Abstract

Rigiolepis bungeputih Mustaqim & M.N.Tamayo, a close relative of blueberries (Vaccinium L.) and endemic to the tropical evergreen mossy rainforest of northern Gayo Plateau, Sumatra, Indonesia, is here described. It closely resembles R. gayoensis Mustaqim, M.N.Tamayo & P.W.Fritsch, but differs by having a glabrous stem, larger leaves, glabrous pedicels, white corollas, and larger stamens. Photographs, an illustration, and a detailed morphological description are included. Rigiolepis bungeputih represents the second endemic Rigiolepis Hook.f. species known from the island of Sumatra. This discovery raises the number of Rigiolepis species found in this island to four. A discussion on the ovary character of Rigiolepis in view of ongoing molecular studies is presented.
