Taxonomic novelties in New Guinea Uvarieae (Annonaceae): Revision of <i>Pyramidanthe</i> and new genus records of <i>Desmos</i> and <i>Fissistigma</i>.

ABSTRACT: The diversity of climbing Annonaceae in New Guinea, the world's largest tropical island, remains poorly known. Here, we provide a regional taxonomic account for three genera of the Uvarieae tribe, two of which represent new genus records for the island. First, we revise the genus Pyramidanthe (formerly Mitrella), recognizing a total of seven species. Four are described as new, P. montana, P. nervosa, P. oblongifolia, and P. parvifolia, whereas another, P. silvatica, is synonymized under P. schlechteri. Two additional Uvarieae genera, Desmos and Fissistigma, are recorded in New Guinea for the first time. Desmos is reported with the description of a new species, D. insolens, based on a single fruiting collect
