英文摘要	Primula interjacens Chen (Primulaceae) is a rare and narrow endemic species of centralsouth of Yunnan Province in China. This species consists of two varieties: P. interjacens var. interjacens known with only one population, and P interjacens var. epilosa with two populations. Inter-simple sequence repeat (ISSR) marker was used to detect the genetic diversity of the three extant populations. We expected a low genetic diversity level, but our results revealed a high level of intraspecific genetic diversity (at population level: P = 59.75%, H-E = 0.236 8, and Hpop 0.345 9; at species level: P =75.47%, H-T= 0.320 5, and Hsp = 0.461 8), probably resulting from floral heteromorphism and preferring outcrossing. A moderate level of genetic differentiation among populations was detected based on Nei's genetic diversity analysis (26.13%) and Shannon's diversity index (25.09%). Although P interjacens var. interjacens and P interjacens var. epilosa were morphologically distinct, UPGMA cluster analysis showed that the two varieties had no distinct genetic differentiation and may be treated as a single taxon. Conservation measures are suggested, including in situ and ex situ strategies, based on the observed population genetic information.
