TL;DR: A revision of the genus Lasiodiscus Hook is presented and the delimitation of this genus from Colubrina L. f.
Abstract: A revision of the genus Lasiodiscus Hook. f. is presented and the delimitation of this genus from Colubrina L. C. Rich. ex Brongn. is discussed. Twelve species are recognised. Two new species, L. lebrunii E. Figueiredo and L. palustris E. Figueiredo, are described and the new combination L. pervillei ssp. ferrugineus (Verdc.) E. Figueiredo is made. L. articulatus Capuron is transferred to Colubrina (C. articulata). One neotype and four lectotypes are selected.
Abstract: A cladistic analysis of Lasiodiscus Hook. f. and Colubrina Rich. ex Brongn. was undertaken, using characters from gross morphology and with 10 of the 13 species of Lasiodiscus and 19 of the 32 species of Colubrina as terminal taxa. The cladograms indicate that, with the exclusion of L. articulatus Capuron several synapomorphies characterize Lasiodiscus. The inclusion of this species in the genus obscured the boundary between Lasiodiscus and Colubrina. L. articulatus should be transferred to Colubrina.
