Flora of Ceará, Brazil: Polygalaceae

Abstract This study aimed carry out the floristic inventory of Polygalaceae species, as part of Flora of Ceará project. The study was based in the analysis of morphological characters of specimens obtained in field or in herborized collections from herbaria EAC, BHCB, HST, HVASF, RB and UFP. The field expeditions were realized between September/2015 and March/2016.. The identifications were based on specialized bibliography, confirmed by analysis of collections-types. In the Ceará State, 20 species and seven genera were registered: Acanthocladus (1) Asemeia (3), Bredemeyera (2), Caamembeca (1), Monnina (1), Polygala (9) and Securidaca (3). The species were registered in distincts vegetation types, but occurs, preferably, in stepic savannah (caatinga) and savannah (cerrado) and 13 (62%) were recorded in five Conservations Units. Monnina insignis and Polygala celosioides are new records for Ceará state.

摘要 本研究作为塞阿拉州植物志（Flora of Ceará）项目的一部分，旨在开展远志科（Polygalaceae）物种的区系调查。本研究基于对野外采集标本及EAC、BHCB、HST、HVASF、RB、UFP等标本馆馆藏腊叶标本的形态性状分析完成。野外考察于2015年9月至2016年3月期间开展。物种鉴定以专业文献为依据，并通过模式标本分析予以验证。本次调查在塞阿拉州共记录到远志科7属20种：Acanthocladus属（1种）、Asemeia属（3种）、Bredemeyera属（2种）、Caamembeca属（1种）、Monnina属（1种）、远志属(Polygala)（9种）以及蝉翼藤属(Securidaca)（3种）。上述物种分布于多种植被类型中，尤以卡廷加（caatinga）干旱稀树草原和塞拉多（cerrado）热带稀树草原最为常见；其中13种（占比62%）被记录于5个保护单元内。显眼莫纳远志(Monnina insignis)和鸡冠花状远志(Polygala celosioides)为塞阿拉州植物分布新记录种。
