The taxonomy of Hoya micrantha and Hoya revoluta (Apocynaceae, Asclepiadoideae)

Abstract

Hoya revoluta, Hoya micrantha, and their synonyms are typified and revised. Hoya plicata, currently a synonym of H. micrantha, is reinstated and applied to a taxon from montane forests of Peninsular Malaysia; Hoya rundumensis is proposed to replace Hoya plicata subsp. rundumensis, a Bornean endemic; Hoya inconspicua is separated once again from Hoya revoluta; a new species, Hoya beccarii, is recognised and described. © 2013 Dipartimento di Biologia, Università di Firenze.
