Abstract
The chromosome number and karyotype of Fosbergia shweliensis(Anth.) Tirveng. Sastre are reported firstly.The results show that the chromosome of Fosbergia shweliensis is diploid and small,its length ranges from 1.25 μm to 2.25 μm,the karyogram fits well to the formula of 2n=2x=22=10m+2sm,and the karyotypc belongs to the type of 2A.
