pubescent ; lateral nerves, including the basal pair, 5 or 6 on each 
side of the midrib, prominent, rather sharply ascending, nearly 
straight ; petioles about 1 cm long ; panicles axillary and terminal, 
in fruit about 8 cm long, densely pubescent with short brownish 
hairs. Fruits subreniform, 2-celled, base truncate, apex slightly 
apiculate, compressed but at the same time distinctly inflated, 
about 1.5 cm long, 2 to 2.5 cm wide, the valves coriaceous densely 
and softly pubescent with shining brownish hairs of two types, 
short, rather densely matted ones, intermixed with very numer- 
ous, long, appressed-spreading, shining ones. Seeds 1.5 to 2 mm 
long, with numerous, long, shining, pale hairs. 
Leyte, Buenavista, near Jaro, C. A. Wenzel 837, June 5, 1914, in forests, 
altitude about 500 m. 
A species characterized by its leaves which are entirely or nearly glabrous 
above and comparatively slightly pubescent beneath, and its 2-valved, com- 
pressed, densely pubescent fruits which are distinctly inflated. It may 
belong in the genus I have previously designated as Halconia, which, per- 
haps, should be merged with Trichospermum.

usque ad 12 cm longis, acutis vel leviter acuminatis, basi

apex acute or somewhat acuminate, base rounded to subacute, 
margins sometimes slightly decurrent along the petioles, the 
lower surface puncticulate ; lateral nerves 11 to 13 on each side 
of the midrib, very prominent; petioles 1.5 to 2 cm long. Pani- 
cles terminal, ample, 20 to 25 cm long, sparingly appressed-
