A morphometric (multivariate and univariate) and karyological study of Onobrychis calabrica Sirj. (Fabaceae), compared to O. alba subsp. echinata (Guss.) P. W. Ball and O. supina (Chaix ex Vill.)

In addition, the latter species is tetraploid with 2n = 4x = 28 chromosomes, whereas the other two taxa are diploid with 2n = 2x = 14 chromosomes. The names O. calabrica and O. handel-mazzettii Sirj.

Onobrychis calabrica, a narrow endemic to SE Calabria, S Italy, is here assessed as Critically Endangered CR B1ab(iii)+B2ab(iii) following IUCN Red List categories and criteria.

Abstract

A morphometric (multivariate and univariate) and karyological study of Onobrychis calabrica Sirj. (Fabaceae), compared to O. alba subsp. echinata (Guss.) P. W. Ball and O. supina (Chaix ex Vill.) DC., was carried out. According to our results, twelve morphological characters clearly support the distinctiveness of O. calabrica. In addition, the latter species is tetraploid with 2n = 4x = 28 chromosomes, whereas the other two taxa are diploid with 2n = 2x = 14 chromosomes. The names O. calabrica and O. handel-mazzettii Sirj. (a heterotypic synonym of O. supina) are lectotypified here. Onobrychis calabrica, a narrow endemic to SE Calabria, S Italy, is here assessed as Critically Endangered CR B1ab(iii)+B2ab(iii) following IUCN Red List categories and criteria.
