Description
|
Shrub or sprawling vine; stems glabrescent, drying almost black, twigs ferrugineous with mostly short-stalked, long-radiate, stellate and dendritic hairs. Leaves coriaceous, to 7 cm long, broadly ovate or elliptic, apically obtuse or short acuminate, basally rounded or obtuse, the margins strongly revolute, glabrescent above with obscure venation and drying black, the veins prominently elevated beneath, tomentose to glabrescent, the lamina glabrous drying yellow-green, veins ca. 2 on each side; petioles short, ca. 10 mm long; minor leaves wanting or equalling the major leaves, the nodes thus appearing opposite-leaved. In- florescence solitary or a few-flowered fascicle; pedicels persistently ferrugineous, 10 mm long, elongating to 20 mm and thickening in fruit. Flowers with the calyx cup 4 mm deep, pubescent, with 10 well-spaced teeth 5 mm long; corolla with thickened pubescent interplicae, mature flowers not seen. Fruit shiny, bright orange or red, ca. 14 mm across; the calyx scarcely enlarged; seeds large, com- pressed-discoid, ca. 5 mm long with a thickened margin.

Note
|
Superficially, the texture of the leaves and young flowers is strongly sug- gestive of L. acidochondra, which grows in the same region. However, the glabrous lamina and usually glabrescent veins on the leaf undersides and the non-accrescent calyx are manifest distinctions.
