Genetic Variation Patterns of “Algarrobos”
from the “Great American Chaco”
(Prosopis alba, P. nigra, P. hassleri, P.
fiebrigii, P. ruscifolia, P. chilensis, and P.
flexuosa)

The genus Prosopis comprises approximately 44 species of trees and shrubs distributed in arid, semi-arid, and subhumid zones of America, Africa, and West Asia
(Burkart 1976). Although some species are native to North Africa, Asia, and North
America, the “Great American Chaco” constitutes its main center of diversity. The
greatest number of endemism and species is distributed in virtually all environments
of this large phytogeographic region (Burkart 1976; Ferreyra et al. 2010). Burkart
(1976) defined the taxonomic delimitation of the genus and proposed an intragenus
classification in five sections (Prosopis, Anonichium, Strombocarpa, Monilicarpa,
and Algarobia) based on floral and vegetative characters. Prosopis alba, P. nigra,
