“…The species of Algarobia with high variability were largely considered outcrosser, with self-incompatibility system (Solbrig and Bawa, 1975;Solbrig and Cantilo, 1975;Neff et al, 1977;Simpson, 1977;Simpson et al, 1977;Hunziker et al, 1986). Recent studies on the mating system of P. alba, P. nigra, P. flexuosa, P. glandulosa, P. velutina, P. ruscifolia, and P.chilensis (Bessega et al, 2000b) indicated that they are mostly outcrosser, although about 15% selfing can occur.…”

“…Previous works (Hunziker et al, 1986;Saidman et al, 1996) indicated that the sections Algarobia and Strombocarpa are highly differentiated. The speciation process in these groups as well as their adaptive strategies seem to be quite different.…”

“…Studies based on species of the series Pallidae, Ruscifoliae, and Chilenses indicated that natural hybrids frequently occur in zones of sympatry even between species belonging to different series (Hunziker et al, 1986). However, no interserial hybrids have been recorded involving species of the series Sericanthae.…”

In the present work, isoenzyme electrophoresis was used to analyze the variability and phenetic relationships among seven American species of genus Prosopis belonging to three different sections: P. argentina (Monilicarpa), P. glandulosa, P. velutina, P. flexuosa, P. ruscifolia, P. kuntzei (Algarobia), and P. reptans (Strombocarpa). The genetic variability in P. argentina, P. reptans, and P. kuntzei was significantly lower than in the rest of the species analyzed. The species belonging to different sections are highly differentiated, but the relationships retrieved among species belonging to the section Algarobia suggested that the series of this section are not natural groups. P. kuntzei is as differentiated from the remaining species of Algarobia as from P. reptans or P. argentina, suggesting that this species might be included in a different section. The series within section Algarobia are not supported by the clusters retrieved in the phenogram based on isoenzymatic data. The results suggest that the two North American species (P. velutina and P. glandulosa) would have originated in different founder events.

“…Isozyme and amino acid analysis also show that the genetic and morphological differences are high among species in section Strombocarpa compared to Algarobia (Carman et al 1974;Saidman et al 1996). Hence suggestions have been made to treat the two sections as subgenera (Hunziker et al 1986;Saidman et al 1996).…”

“…Kunth and P. juliflora (Sw.) DC., two truly tropical species of this genus (Pasiecznik et al 2001), belong to section Algarobia. The possibility of interspecific hybridization among species of this section has been reported by Naranjo et al (1984) and Hunziker et al (1986). The two species are similar in leaf morphology and tree form, and Pasiecznik et al (2001) assumed that naturally occurring hybridization in their overlapping native ranges led to the difficulty in differentiating the two species.…”
