Abstract
In the present paper, we describe Hoya biruensis, a new species from Borneo, Indonesia, West Kalimantan. It is characterised by a shrubby epiphytic pendulous habit, linear leaves, exceptionally long green peduncles produced at almost every node, and single, night-blooming flowers. We compare it to two morphologically similar species, H. spartioides and H. retrorsa, which are also endemic to Borneo.
Keywords: epiphyte, Hoya retrorsa, Hoya spartioides Indonesia, West Kalimantan
