Studies on Homalomeneae (Araceae) of Borneo VII: Homalomena debilicrista, a new species from Malaysian Borneo, and observations of its pollination mechanics

Homalomena debilicrista Y.C.Hoe is described and illustrated as a species new to science from the Matang massif sandstone formation, Kuching Division, NW Sarawak, Malaysian Borneo. It represents the sixth species of the informal Hanneae Complex, a morphotaxon apparently endemic to Borneo and compose...
