Contribution to a revision of Hoya (Apocynaceae: Asclepiadoideae) of Papuasia. Part II: eight new species, one new subspecies

Abstract

In the present paper we publish eight new species from New Guinea, H. domaensis, H. gauttierensis, H. liddleana, H. lucida, H. paradisea, H. pulleana, H. tarikuensis, and H. unirana, and one subspecies, H. krusenstierniana subsp. laticorolla. Five taxa were first diagnosed based on specimens at the Leiden herbarium, one species is only known from a collection at Edinburgh and Lae herbaria, while three are based on recently collected specimens. Hoya leucantha, originally described from a specimen in bud, has been identified among herbarium specimens and was also recently recollected. It is therefore fully described and illustrated for the first time.
