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.

Frutex vel arbor, partibus junioribus inflorescentiisque excep- 

 tis glabra ; f oliis 1-f oliolatis, foliolis chartaceis, olivaceis vel brun- 

 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.
