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.

意大利卡拉布里亚一种被忽视的特有物种——卡拉布里亚石斛的形态计量学和核学研究

calabrica的形态学(多变量和单变量)和核学研究。(豆科)，与O. alba亚种相比。echinata(连)。P. W. Ball和O. supina (Chaix ex ville)直流。，被执行。根据我们的研究结果，12个形态特征清楚地支持了仙人掌的独特性。另外，后一种是四倍体，2n = 4x = 28条染色体，而另外两个分类群是二倍体，2n = 2x = 14条染色体。O. calabrica和O. handel-mazzettii Sirj。(O. supina的异型同义)在这里被选型。卡拉布里亚Onobrychis calabrica是意大利南部卡拉布里亚东南部的一种狭窄的特有物种，根据IUCN红色名录的分类和标准，在这里被评估为极度濒危CR B1ab(iii)+B2ab(iii)。

期刊介绍： Willdenowia is an international peer-reviewed journal publishing original research articles in English from the entire fields of plant, algal and fungal systematics, covering the evolution, taxonomy and nomenclature of these organisms as well as related fields such as floristics and plant geography. Articles on phylogeny and molecular systematics are especially welcome, as are review articles. Descriptions of new taxa may be considered, but only if supported by robust evidence. Narrowly regional studies of widespread taxa, routine typifications, checklists and new floristic records are generally not considered (excluding contributions to the Euro+Med-Checklist Notulae). Authors are encouraged to deposit duplicates of their material, especially nomenclatural types, in the Berlin herbarium (B).
