TL;DR: In this paper, the chemical constituents of the leaves of Hoya meliflua were identified by NMR spectroscopy and the triterpenes and sterols obtained from Hoya were also identified from other Hoya species.
TL;DR: Hoya meliflua , H. treubiana and H. luzonica are typified and a recent neotypification of H. fraterna is considered invalid, the original type is reinstated and an epitype is designated.
Abstract: Hoya meliflua , H. treubiana and H. luzonica are typified. A recent neotypification of Hoya meliflua ssp. fraterna is considered invalid, the original type is reinstated and an epitype is designated. Upon examination of the type specimens, H. davaoensis, H. luzonica , H. meliflua ssp. fraterna and H. treubiana are considered conspecific with H. meliflua .
