inconspicuous superficially, veins about 4—7 on each side, elevat- 

 ed on both surfaces when dried, erect-patent; veinlets angulate- 

 ly anastomosing ; petiole semiterete, shallowly canaliculate 

 in front, glabrous, green but deeper towards the base, 1— 23cm. 

 long ; stipules very minute, placed on the lateral sides at the 

 base of the petiole, linear-subulate, caducous, brown. Cyme 

 small, equal to or exceeding the petiole in length, lateral, 

 axillary, usually opposite, 1— 4— dichotomously branched, 2 

 (normally 3) to 31 flowered ; peduncle erect-patent or spread- 

 ing, terete but often subangulate, when dried angulate as 

 are pedicels, green, 5—12 rarely 17mm. long ; bracts small, 

 opposite, thick, carinate dorsally, green, deltoid-subulate but 

 those under the flower ovate and obtuse, entire, ciliato-denticu- 

 late, li-2mm. long ; pedicels short, opposite, erect-patent, 

 green, the extreme ones very short and much shorter than the 

 flowers. Flowers regular, small, viridescent or pale-viridescent, 

 crowded, articulated to the apex of the pedicel, odoriferous, 

 about G-8mm. across in the male, and about 6mm. across in 

 the female. Calyx 5- rarely 1- or G-parted, subgloboso-cam- 

 panulate, green, persistent ; segments nearly equal, somewhat 

 shorter in the outer ones, erect, imbricated, semiorbicular, 

 rounded at the apex, thick, ciliated, slightly concave, 1J— 2imm. 

 long in the male flowers but 1-llmra. long in the female. 

 Petals 5 rarely 4 or 6, nearly equal, widely infundibuliform 

 together, patent above, alternate with the calyx-segments, 

 exceeding the calyx, inserted at the back under the edge of the 

 disk, sessile, thickish, with loose veins, deciduous, rounded- 

 obtuse, oval and entire in the outer ones but the inner ours 

 oval-elliptical, sinuato-entire, often minutely crenulato-dcnticu- 

 latc .'it the apex. Stamens 5 rarely 4 or 6, equal, alternate 

 with the patals and much shorter than them, inserted 00 the 

 back under the edge- of the disk; filaments linear-subulate, 

 incurved, slightly flattened, somewhat Longer than the anther ; 

 anther broadly ovate, bifid at both ends, introrse, dorsifixed, 

 2— locular, dehiscence longitudinal, about 1 j .mm. long; locula- 

 ments oblong; pollen yellow, oblong, 3 sulcate longitudinally;
