A syntaxonomical revision of the plant communities of the class occurring in Sardinia is provided. Within this class, the ephemeral herbaceous hygrophilous associations linked to temporarily submerged surfaces occur, which are widespread in the European, Mediterranean, and Macaronesian countries. It groups plant communities floristically characterized by a rich set of annual hygrophytes or more rarely hemicryptophytes and geophytes, which are also physiognomically, ecologically, and structurally well differentiated. Within this class, two orders are recognized in Sardinia, such as and , which are represented by several alliances. In particular, four alliances can be referred to as (, , and ), while a single alliance () belonging to has been identified. Within these alliances, several associations already described have been surveyed, while several other unpublished ones, are here proposed as new to science. Overall, 35 associations are recognized, 18 of which are described for the first time. Each higher-rank syntaxa and related associations are examined from a nomenclatural, floristic, ecological, and chorological point of view. In particular, the more significant phytosociological relevés regarding the examined associations were processed using cluster analysis, DCA ordination, optimclass diagram in order to highlight the correlations between them. As regards the floristic aspects, a checklist of the species occurring in the phytosociological relevés is provided.
本文对撒丁岛出现的该植物群落进行了植物分类学修订。在这个植物群落中，存在与暂时淹没的地表相关的一年生草本湿生植物群落，这些群落在欧洲、地中海和马卡罗尼西亚国家广泛分布。它将植物群落归为一类，这些群落的植物区系特征是有丰富的一年生湿生植物，或更罕见的半隐生植物和地下芽植物，在外貌、生态和结构上也有很好的区分。在这个植物群落中，在撒丁岛识别出两个目，如[具体目名1]和[具体目名2]，它们由几个群丛纲代表。特别是，有四个群丛纲可归为[具体群丛纲名1]（[具体群丛纲名1下属群丛1]、[具体群丛纲名1下属群丛2]、[具体群丛纲名1下属群丛3]和[具体群丛纲名1下属群丛4]），而已经识别出属于[具体群丛纲名2]的一个单一群丛纲（[具体群丛纲名2下属群丛1]）。在这些群丛纲中，已经对几个已描述的群落进行了调查，同时还提出了其他几个未发表的群落作为新的科学发现。总体而言，共识别出35个群落，其中18个是首次描述。从命名、植物区系、生态和分布学的角度对每个高级分类单位及其相关群落进行了研究。特别是，使用聚类分析、DCA排序、最优分类图对与所研究群落相关的更重要的植物社会学样方进行了处理，以突出它们之间的相关性。关于植物区系方面，提供了植物社会学样方中出现的物种清单。
