Abstract： Survey on plant resources plays a basic role in studying plant systematics and floristic evolutionary history and affinities, which is one of the important tasks of plant research in China. Although China has a rich accumulation in plant resources investigation with Flora of China and local flora records, data on plant resources in some remote areas are still lacking. Actinodaphne lecomtei Allen, Cinnamomum ilicioides A. Chev. and Carya kweichowensis Kuang A. M. Lu ex Chang et Lu are reported with new distribution records by morphological comparison in southern Yunnan, China, respectively. A. lecomtei was previously recorded to be found in Sichuan, Guizhou, Guangdong (Ruyuan) and Guangxi, China, C. ilicioides to be endemic to Guangdong, Hainan, Guangxi, China, and northern Vietnam, C. kweichowensis to be distributedinAnlong,Wangmo,Cenheng,Xingyi ofGuizhouetc., China.The newdistributionrecordsofA.lecomtei andC. ilicioides complements theweak areas in China, and provide a datafor analyzing relationshipbetween original species with genera and the taxonomic study of Lauraceae in China. The new distribution record of C. kweichowensis provides a new case at the species level for confirming the connection between C. kweichowensis and Annamocarya sinensis, furthermore, providesgermplasmresourcesforthedevelopmentofC.cathayensisproductioninYunnan.
