Abstract
Recent fieldwork in Monywa District, Sagaing Region, Myanmar resulted in the discovery of a species new to science, Typhonium edule, which is herein described and illustrated. It superficially resembles T. lineare but differs in having wider spathe diameter, spathe limb 3–4 times longer than the tube, downwardly curved sickled-shaped staminodes and strongly stipitate appendix. Detailed description, colour plates, distribution map, phenology and ecology of this new Typhonium species are provided below.
