Abstract
In the course of our intensive floristic inventories for the flora of Myanmar, a new species of the genus Sapria (Rafflesiaceae), Sapria myanmarensis Nob. Tanaka, Nagam, Tagane & M.M. Aung is described and photographed. In addition, S. himalayana Griff. f. albovinosa Bänziger & B. Hansen is newly recorded in the country. A key to the species of Sapria presently occurring in Myanmar is provided.

Sapria myanmarensis Nob. Tanaka, Nagam., Tagane & M.M. Aung, sp. nov.
Diagnosis: Similar to Sapria himalayana Griff., but it is distinguished from it by a combination of features including vermilion perigone lobes with white-colored warts distributed only basally, a shorter perigone tube (1.5–2 cm vs. 3–4 cm in S. himalayana), a flat central disk (not bowl- or pan-shaped), a greater diameter of the disk crest (4–4.5 cm in diam. vs. 3.5–3.9 cm in diam. in S. himalayana) and crateriform ramenta.
....
Distribution: Endemic to Myanmar. Thus far known only from northwestern part (Kachin State and Sagaing Region).
Etymology: The specific epithet is derived from the name of the country.
Vernacular name (Myanmar): Taung Kyar, meaning “mountain lotus flower”.
