Amorphophallus natolii (Araceae), a new species from limestone on Palawan, Philippines.

Amorphophallus natolii is described and illustrated as a new species from limestone hills near El Nido, Palawan island, Philippines. It differs most distinctly from other species of Amorphophallus with a densely hairy appendix by its much smaller size and dominant reddish pinkish colours of the spathe. A preliminary molecular analysis shows it to be in a basal position to a clade containing a few other species with similar appendices, to which it is also morphologically compared. It is certainly one of the most remarkable new discoveries in a genus containing ca. 200 species.
