A shrub or tree, glabrous except the slightly pubescent young- 
er parts. Branches slender, terete, brownish or pale-greenish, 
glabrous, the young branchlets somewhat appressed ferrugi- 
nous-pubescent as are the very young petioles. Leaves dark- 
olivaceous when dry, somewhat shining, glabrous, oblong to 
ovate-oblong, 7 to 11 cm long, 2.5 to 4.5 cm wide, rather prom- 
inently and sharply acuminate, base rounded and usually with 
two, minute, stipellate glands on the upper surface near the 
juncture with the petiole, margins distantly and minutely denti- 
culate; lateral nerves slender, about 12 on each side of the mid- 
rib; petioles 1 to 3 cm long. Pistellate inflorescences axillary, 
10 to 20 cm long, solitary, the flowers few, depauperately fas- 
cicled at the apex or solitary, the long peduncle without leaf- 
like bracts, or with several scattered along the upper one-third, 
or near the apex, the bracts leaf-like, lanceolate to oblong-ellip- 
tic, up to 1.6 mm long, persistent. Pedicels about 5 mm long, 
in fruit exceeding 1 cm in length. Sepals oblong, obtuse or 
slightly retuse, about 4 mm long and 1.5 mm wide, in mature 
fruit about 6 mm long and 2.2 mm wide, free or nearly so, per- 
sistent. Petals 5, glabrous, free, broadly spatulate, 5 mm long, 
2 mm wide, much narrowed in the lower two-thirds. Disk- 
glands truncate, nearly square in outline, 0.5 mm long. Ovary 
ovoid, glabrous, about 1.5 mm long; style very short; divided 
into three parts, the arms bifid. Mature fruit depressed-globose, 
dark-colored, smooth and shining, about 12 mm in diameter, 
composed of three, dry, dehiscent cocci.

It is with some doubt that I have placed this species in Dimorphocalyx, 
as the staminate flowers are as yet unknown. In aspect it distinctly 
resembles Dimorphocalyx longipes Merr., but is not closely allied to that 
species. It is readily distinguishable by its few-flowered, very long-peduncled 
pistillate inflorescence, the flowers borne at the tip of the long peduncle, 
and the presence of leaf-like bracts scattered along - the upper part of the 
peduncle on most of the inflorescences.
