Genetic Diversity Of The Narrow Endemic Allium Aaseae (Alliaceae), James F. Smith, T. Vuong Pham

Low levels of genetic variability are common for a number of geographically restricted plants: these data are consistent with theoretical expectations that small populations should be genetically depauperate. However, in some species, high levels of variability have been found in rare species. Allium aaseae is a rare, narrow endemic in the foothills of the Boise Front of southwestern Idaho. Genetic variation in the rare endemic A. aaseae, and nearby populations of the more common species, A. simillimum, was examined with randomly amplified polymorphic DNA (RAPD) data. Eight populations of A. aaseae and six populations of A. simillimum (three near the …
