dry; seeds 1 or 2, compressed, brown, 3 to 3.5 cm long, about 
2 cm wide.

This strongly characterized species is well marked by its few, rather 
large, prominently and laxly reticulate, slenderly caudate-acuminate leaf- 
lets; its laxly reticulate valves; and in being entirely glabrous throughout. 
It differs radically from Crudia havilandi Prain, to which it is apparently 
most closely allied, in its fewer, much larger, more numerously nerved, 
leaflets.

neis, nitidis, oblongo-ellipticis, usque ad 15 cm longis, acuminatis 
ad rotundatis, basi cuneatis, nervis primariis utrinque circiter

A shrub or tree, glabrous except the tips of the branchlets 
and the inflorescences. Branches pale when dry, glabrous, com- 
pressed. Leaves all 1-foliolate, the leaflets chartaceous, oliva- 
ceous or brown when dry, shining on both surfaces, 10 to 15 
cm long, 4 to 7 cm wide, mostly oblong-elliptic, the lower surface 
distinctly glandular-puncticulate, the apex broadly acuminate 
and apiculate to broadly rounded, the base cuneate; primary 
lateral nerves about 13 on each side of the midrib, distinct, 
anastomosing, the reticulations irregular, distinct; petioles 1 to 
2 cm long. Cymes axillary and terminal, 3 to 6 cm long, few- 
flowered, sparingly fulvous- to cinereous-pubescent, the primary 
branches few, 1 cm long or less, each bearing from three to six 
subumbellately arranged flowers at their apices, the pedicels up 
to 4 mm in length. Calyx-lobes pubescent, ovate, obtuse, 0.4 mm 
long or less. Petals sparingly pubescent, oblong-ovate, acute or 
slightly acuminate, about 2.5 mm long. Ovary glabrous. Sta- 
mens 8, the filaments equal.

This is one of the few known representatives of the genus with 
1-foliolate leaves and is manifestly allied to Melicope helferi Hook. f. of 
the Andaman Islands, from which it is distinguished, among other char- 
acters, by its differently shaped, more numerously nerved leaflets and 
pubescent inflorescences and tips of the young branchlets.
