368 FsIOURNAL OF THE WASHINGTON ACADEMY OF SCIENCES VOL. 13, NO. 16 
at base of calyx; ovary about 1.5 cm. long, abruptly curved near the base, 
6-costate, densely brown-pilose; calyx dark brown-purple, about 4.5 em. long, 
sparsely puberulent outside, the tube very short and inflated, the pouch 
inflated, rounded, produced within the limb into a large blunt recurved beak, 
the limb shallowly 3-lobed, the 2 lateral lobes broad, acute, the central lobe 
much smaller and narrower, acute or short-acuminate; style short, the stigma 
obscurely lobate; capsule oblong, about 7 em. long and 2—2.5 cm. in diameter, 
sharply 6-angulate, brown-tomentulose. 
Type in the U. 8. National Herbarium, no. 1,111,203, collected at San 
Salvador, February 9, 1923, by Dr. Salvador Calderén (no. 1484). The 
following additional specimens have been examined: 
SaLvapor: San Salvador, November, 1921, Calderén 287. Santa Tecla, 
August, 1922, Calderén 1096. Sierra de Apaneca, region of the Finca Colima 
Departamento de Ahuachapan, January, 1922, Standley 20036. 
The vernacular names are guaco, guaquito, and guaquito de la tierra. Like 
other species of the genus, it is employed locally as a remedy for snake bites. 
Aristolochia salvadorensis is related to A. arborea Linden, but has very 
different flowers and much smaller, reticulately veined leaves. The leaves 
somewhat resemble those of A. maxima L., which also is abundant in Salvador, 
but the flowers of the two species are quite dissimilar, and even sterile speci- 
mens of the two are easily distinguishable. 
Coccoloba montana Standl., sp. nov. 
Young branchlets terete, pale, glabrous; ocreae brown, glabrous, 6-7 
mm. long; petioles stout, glabrous, 12-20 mm. long; leaf blades ovate or 
oblong-ovate, 10-20 em. long, 5.5-10 cm. wide, acuminate or long-acuminate, 
unequal at base, rounded on one side, on the other semicordate, glabrous 
above, glabrous beneath except along the costa, there brownish-tomentose, 
especially in the axils of the lateral nerves, papyraceous, the costa salient on 
both surfaces, the venation conspicuous above and beneath and closely 
reticulate. 
Type in the U.S. National Herbarium, no. 1,135,924, collected in the 
Sierra de Apaneca, region of the Finca Colima, Departamento de Ahuachapan, 
Salvador, January, 1922, by Paul C. Standley ( no. 20061). 
The vernacular name is papaturro. Although known only from sterile 
specimens, the leaves of this Coccoloba are so distinct from those of the other 
Central American species that it seems desirable to give it a name for purposes 
of reference. 
Pleuropetalum calospermum Standl., sp. nov. 
Slender shrub, 1-2 m. high, the young branches granular-papillose; petioles 
slender, 1-3 em. long; leaf blades oblong-ovate to lance-oblong, 9-13 cm. long, 
3-5 em. wide, long-acuminate, rounded or obtuse at base and abruptly decur- 
rent upon the petiole, thin, bright green above, paler beneath, when young 
obscurely puberulent but quickly glabrate; inflorescences terminal and in 
the upper axils, cymose-paniculate, few-flowered, long-pedunculate, shorter 
than the leaves; pedicels very stout, sometimes 7 mm. long but usually 
much shorter; bractlets rounded-ovate, 1 mm. long; sepals rounded-oval, 
3-3.5 mm. long, rounded at apex, sharply ribbed, glabrous; fruit baccate, 
black, 6-7 mm. broad, globose, glabrous; seeds numerous, on thickened
