Ecology & Habitat — Unknown.

Distribution — Indonesia, West Papua Province, Manokwari, middle Legari R., Janowski 68 (L).

Note — Only the single collection is known. The combination of petiolate, lanceolate leaves and shortly pedunculate inflorescences fits no other species, and Valeton prepared a manuscript name ‘falcatum’. The paucity of the available material makes us cautious to establish a new species.
