Variability in mating strategies in a widespread cactus in the Chihuahuan Desert
Opuntia is the most diverse and widespread genus in the Cactaceae; several species have broad distribution ranges and have successfully adapted to distinct habitats. One explanation for their success is the diversity of their reproductive systems. Opuntia macrocentra is one of the most common widespread species in North American deserts.

Mating system of Pachycereus pringlei: an autotetraploid cactus [PDF]
The mating system of the Mexican subdioecious columnar cactus, Pachycereus pringlei (Cardon), was examined by allozyme analysis. Tetrasomic patterns of inheritance were found for all polymorphic loci, indicating that the species is an autotetraploid.

Asynchronous flowering patterns in saguaro cacti (Carnegiea gigantea)
Abstract The saguaro cactus (Carnegiea gigantea [Engelm.] Britton & Rose) is a keystone species endemic to the Sonoran Desert of northern Mexico and the southwestern United States. The saguaro produces large white flowers near its stem apex (crown) during April–June, which bloom at night and close the following day.

Human food use increases plant geographical ranges in the Sonoran Desert
Abstract Aim Climate is usually regarded as the main determinant of plant species distributions. However, past human use of species for food might also have influenced distributions. We hypothesized that human‐mediated dispersal has resulted in food plants occupying more of their potential geographical range.
