This is a species that we collected in 1978 in Rancho Grande, the beautiful national park in Aragua state on the northern coast, with jungle covered mountains. I can still recall finding this plant growing over a swift stream right above a waterfall and puzzling about how we could get a piece of it without risking our lives. Anyway we did and subsequently donated the plant to the Marie Selby Botanical Gardens (SEL78-0673). The forest was fairly open but had a tall canopy so was quite deeply shaded and cool, at 3,800 feet of altitude. An odd looking species with sort of knobby stems, almost always with small, greenish-white flowers but never very many, and white fruits too, in small numbers. Grows as do most other Rhip species, with little effort.
Note: This plant is on C.I.T.E.S. and can not be exported.
