Description

Shrub, subshrub or treelet, 1-4 m tall, somewhat nodose, glabrous. Petiole 0.5 cm long, glabrous, vaginate near or at base; blade glossy, coriaceous, not scabrous, not conspicuously glandular-dotted, elliptic-oblong, 13-30 x 5-8(-10) cm, apex acuminate, base equal or almost equally attached to petiole, acute, glabrous; pinnately veined, secondary veins 6-8 per side, flat to impressed above, prominent below, anastomosing well within margin, originating from throughout primary vein, tertiary veins widely reticulate. Inflorescence erect; peduncle 1 cm long, glabrous; spike 10-12 cm long, green, not apiculate; rachis hirsute; floral bracts cucullate, pilose on inner side. Fruits ovoid to tetragonous, separate, somewhat ridged or winged (at least when dried), glabrous may be somewhat papillose, stigmas 4, sessile.

Notes

I agree with Trelease and Yuncker (1950: 410) that Piper warakabacoura and P. bartlingianum are conspecific. The differences used to separate the two, for instance by De Candolle, are on leaf size and shape and a few hairs on the fruits. With the large amount of collections studied, it can be concluded that the variation is such that it is not possible to maintain two species.

Uses

According to Miquel, Artanthe warakabacoura — meaning knee of the Warakaba bird — was used in Guyana and Suriname as one of the constituents of the Ourali poison.
