''Lasianthus'' is a genus of flowering plants in the family Rubiaceae. They are tropical subshrubs, shrubs, or rarely, small trees. They inhabit the understory of primary forests. None of them are known to have any use. ''Lasianthus'' has about 180 species. The type species for the genus is ''Lasianthus cyanocarpus''. 〔''Lasianthus'' In: Index Nominum Genericorum. In: Regnum Vegetabile (see ''External links'' below).〕 In 2012, a revision of ''Lasianthus'' in Malesia described 131 species.〔Hua Zhu, Marco C. Roos, and Colin E. Ridsdale. 2012. "A taxonomic revision of the Malesian species of ''Lasianthus'' (Rubiaceae)". ''Blumea'' 57(1):1-102. 〕 Another 30 or so species grow elsewhere in tropical Asia.〔Debendra B. Deb and Mohan G. Gagnopadhyay. 1991. "Taxonomic study of the genus ''Lasianthus'' Jack (Rubiaceae) in India". ''Journal of Economic and Taxonomic Botany'' 15(2):265-308.〕 Most of these are described in Flora of China〔Hua Zhu and Charlotte M. Taylor. 2011. ''Lasianthus'', pages 185-198. In: Wu Zhengyi, Peter H. Raven, and Hong Deyuan (editors). 1994 onward. ''Flora of China'', vol. 19: Cucurbitaceae - Valerianaceae, with Annonaceae and Berberidaceae.

Clayton (editors). ''A Revised Handbook to the Flora of Ceylon'', vol. 12. ISBN 978-90-5410-270-0 (vol.12) (See ''External links'' below).〕 Fifteen species〔David J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008). Cambridge University Press: UK. ISBN 978-0-521-82071-4〕 or perhaps as many as 20 species〔Bernard Verdcourt. 1976. ''Lasianthus''. pages 134-145. In: Rubiaceae (part 1). In: Roger M. Polhill (editor). ''Flora of Tropical East Africa''. Agents for Oversea (sic) Governments and Administration. London, U.K. (See ''External links'' below).〕 are known from tropical Africa. Two species (''Lasianthus panamensis'' and ''Lasianthus lanceolatus''),〔Elmar Robbrecht. 1982. "The identity of the Panamanian genus ''Dressleriopsis'' (Rubiaceae)". ''Annals of the Missouri Botanical Garden'' 69(2):427-429.〕 or possibly three, are native to the neotropics.〔 ''Lasianthus strigosus'', from Queensland, is the only species known from Australia. The Australian ''Ixora baileyana'' had at one time been placed in ''Lasianthus'' as ''Lasianthus graciliflorus''.〔Laurie G. Adams, Diane M. Bridson, and Elmar Robbrecht. 1987. "The Identity of ''Lasianthus graciliflorus'' Bailey (Rubiaceae)". ''Kew Bulletin'' 42(1):209-214.〕 Dried specimens of ''Lasianthus'' often shed their flowers and fruit. For this reason, misidentification is common, even in herbaria. The name ''Lasianthus'' has been misapplied to ''Lisianthius'' (also spelled as "''Lisianthus''" or "''Lisyanthus''"〔Lena Struwe. undated. Gentian Research Network (website). (See ''External links'' below0.〕), a genus in Gentianaceae. ''Lasianthus alatus'' Aublet is a misspelling of ''Lisyanthus alatus'' Aublet, a species now placed in ''Chelonanthus''. == Species == ''Lasianthus'' contains the following species.
