Abstract

In Europe, the genus Bolboschoenus has recently undergone many taxonomic revision studies, but in Italy a review of the materials conserved in herbaria, in accordance with the most recent taxonomic literature, was still missing. The aim of this study was therefore to review Bolboschoenus species from Italy, based on herbarium data. The specimens deposited in the main Italian herbaria were analyzed by a morphometric study, based on measurements and statistical analyses of the characters most commonly used in the updated taxonomic literature. Moreover, an analysis of the national distribution of the resulting species was carried on, also taking into account Italian data from international herbaria, previously used in specialist works. The study confirmed the diagnostic importance of some traits related to the achene morphology and anatomy, in particular the ratio between mesocarp and exocarp. On the other hand, some inflorescence-related characters, which were commonly used in the past, proved to have less discriminant power. The study revealed various distribution novelties, also with respect to the most recent national botanical literature. Finally, B. yagara was reported for the first time in Italy.

摘要

在欧洲，Bolboschoenus属最近经历了许多分类学修订研究，但在意大利，根据最新的分类学文献，对植物标本馆保存的材料的审查仍然缺失。因此，本研究的目的是回顾Bolboschoenus来自意大利的物种，基于植物标本馆的数据。基于更新的分类文献中最常用的特征的测量和统计分析，通过形态测量研究分析了存放在主要意大利植物标本馆的标本。此外，还对所得物种的全国分布进行了分析，同时还考虑了以前用于专业工作的国际植物标本馆的意大利数据。该研究证实了与瘦果形态和解剖结构相关的一些性状的诊断重要性，特别是中果皮和外果皮之间的比率。另一方面，一些过去常用的与花序相关的字符被证明具有较低的判别力。该研究揭示了各种分布新颖性，也关于最近的国家植物学文献。最后，B. yagara首次在意大利报道。
