lateral nerves about 8 on each side of the midrib, slender, curved- 
anastomosing, the reticulations evident on both surfaces ; petioles 
2 mm long or less, pubescent. Fruits axillary, solitary or in 
pairs, depressed-globose, up to 11 mm in diameter, 2-celled, the 
pericarp crustaceous, sparingly appressed-hirsute ; pedicels 
slender, slightly pubescent, nearly 1 cm long.

ridges, altitude about 80 meters. 
Closely allied to Cyclostemon ellipsoideus Merr., differing in its fewer 
nerved leaves and in its depressed-globose not ellipsoid fruits. 
ENDOSPERMUM Bentham 
ENDOSPERM UM OVATUM sp. nov. § Euendospermum. 
Arbor, ramulis circiter 8 mm diametro, solidis ; foliis coriaceis, 
non peltatis, ovatis, usque ad 14 cm longis, acutis vel leviter 
acuminatis, basi acutis ad late rotundatis, vix cordatis, supra 
glabris, junioribus subtus pubescentibus, vetustioribus glabris, 
ad apicem petioli biglandulosis ; paniculis quam folia brevioribus, 
pubescentibus ; fructibus subglobosis, carnosis, 6 mm longis, 
seminibus 2. 
A tree, size not stated, the branches stout, terete, the ulti- 
mate ones 8 mm in diameter, glabrous, reddish-brown or grayish, 
marked with large petiolar scars, the growing tips pubescent. 
Leaves ovate, coriaceous, 8 to 14 cm long, 5 to 9 cm wide, entire, 
the apex acute or slightly acuminate, the base broadly rounded to 
acute, not cordate, the upper surface glabrous, smooth and shin- 
ing, brownish or olivaceous when dry, the lower surface paler, 
in very young leaves rather softly pubescent with simple hairs, 
in age entirely glabrous, with two prominent glands, one on each 
side at the juncture of the petiole with the lamina, the base 
5-nerved, the lateral nerves above the basal ones about 5 on 
each side of the midrib, very prominent, the reticulations prom- 
inent; petioles 3 to 7 cm in length. Panicles axillary, 10 to 18 
cm long, somewhat pubescent with simple hairs, narrowly pyra- 
midal, the lower branches 5 cm long or less, the upper gradually 
shorter. Flowers not seen. Fruit subglobose, fleshy, yellow, 
about 6 mm long, the seed smooth, broadly ellipsoid, 4 mm long.

August, 1912. 
Evidently a very distinct species but manifestly allied to Endospermum 
borneense Muell.-Arg., of Borneo, from which it differs in its differently 
shaped, somewhat larger leaves which are not all cordate at the base, 
and which are quite glabrous on both surfaces, and its paniculate, not 
racemose inflorescence.
