Two new species from the mountains of southern Malawi and northern Mozambique

Abstract

SummaryTwo new species are described from the proposed Mulanje-Namuli-Ribáuè Centre of Endemism. Isoglossa perdita I.Darbysh. (Acanthaceae) is apparently restricted to the submontane forests of southeastern Mt Mulanje in Malawi, and is assessed as Critically Endangered. Agelanthus patelii Polhill & Timberlake (Loranthaceae) is recorded from the montane forests of Mt Mulanje and from Mt Namuli in Mozambique, and the earlier assessment of this species as Endangered is confirmed. The habitat preferences and taxonomic affinities of these species are discussed. This work contributes to the ongoing assessment of the biodiversity and endemism of this montane region, and to the identification of Important Plant Areas in Mozambique.
