Cayzer, LindyChandler, G.T.2021-11-230374-7859http://hdl.handle.net/1885/251930The poorly understood ‘rusty-leaved’ pittosporum, Pittosporum ferrugineum W.T.Aiton has been comprehensively revised as part of the ongoing revision of the family Pittosporaceae across its range. Aiton’s Pittosporum ferrugineum s.s. has been found to be a different species to the species currently known as P. ferrugineum in the Malay Peninsula, Borneo and the Andaman Islands (India). Hence the common coastal species in these areas needs a new name and is presented here as Pittosporum ridleyi L.Cayzer & G.Chandler, a new name for an old species.application/pdfen-AU© 2018 Gardens' Bulletin SingaporeApialesPittosporum ferrgineumThailandSingapore201810.26492/gbs70(2).2018-092020-11-23
