| Abstract: | The cytotaxonomic study on the two species of Arthropteris from Guangxi,China has been reported in this paper. The chromosome numbers are reported for the first time. The putative reproductive manners were inferred from cytological characters and spore counting. The chromosome numbers were n=40,2n=80(2x)in A. pallisotii and in A. repens. The reproductive types in A. pallisotii and A. repens were sexual diploid. The systematic significance of chromosome numbers winthin the genus was discussed. |
