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）项目的组成部分，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及馆藏于EAC、BHCB、HST、HVASF、RB和UFP标本馆的腊叶标本的形态性状分析。野外考察于2015年9月至2016年3月间开展。物种鉴定依据专业文献，并通过模式标本分析予以确认。在塞阿拉州共记录到远志科7属20种：刺枝属（Acanthocladus）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Securidaca属3种。上述物种分布于多种植被类型中，但偏好生长于卡廷加（caatinga）稀树草原与塞拉多（cerrado）稀树草原生境；其中13种（占比62%）被记录于5个保护单元内。莫氏远志（Monnina insignis）和鸡冠叶远志（Polygala celosioides）为塞阿拉州分布新记录种。
