CATE Araceae, 17 Dec 2011.

Petiole drying ± uniformly mid-brown, leaf lamina drying barely discolorous. Spadix slightly tapering-cylindrical; stigma punctiform, raised. Nusa Tenggara (Pulau Flores - endemic) One of a group of species that includes R. apiculata Engl. (New Guinea), R. hollrungii K. Krause (New Guinea), R. sabit P.C. Boyce and R . ustulata P.C. Boyce, distinguished by long petioles and chartaceous cataphylls. Species in this group can be distressingly similar in overall appearance and are mostly separated on characters such as inflorescence position, presence or absence of a spadix stipe and whether the top of stylar region is truncate or conical. The meagre number of botanical collections for each species exacerbates the problem of 'sameness'. Rhaphidophora floresensis may be distinguished by flowering on adherent side shoots, by the sessile spadix and the prominently raised stigma.
Nusa Tenggara (Pulau Flores). Endemic.
