Abstract

Two new endemic species of Rhododendron of subgenus Vireya from Sulawesi are described, viz. R. ardii Hutabarat, Mambrasar & Mustaqim, and R. tjiasmantoi Mustaqim, Mambrasar & Hutabarat. Detailed morphological descriptions accompanied by a map of geographic distributions, plant illustrations, and discussions on habitat, ecology, and preliminary conservation status are presented.
