Abstract:

 Seven species of Glycyrrhiza in China are karyologically analyzed in this pa-
per. The results are as follows: G. uralensis Fisch. 2n=16=6m+10sm;    G. eurycarpa P.C.
Li 2n=16=8m+6sm+2st; G. glabra L. 2n=16=14m+2sm; G. inflata Bat. 2n=16=6m+10
sm; G. aspera Pall. 2n=16=12m+4sm; G. yunnanensis Cheng f. et L. K. Tai ex P. C. Li 2n
=16=12m+4sm; G. pallidiflora  Maxim. 2n=16=12m+4sm.
      From this work and the previous reports, it is presumed that the basic chromosome num-
ber of Glycyrrhiza is x=8. Based on the characters of karyotype so far realed, the authors
consider that the genus Glycyrrhiza is a relatively primitive group in Leguminosae and  G.
pallidiflora is the most primitive one among the species dealt with in this paper, and G. eurycar-
pa is the most advanced one.
