Abstract

Wahlert, G.A. (2016). Novelties from the Northern Mountains Complex of Madagascar IV : A new Rinorea Aubl. (Violaceae) of restricted range from the Galoko and Kalabinono massifs. Candollea 71: 205–210. In English, English and French abstracts.

Rinorea callmanderi Wahlert (Violaceae), a new species from northwestern Madagascar, is described and illustrated. This new species was discovered during an intensive floristic inventory in the botanically unexplored Kalabinono and Galoko massifs. Based on morphological and molecular evidence, the new species is placed in Rinorea subsection Verticillatae Engl., the most species-rich group of Rinorea Aubl. in Madagascar. Rinorea callmanderi is morphologically most similar to Rinorea mutica (Tul.) Baill. by its opposite-leaved phyllotaxy and condensed, subsessile cymose inflorescence, but differs by the shape and size of the leaf, the pattern of pubescence on the inner surface of the petal, and the presence of dorsal and ventral anther connective scales. The new species is described and provided with line drawings, a distribution map, a discussion on its morphology, and a preliminary conservation assessment using the IUCN Red List Categories and Criteria.
