Gravesia gautieri (Melastomataceae: Sonerileae), a new species from northern Madagascar

This dataset contains the digitized treatments in Plazi based on the original journal article Almeda, Frank, Pacifico, Ricardo (2025): Gravesia gautieri (Melastomataceae: Sonerileae), a new species from northern Madagascar. Phytotaxa 721 (3): 288-294, DOI: 10.11646/phytotaxa.721.3.8, URL: https://doi.org/10.11646/phytotaxa.721.3.8AbstractGravesia gautieri, a new species from northern Madagascar, is described, illustrated, mapped, and compared with presumed relatives based on morphological characters. It is readily diagnosed by its sparingly branched suffrutescent habit, 3-nerved leaf blades that are coarsely and remotely serrate at least distally with a sparse cover of minute brown granular hairs and ± appressed smooth hairs abaxially, long-pedunculate umbellate inflorescences, ± terete and ecostate hypanthia, obsolete calyx lobes with callose-thickened teeth borne on and barely exceeding the calyx tube in length, and dorso-basal subulate staminal appendages that are deflexed to variously coiled.
