Amorphophallus minimus (Araceae), a new species from the montane forest of Nueva Ecija, Luzon island, Philippines

Amorphophallus minimus (Araceae) is herein described and illustrated as a new species from the montane forest of Nueva Ecija, Luzon island, Philippines. A. minimus has an overall resemblance to Amorphophallus palawanensis Bogner and Hett., however, it is easily distinguished by having a club-shaped and colliculate appendix that is contiguous with the male zone, oblate stamens (2 per flower), presence of leaf bulbils, and its overall small dimensions. Amorphophallus minimus is currently the only species in the Philippines found to inhabit a montane forest ecosystem.
