Abstract:Based on the list of wild plant species of national importance issued in 1999 （first part） and the recorded data, there are 9 taxa of national protection grade I distributed in Guangdong Province, viz. Cacys taiwaniana, Cycas fairylakea, Ginkgo biloba, Glyptostrobus pensilis, Mussaenda anomala, Primulina tabacum, Sinia rhodoleuca Taxus wallichiana var. mairei and Bretschneidera sinensis. A survey of the 9 taxa was made during 1998 to 2001, with complementary investigation afterwards. According to IUCN red list 2001 categories and criteria, Cacys taiwaniana, Glyptostrobus pensilis and Mussaenda anomala are extinct in the wild （EW）. Ginkgo biloba is critically endangered （CR）. Bretschneidera sinensis, Sinia rhodoleuca, Primulina tabacum and Cycas fairylakea are endangered （EN）. Taxus wallichiana vat. mairei is nearly threatened （NT）. Conservation strategies of the 9 taxa are suggested.
