Studies on Homalomeneae (Araceae) of Borneo VI: Homalomena giamensis, a New Species from Sarawak, Malaysian Borneo, with Observations on its Pollination

A new species, Homalomena giamensis L.S.Tung, S.Y.Wong & P.C.Boyce, is described and illustrated from karst limestone formations at Kampung Giam, Kuching Division, SW Sarawak, to where it is locally endemic. As part of an ongoing project to investigate triggers and barriers in speciation process...
