| 摘 要： | In this paper, Psammosilene tunicoides, an endemic species to China, was cytologically studied for the first time. The morphology of the nuclei at resting stage was categorized to be simple chromocentre type. The morphology of mitofic-pmphase chromosomes was categorized to be the interstitial type.28 chromosomes were observed at the mitotic metaphase, and 14 bivalent chromosomes were observed at diakinesis. So, the basic chromosome number was confirmed to be x = 14. Psomzr~silene tunicoides is different from Silene rubicunda in the basic chromosome number and the morphology of the nuclei at resting stage and mitotic-prophase chromosomes, because Sgene rub/cund has the basic chromosome number of x= 10 and 12, and its nuclei at resting stage and mitotic-prophase chromosomes is sparsely diffuse type and continuous type respectivrly.
