The genetic structure of a columnar cactus with a disjunct distribution: Stenocereus gummosus in the Sonoran desert.

Heredity - 1 Jun 2003

Clark-Tapia R, Molina-Freaner F

Abstract excerpt

Stenocereus gummosus is a columnar cactus endemic to the Sonoran desert that exhibits a disjunct distribution: it is widely distributed in Baja California and restricted to a small coastal area in mainland Sonora. In this paper, we examine the genetic structure and the mating system of this species in order to explore the origin of the disjunction and describe aspects of the pollination biology. Flowers are...
