oct. 4, 1923 STANDLEY: NEW PLANTS FROM SALVADOR 367 
beneath on the nerves; petioles short (2-4 mm.), not winged, hirsute; in- 
florescence unknown. 
Type in the herbarium of the University of Illinois, collected on the 
Voledn de San Salvador, Salvador, in moist forest, altitude about 1800 meters, 
April 7, 1922, by Paul C. Standley (no. 22894). 
Piper uncatum Trelease, sp. nov. 
A practically glabrous shrub with the general characters of P. marginatum 
but the subciliate leaves concavely truncate at base and with the margins 
subconfluent across the petiole, and with rather slender spikes 2-3 mm. thick 
and 150 mm. long, abruptly hooked below the middle. 
Type in the herbarium of the University of Illinois, collected at Tonacate- 
peque, Departamento de San Salvador, Salvador, December 30, 1921, by 
Paul C. Standley (no. 19435). 
Piper uncatum levyanum Trelease, var. nov. 
Differing from the type in having the upper surface of the leaves and the 
veins beneath more or less persistently hairy. 
Type in the Copenhagen Herbarium, collected at Granada, Nicaragua by 
Lévy (no. 1294). Baker 850 from the same locality also represents the same 
variety. 
Ficus rensoniana Calderén & Standl., sp. nov. 
Young branchlets brownish, densely fulvous-pilose; stipules ovate-oblong, 
1.5-2 em. long, acute or acuminate, rather tardily deciduous, thin, brown, 
densely pilose outside below the middle; petioles stout, 1-2.5 em. long, densely 
pilose; leaf blades oval or oblong-oval, broadest at or near the middle, 7—10.5 
em. long, 4-6 em. wide, cordate at base, rounded or very obtuse at apex, 
coriaceous, short-pilose above, especially along the nerves, copiously short- 
pilose beneath with white hairs, the lateral nerves prominent, 6 or 7 pairs, 
arcuate-ascending, distant, anastomosing near the margin; peduncles gemi- 
nate, stout, 4-6 mm. long; involucre bilobate, 10-12 mm. long, the lobes 
rounded, thin, brown, strigose near the base, glabrous within; receptacles 
globose, 8-11 mm. in diameter, glabrous, the ostiole prominent, closed by 3 
rounded scales. 
Type in the U. S. National Herbarium, no. 1,152,090, collected at San 
Salvador, Salvador, August, 1920, by Dr. Salvador Calderén (no. 1120). 
Most closely related, apparently, to Ff’. pringlei 8S. Wats., which is distin- 
quished from the Salvadorean tree by its dense pubescence, larger receptacles, 
and sericeous involucres. 
Aristolochia salvadorensis Standl., sp. nov. 
A large woody vine, the branches densely brownish-puberulent, with 
very short internodes; petioles stout, densely puberulent, 5-7 mm. long; leaf 
blades oblong, often slightly wider above the middle, 11-20 em. long, 4-9 cm. 
wide, acute or abruptly short-acuminate, rounded at base, thick, glabrous 
above, with prominulous venation, beneath lustrous, puberulent along the 
nerves, 5-nerved from the base and with several pairs of lateral nerves, the 
veins very prominent and reticulate; racemes large, branched, borne at the 
base of the stem, the rachis densely brown-pilose with short hairs, often 
geniculate, the bracts ovate or lanceolate, 12 mm. long or less, sometimes 
green and foliaceous, the pedicels mostly 5—7 em. long, slender; bractlets none
