“…Standley (1922), in the treatment of the Trees and shrubs of Mexico, did not include Senegalia. The genus was recognized by Britton & Rose (1928) among others; later Seigler et al (2006b), transferred some of the species of Acacia subgenus Aculeiferum Vassal to Senegalia, but Rico-Arce (2007) included all in Acacia.…”

“…The name remained in Senegalia for almost 80 years. Then, Seigler et al (2006b) included it as a synonym of S. roemeriana (Scheele) Britton & Rose (1928), but Rico-Arce (2007) considered that S. saltilloensis is a different species from S. roemeriana and transferred it to Acacia, publishing it as a new nomenclatural combination. Tropicos.org from the Missouri Botanical Garden (TROPICOS, 2016) and The Plant List from the Royal Botanical Gardens at Kew (The Plant List, 2016) follow this nomenclature and consider it as a name in current use.…”

“…The plants named as Senegalia are distinguished by having prickles and no stipular spines, petioles with glands and absence of phyllodes, pedicellate ovaries with glands at the base, and porate pollen grains (Seigler et al, (2006b) Senegalia saltilloensis was described by Britton & Rose (1928) selecting as the type E. Palmer 169, from near Saltillo, Coahuila. A Latin diagnosis is not included, neither a "holotype" was designated, and four to five duplicates are currently annotated as isotypes at A, BM, MO, NY, and US.…”

“…While many of the species names in Senegalia given by Britton & Rose were reduced to synonymy (Seigler et al, 2006b), S. saltilloensis was included under S. roemeriana. Besides the type material, no other herbarium specimen was found with the name Senegalia saltilloensis.…”

“…According to this classification, Acacia sensu stricto is restricted to the "Australian group of species" (Maslin, 2008) and some others in the Pacific Islands (Pedley, 1978). In America, Senegalia includes most of the species of Acacia subgenus Aculeiferum and some other new nomenclatural combinations for the genus (Seigler et al, 2006b;Glass and Seigler, 2006). Some other species of the subgenus are included in the new genus Mariosousa (Seigler et al, 2006a).…”

AbstrAct:Background and Aims: The mimosoid genera Senegalia and Acacia are closely related. Acacia sensu lato is a polyphyletic group that can be split in the following genera: Vachellia, Senegalia, Acaciella and Mariosousa, remaining as Acacia (sensu stricto) only the "Australian species" and some others from the Pacific Islands. The American species of Senegalia and the new genus Mariosousa include the elements of Acacia subgenus Aculeiferum. We agree with this criterion. Senegalia saltilloensis was described by Britton & Rose in 1928, followed by synonymization with S. roemeriana, and was later re-evaluated as a valid species, creating a new nomenclatural combination in the genus Acacia. The aim of this study was to know the identity of the poorly known plants named as Senegalia saltilloensis. Methods: A morphometric analysis was carried out. A total of 70 specimens were examined and 21 characters were evaluated to find the similarity between Senegalia saltilloensis and Senegalia roemeriana. Key results:The results show no significant morphological difference between the two entities. Conclusions:The name Senegalia saltilloensis should be maintained as synonym of the well-known name of Senegalia roemeriana.

Evidence of the effects of agriculture on natural systems is widespread, but potential evolutionary responses in nontarget species are largely uncharacterized. To explore whether exposure to agrochemicals may influence selective pressures and phenotypic expression in nonagricultural plant populations, we characterized the expression of putative antiherbivore defense phenotypes in three nonagricultural species found upstream and downstream of irrigated rice fields in Guanacaste Province, Costa Rica. We found that plants downstream of chemically intensive agriculture showed shifts toward reduced expression of putative antiherbivore defenses relative to upstream counterparts. In two of three tested species, leaf extracts from downstream plants were more palatable to a generalist consumer, suggesting a possible reduction of chemical defenses. In one species with multiple modes of putative defenses, we observed parallel reductions of three metrics of putative biotic and physical defenses. These reductions were concurrent with reduced herbivore damage on downstream plants. Together, these results suggest that agriculture has the potential to alter intraspecific phenotypic expression, ecological interactions, and natural selection in nontarget plant populations.
