Margelliantha lebelii, a new species of Margelliantha from Nyungwe National Park, Rwanda

摘要

A new species of Margel/iantha from Nyungwe National Park in Rwanda is described. It differs from all other species of the genus by the very succulent leaves with distinct unequally bilobed apex, and the curved spur. Margelliantha lebelii grows as anepiphyte on the drier Eastern slope of the Congo-Nile watershed. A key to all species of Margelliantha is presented.
