摘要

Skimmia (Rutaceae) from Mt. Shiwandashan, Guangxi Autonomous Region, China was studied. On the basis of field and herbarium works, all the Skimmia found there were determined as S. arborescens Gamble subsp. nitida N. P. Taylor & Airy Shaw, a dioecioustree with black fruits. Its chromosome number was 2n = 30, the first report for this subspecies. The karyotype was similar to that of S. japonica subsp. japonica var. japonica in having large metacentric pairs, no supemumeral chromosomes and sometimes having satellites on the middle chromosome pairs. Its arm ratio was more symmetric than other Skimmia species studied until now.
