ARIZA ESPINAR, Luis. Taxonomic notes on Senecioneae (Asteraceae) from Argentina. Bol. Soc. Argent. Bot. [online]. 2007, vol.42, n.3-4, pp.329-332. ISSN 1851-2372.

Some novelties have arisen through the analysis of the nomenclatural types during the study of tribe Senecioneae from Central Argentina. They are: 1.- Senecio pinnatus var. tenuisectus Griseb.: it was based upon 4 specimens which belong respectively, one to Senecio pinnatus Poir., two to S. pampeanus Cabrera, and the remaining to S. pampeanus fo. serratus Cabrera; 2 a .- Senecio gilliesianus Hieron. was based upon a specimen belonging to Senecio pampeanus Cabrera; 2b.- Senecio gilliesianus var. glaberrima Hieron. is a synonym of Senecio pinnatus Poir.; 3.- Senecio pampeanus fo. serratus Cabrera, is a synonym of S. pampeanus fo . pampeanus ; 4.- Werneria denticulata Blake is accepted as a synonym of W. pygmaea Gill. ex Hook. et Arn. as it was suggested by Rockhausen (1939), while the argentinean material identified under W. denticulata belongs to W. cochlearis Griseb.
