Marsdenia burmanica Wen B.Xu & J.Y.Shen (Apocynaceae), a new species from Hongga Mountain, Putao County, Kachin State, Myanmar, is described and illustrated. It is similar to M. hainanensis, M. sinensis, and M. tenii, but differs from them by campanulate flowers, fusiform gynostegium exserted from the corolla tube, 2-cleft stigma head, purple corolla and a corona of 2 oval protrusions at the base of the corona. Photographs, line drawing, distribution, comparison with related species, and a conservation assessment are provided for this rarely observed species.
