Name

Senegalia riparia (Kunth) Britton & Rose ex Britton & Killip, Ann. New York Acad. Sci. 35:  144. 1936;

Synonymy and types

Acacia riparia Kunth., in Humb. Bonpl. & Kunth, Nov. gen. sp. 6:  276.  (218 in quarto edition).  1823.  - TYPE:  PERU.  ad confluentem fluminis Amazonum et Chamayae (Provincia Jaen de Bracamores), alt. 225 hex., Humboldt & Bonpland s.n. (holotype:  P or B-Willd.).  NOTE:  The type was not located among Kunth materials in herb. P or B-Willd by the first author in 1992.  However, Bentham (1875) noted that, "Kunth's specimen in the Paris Herbarium belongs to a form with rather small and narrow leaflets".
NOTE 2:  In response to the recent conservation of the type for Acacia with an Australian species, and both the desirability and timeliness of transferring species of the former subgenus Aculeiferum to the genus Senegalia, the fact that the name Acacia riparia Kunth has been used for this widespread species by most workers and that name is widely employed in floras of both Latin America and the United States, and in order to contribute to nomenclatural stability, we have made a proposal to conserve the name Acacia riparia Kunth in Humboldt, Bonpland, and Kunth (1823).  If accepted, the name for this taxon must become Senegalia riparia (Kunth) Seigler & Ebinger.

Acacia retusa (Jacq.) Howard, J. Arnold Arbor. 54:  435.  1973.  Mimosa retusa Jacq., Enum. syst.  pl. 34.  1760.  - TYPE:  none designated. NOTE:  The original description (Jacquin 1760) indicates that only a leaf fragment was used to describe this species.  This fragment is probably a specimen at BM.  According to Rudd (1976), a fruit was formerly associated with the specimen and the fruit is mentioned in a later description (Jacquin 1763).  The specimen at BM came from Cartagena, Colombia.  Neither description (Jacquin 1760, 1763) is adequate to identify the species being described.  With the materials available, we are unable to determine the status of the specimen from BM.  In the future, if adequate type material is located and this taxon is judged conspecific with Senegalia riparia, the name Mimosa retusa Jacq. will replace Acacia riparia Kunth as the basionym for this species.
Rudd (1976) located a specimen of Mimosa carthagenensis P. Miller ex auct. (1809), collected by Dr. Houstoun at Carthagena, Colombia, with both flowers and fruit at BM.  Based on the illustration from the article, she felt that this taxon was conspecific with A. retusa.

Mimosa sarmentosa Persoon, Syn. pl. 2:  266.  1807; Mimosa sarmentosa Desf., Tabl. ecole bot.  181.  1804, nom. invalid. (nom. nud.); Acacia sarmentosa Desv., Jour. Bot. 3:  70.  1814.  - TYPE:  no type cited.  NOTE:  Desvaux (1814) cites both Desfontaines (1804) and Persoon (1807).  Priority for nomenclature begins with Persoon (1807).  Persoon notes that this was a cultivated plant; Desvaux (1814) states that the plant was "cultivée dans le Jardin des Plantes", suggesting that the material studied by all three investigators was in the botanic garden in Paris, as all three lived there during this period.

Mimosa paniculata West, Bidr. Beskr. Ste Croix  312.  1793, nom. nud.; Mimosa paniculata West ex Vahl, Eclog. amer.  3:  39.  1807, nom. illeg., non Mimosa paniculata J. C.

Fl.  23:  119.  1928.  - TYPE:  VIRGIN ISLANDS.  Habitat in insula St. Crucis.  West s.n. (holotype:  not seen).  NOTE:  Mimosa paniculata J. C. Wendland (1798) is a species from the South Sea Islands.

Mimosa sarmentosa Sessé & Moc. Pl. nov. Hispan. 257.  1887.  - TYPE:  Habitat prope rivulos inter montium Tepalcatepec a Coahuayana separantium anfractus profluentes.  NOTE:  No type cited.
