Abstract
Maesaflabellifera (Primulaceae-Maesoideae) from southeast Yunnan, China, is described and illustrated here. This new species belongs to the informal long corolla-tube species group and is morphologically similar to M.permollis and M.kurzii, but can be distinguished by lacking hairs, membranaceous leaves and long panicles with 7-16 branches. According to the IUCN criteria, M.flabellifera is assessed as "Least Concern".
