Venezuela and Colombia. The single species in this section is an infrequent occurrence in wet, shady banks and along streams in the Cordillera Oriental of the Northern Andes from southern Merida in Venezuela to Huila in Colombia, and then on the eastern edge of the Nudo de Pasto in Putumayo at elevations from 1,800 to 3.050 meters (Berry 1982).

The breeding system is hermaphroditic.

Habit—Erect to scandent, mostly glabrous subshrubs 0.5 to 2 m tall. Branchlets subterete, 2 to 4 mm thick, verrucose, green to dull purple; older stems terete, with light gray tan, finely fissured bark.

Leaves—Opposite, firmly membranous, broadly elliptic to obovate, acute to attenuate at the base, acute to acuminate at the apex, 5 to 16 cm long, 2 to 8 cm wide, dark matte green above, pale or flushed purple below, often with strigose hairs along the veins; midvein prominent below, secondary veins ten to twenty on either side of the midvein, subparallel and anastomosing 1 to 3 mm before the margin to form a distinct submarginal vein; margin glandular-serrulate.
