A morphometric study on Senecio apenninus and S. doronicum subsp. orientalis belonging to S. sect. Crociseris was carried out with univariate and multivariate analyses. In order to correctly classify these taxa and clarify the taxonomic value of S. apenninus, we studied 38 qualitative and quantitative morphometric characters from 85 herbarium specimens. The results of our analyses allow the recognition of two clearly distinct and separate taxa, distinguished by number and diameter of their capitula, the ratio of involucral bracts and supplementary bracts and length of supplementary bracts. Furthermore, a neotype for the name S. apenninus is selected.

Abstract
A morphometric study on Senecio apenninus and S. doronicum subsp. orientalis belonging to S. sect. Crociseris was carried out with univariate and multivariate analyses. In order to correctly classify these taxa and clarify the taxonomic value of S. apenninus, we studied 38 qualitative and quantitative morphometric characters from 85 herbarium specimens. The results of our analyses allow the recognition of two clearly distinct and separate taxa, distinguished by number and diameter of their capitula, the ratio of involucral bracts and supplementary bracts and length of supplementary bracts. Furthermore, a neotype for the name S. apenninus is selected.| File | Dimensione | Formato | |
