Ca. 1.5 m tall, green and succulent.  Leaves stipulate, opposite one another or opposite a branch, compound with two obovate, entire leaflets and a tiny projection (rachis remnant?) between them.  Herbage completely glabrous.
(this about half life-size)

Flowers minute, single in the axils of the leaves and branches or single on the sides of the branches.
Developing fruit on pedicel, ca. 2.2 x life size

I have only a few very small (ca. 3 to 4 mm long) flowers that I have been able to peek into, and they are quite brittle and I can't quite count the parts. There is a perianth, composed of  both ovate (outer) and oblanceolate (inner) segments.  Stamens are 3 or more, the filaments neither connate nor inserted on the petals.  Anthers are long-sagittate and basifixed, filaments varying in length.  There are glands or staminodes as well--some of the ones nearest the periphery of the flower are glandular toothed and quite frilly; those nearest the stamens seemingly attached to them, shorter, and not so frilly.  Ovary superior, ellipsoid, slightly elevated above the attachment point of the perianth and stamens; style 1, terminal, slightly flattened in the middle.  Developing fruit with pedicel spreading to slightly deflexed (or this perhaps a remnant of pressing).
