CALVINO, Carolina I.  y  MARTINEZ, Susana G.. New records from Argentina and Uruguay, and notes on Eryngium sect. Panniculata (Apiaceae). Darwiniana [online]. 2007, vol.45, n.1, pp. 68-76. ISSN 1850-1702.

Three species of Eryngium that constitute new records or problematic taxa for the Floras of Argentina and Uruguay are presented. E. balansae, known from Paraguay and Brazil, is recorded from Argentina for the first time. E. regnellii, originally described from Brazil, is recorded here from Argentina and Uruguay. This species, abundant in highlands of both countries, was in previously confused with E. stenophyllum in floristic and ecological studies. This last name designates an infrequent and poorly known species, and thus it is considered appropriate to here recharacterize it. For each of these three taxa a description, illustrations and a distribution map is provided, as well as a key to the Argentine species of Eryngium sect. Panniculata ser. Latifolia, the group to which the three entities belong.
