Re-evaluating monotypic Eleutherostylis from New Guinea and the Moluccas and its inclusion in Grewia (Malvaceae, Grewioideae)

Morphological and molecular phylogenetic evidence indicate that Burret (Malvaceae, Grewioideae), a monotypic genus described from New Guinea, is best considered a synonym of L., a species-rich genus widespread across the Paleotropics and found in Africa, Arabia, Asia, Australia and the western Pacific. A new combination, based on Burret, (Burret) Dorr, , is proposed. Original material of the basionym could not be located and a neotype is designated. A lectotype is designated for Kosterm., a synonym of .
