摘要	Investigated in the present paper is the karyomorphology of 7 species in 3 sections of Podocalpus s.1. from Yunnan province of China. All species commonly showed the mitotic prophase chromosomes of the same interstitial type, but different resting nuclei type. The resting nuclei were found the gradient type for Sect. Dacrycarpus, the simple chromocenter type for Sect. Nageia and the complex chromocenter type for Sect. Podocarpus respectively. The karyotype formulae were 2n=20=16M+4SM for Podocarpus imbricatus, 2n=26=9M+17SM for P. nagi, 2n=26=17M+9SM for P. wallichiana, 2n=26=13M+13SM for P. fleuryi, 2n=38=19M+3SM+2ST+8T for P. macrophyllus var, angustifolius, 2n=38=18M+10SM+2SM+8T for P. forestii, and 2n=38=20M+10SM+8T for P. neriifolius respectively. The karmorphology of 3 sections in Podocarpus, especially the resting nuclei and basic chromosome number, together with the other data, justified their generic status in the family.
