Abstract: The present paper reorts karyotypes in 11 species and 1 varietie of Glycgrrhiiza L. in China. It is found that all of the are diplode, with 2n=2x=16; their complemets are made of median and submedian chromosomes and them only G. glabra var. laxifoliolata and G. korshiskyi has apair of subterminal. The karvotype formulae are as follows:G. pallidiflora 2n=2x=16=8m+4m+sm; G. aspera 2n=2x=16=2M+8m+6sm; G. shihezinsis 2n=2x=16=2M+6m+8sm; G. eurycarpa 2n=2x=16=2M+6m+8sm; G. macraphylla 2n=2x=16=14m+2sm; G. inflata 2n=2x=16=10m+6sm; G. uralensis 2n=2x=16=6m+10sm; G. glabra 2n=2x=16=6m+10sm; G. prostraca 2n=2x=16=4m+12sm; G.glabra var. laxifoliolata 2n=2x=16=10m+4sm+2st; G. korshinskyi 2n=2x=16=4m+10sm+2st; G. yunnanens.s 2n=2x=16=4m+8sm+4st.
