摘 要 ：首次报道了假糙苏属两个种的染色体数目,分别为:刚毛假糙苏Paraphlomis hispida C.Y.Wu2n=2x=34;假糙苏P.javanica(Bl.)Prain 2n=2x=34,染色体基数为17。而糙苏属染色体基数为x=10和11,因此支持将假糙苏属作为独立的属。

Abstract:In this paper, chromosome numbers of two Paraphlomis species were reported for the first time.The chromosome numbers of the tested two species,Paraphlomis hispida and P.javanica,are the same,namely 2n=2x=34 and their basic chromosome number is x=17,which is different from x=10 or 11 for Phlomis.Therefore,our results indicate that Paraphlomis and Phlomis are different genera,respectively.
