VINCENT, P. L. D.&GETLIFFE, F. M., 1992.Elucidative studies on the generic concept ofSenecio(Asteraceae). This paper presents the results of studies of the generic conceptof Senecio sensu stricto.The sample of taxa studied consisted of 93 Natal senecios (including seven varieties and two forms), five Cape heterochromous senecios and nine non‐southern African senecios, including the type of the genus,S. vulgarisL. Also included in the study were six species from taxonomically closely related genera in the tribe Senecioneae and oneSenecioof uncertain taxonomic position. The phenotype of these taxa was investigated with respect to a large number (122) of morphological and micromorphological characters. Six characters were selected as being taxonomically important with respect to elucidating the generic concept ofSenecio sensu stricto.The generic concept ofSeneciohas been provisionally re‐circumscribed and the generic status of each of the senecios and non‐senecios studied has been tested according to this concept ofSenecio sensu stricto sensuVincent. In the light of this concept ofSenecio, the following species are recommended for exclusion fromSenecio sensu stricto sensuVincent:S. cissampelinus, S. transvaalensis, S. syringifoliusandS. hockii.The following species are considered to be peripheral toSenecio sensu stricto sensuVincent:S. tanacetopsis, S. seminiveus, S. medley‐woodii, S. tamoides, S. helminthioides, S. barbertonicus, S. brevilorus, S. viminalis, S. radicansandS.fulgens.Before any taxonomic changes are made to the current compositionof Senecio, the conceptof Senecio sensu stricto sensuVincent, is being tested on a worldwide sample of th
