 Eleutharrhena macrocarpa is a grade protected wild plant,also known as one of the tiny population. Through consulting relevant literature and records, access specimen investigation and field survey, A survey on geographical distribution、community and population status of it was conducted. The results show that: (1) there are a counter of 19 distribution points of Emacrocarpa, since 1910, the first time it was found in China; (2) E. macrocarpa is discontinuously distributed in the tropical rainforest regions of the south, southeast and southwest of Yunnan and Napo in Guangxi. Due to its habitat were severely damaged, 9 of the original record distribution points were disappeared, the number of existing distribution points which was reliable reduce to 10; (3) According to the reliable survey, the number of it just is about 40 strains, and we did not see its seedlings. it show that its natural regeneration is difficulty. Based on the results of the survey, discuss its endangered reasons, and provides the theoretical basis to protect them effectively.
