Genetic variation in Aciphylla glaucescens (Apiaceae)

Population structure, diversity and gene flow in four populations of Aciphylla glaucescens were studied using allozymes. Six of the seven putative loci were polymorphic in at least one population. Within populations the mean percentage of polymorphic loci was 68%. Gene diversity for Aciphylla glaucescens (H-e = 0.258) was greater at the species level compared with other outcrossing, wind pollinated plant species (H-e = 0.162). The mean diversity among populations of A.
