and sharply apiculate; lateral nerves 6 or 7 on each side of the 
midrib, slender, distinct, curved-anastomosing; petioles about 
4 mm long. Flowers axillary, all 6-merous, the upper ones mostly 
pistillate, the lower mostly staminate, sometimes both found in 
the same axil. Male flowers pedicellate, about 4.5 mm in dia- 
meter, the pedicels slender, 4 to 5 mm long. Outer three perianth 
segments ovate, recurved, about 3 mm long, the inner three 
similar, but considerably narrower, rather coriaceous. Anthers 
5, united into a globose mass about 1 mm in diameter. Pistillate 
flowers numerous, crowded in definite peduncled heads, the pe- 
duncles 3 to 4 mm long, flowers 3 or 4 to 10 in a head, their pedi- 
cels 1 to 2 mm long, each head subtended by numerous, oblong, 
acuminate, 1 mm long bracts. Perianth segments 6, oblong- 
ovate, about 2.5 mm long, the inner three somewhat narrower 
than the outer ones. Ovary very densely pubescent, 5-celled, the 
column densely pubescent, stout, cylindric, not constricted at 
the base, slightly narrower than the ovary, densely pubescent, 
the stigmatic portions usually 5, glabrous, the column about 
four times as long as the ovary.

A very characteristic species, easily recognized by its peduncled heads 
of pistillate flowers, its 6-merous flowers, densely pubescent ovary and 
style, the latter cylindric, stout, about four times as long as the ovary. 
In aspect it somewhat resembles the Philippine Glochidion trichogynum 
Muell.-Arg., but is not closely allied to that species, and belongs in an 
entirely different section of the genus.

This species has been previously reported from Pegu to Tenasserim, 
the Malay Peninsula, and Singapore. The Bornean specimen cited above 
presents only male flowers, and agrees closely with Singapore specimens 
collected by Ridley.

The specimen is identical in all respects with the Celebes plant collected 
at Baleh Anjen by Teysmann, mentioned by J. J. S. Smith, 1. c. 168, as 
probably representing an abnormal form of Glochidion kollmannianum. 
The inflorescences on both are somewhat cymose, although some
