The Convolvulaceae of Timor with special reference to East Timor

Abstract

A taxonomic review of the Convolvulaceae in Timor is presented. A total of 61 taxa are listed, comprising 53 species from 15 genera. The most diverse genus by far is Ipomoea with 25 reported species, followed by Merremia with seven species. Of the seven species initially thought to be endemic, only six are endemic to the island. Two new records are presented (Cuscuta campestris and Merremia quinata) and a new species, Argyreia paivae, is described and illustrated. Keys to genera and species are included, as well as distribution maps. The conservation of East-Timorese Convolvulaceae is analysed and it is shown that they are inadequately represented in the established natural reserves’ network.
