Abstract: There were 1266 species and infraspecies of wild plants belonging to 168 families, 605 genera in Qingyun mountain nature reserve, Guangdong Province, China. The wild medicinal plants included 586 species belonging to 140 families, 385 genera. The 8 families including species more than 15 were as follows: Compositae, Rubiaceae, Gramineae, Labiatae, Orchidaceae, Papilionaceae, Euphorbiaceae, and Scrophulariaceae. According to their effectiveness, they were classified blood-activating and stasis-elirninating (including 107 species), heat-clearing and detoxifying (90 species), cough relieving and lung clearing (60 species), enteritis treating (58 species), traumatic hemorrhage (56 species), snake bite treating (56 species), and detumescence and pain relieving (30 species). According to their medicinal parts, they were classified medicinal plants of whole plants (including 304 species), roots and rhizomes (185 species), leaves (131 species), stems (49 species), cortexes (47 species), fruits (42 species), flowers (14 species) and others (20 species). The result showed that the correlation analyses of life forms, habitats and altitudes of these medical plants were significantly different.
