0.9 to 1.2 mm. broad, white, minutely hairy and ciliate; stamens 10, the 
5 opposite the petals inserted higher than those opposite the calyx teeth, the 
filaments long and twisted, the anthers ovate; disc tubular; ovary linear,
