Abstract

Abstract:

This study reports the distribution of a newly recorded species Polygonatum sinopubescens (Polygonatum,Liliaceae) in the National Nature Reserve of Gaowangjie,Guzhang county,Hunan,China.The karyotype of the chromosomes of Polygonatumsinopubescens is also reported.The chromosome numbers is 2n=18 with the karyotype formula being 2n=2x=12m (2sat)+6sm (2sat) and the type is 3B.The discovery of occurrence locality provides more diverse samples for further classification and phylogenetic analysis,and also offers the basic information for protection and rational development of germplasm resources.

Key words: Polygonatum sinopubescens, Polygonatum, karyotype, Hunan Province
