Abstract
The genus Furtadoa M. Hotta (Araceae) is reviewed, with its morphological characteristics compared to those of Homalomena Schott, and its molecular phylogenetic position analyzed in relation to other Homalomena species. A comparative assessment of molecular data supports the reclassification of Furtadoa within Homalomena, resulting in the establishment of two new combinations. Two species names are changed: H. indrae for F. indrae and H. sumatrensis for F. sumatrensis. In this paper, we also describe a new species of ‘Furtadoa-like’ Homalomena from Riau, Sumatra, H. chikmawatiae A.S.D.Irsyam & M.R.Hariri. This new species is readily identified by its peltate leaves and large sterile appendix at the spadix.

Homalomena chikmawatiae A.S.D.Irsyam & M.R.Hariri, sp. nov.
Diagnosis: Homalomena chikmawatiae is readily distinguishable from other Homalomena species with ‘Furtadoa-type’ spadices by its clearly peltate leaves and the conspicuous sterile appendix at the upper 2/5 of the spadix.
