Wahlert, G. A., P. B. Phillipson, L. Nusbaumer & L. Gautier (2012). Cyphostemma darainense Wahlert & Phillipson (Vitaceae), a new species from northeastern Madagascar. Candollea 67: 277–283. In English, English and French abstracts.

Cyphostemma darainense Wahlert & Phillipson (Vitaceae), a new species from northeastern Madagascar, is described and illustrated. Recent floristic inventories in the Loky-Manambato region of northeastern Madagascar have highlighted the area as an important area of local endemism for plants. The new species was identified after survey of the collections for this genus in the Geneva herbarium and latter confirmed during the preparation of the treatment of Vitaceae for the “Catalogue of the Vascular Plants of Madagascar”. Observations about its ecology are also provided, its potential range is modeled using the statistical package “BIOMOD”, and its preliminary IUCN conservation status is given.
