Abstract
A new species, Begonia rheophytica (§ Platycentrum), is described from northern Myanmar; it was initially confused with B. rhoephila, which is confined to Peninsular Malaysia. Comparison with other species with a rheophytic leaf shape is made. This new addition brings the number of currently recognised Begonia species in Myanmar to 73. An updated checklist of Myanmar Begonia species is also included.
