 a thin and obtuse wing ; the lower or chalazal end produced into a 

 subulate appendage of equal or greater length. Embryo not seen.

Shrub or small tree (the size not recorded), glabrous, or the slender 

 branchlets and inflorescence obscurely puberulent when young. Sti- 

 pules not seen, probably small and very caducous. Leaves opposite 

 and often verticiUate in threes or fours, or even in fives, about 2 

 inches in length, obovate-elliptical, oblong, or oval, thin, but of a coria- 

 ceous texture, dull, obtuse, entire, contracted at the base into a petiole of 

 3 to 6 lines in length, sparingly pinnately veined ; the veins only 4 or 

 5 pairs, connected by minute reticulated veinlets. Flowers minute, 

 numerous, in rather small and cymose, axillary panicles, which are 

 shorter than the leaves. Peduncles longer than the petioles. Bracts 

 small, deciduous. Pedicels crowded, often fascicled, less than a line 

 long, articulated at the base. Only one kind of flowers seen, which 

 appear to be hermaphrodite. Flower-buds barely half a line in dia- 

 meter, globose. Calyx glabrous, deeply cleft or parted into 4, 5, or 

 rarely 6 triangular-ovate segments, valvate in aestivation. Corolla 

 none. Stamens twice as many as the segments of the calyx, inserted
