英文摘要: Karyotypes of thirteen species (including 3 subspecies, 2 varieties) of Pedicularis L. (Orobanchaceae) from the Hengduan Mountains Region, NW Yunnan, China were investigated. Twelve species of them were reported for the first time. The species examined all had one or other of two basic chromosome numbers: 2n=14 and 2n=16. All species investigated are diploid and share the same type of choromocenters in prophase nuclei, but differed in their interphase nuclei. The species with 2n=14 have the simple chromocenter type of interphase nuclei, while those with 2n=16 have the complex chromocenter type of interphase nuclei. These results confirm former reports, which have shown that 2n=16 is by far the most common number in this genus. Based on the karyomorphological evidence as well as morphological characters, relationships between the species studied are discussed.
