Four new species of Breynia (Phyllanthaceae / Euphorbiaceae sensu lato) and one new combination from Thailand and Malaysia
Four new species in Breynia are described. These species belong in fact to the genus Sauropus, but this publication anticipates the formal transfer of all Sauropus species to Breynia. Breynia lithophila sp. nov., B. carnosa sp. nov., and B. obscura sp. nov. are local endemic species hanging down from limestone rocks. Breynia repens sp. nov. is found on the ground in rainforest and displays a variegated leaf. Three of the species are new for Thailand, and one is new for the Malay Peninsula. The new Malay species was formerly tentatively identifi ed as ‘Sauropus calcareus’: this species is described again here and the new combination Breynia calcarea is made.
