摘要

摘要本文对巴西米纳斯吉拉斯维纳萨地区Didymochlaenaceae和Dryopteridaceae两种植物进行了分类研究。本研究基于来自IAN, K, NY, PACA, RB, SP, UPCB, US和VIC的50个植物标本收集。Didymochlaenaceae以Didymochlaena truncatula为代表，而Dryopteridaceae则有7属11个属内分类群:Ctenitis(4个分类群，包括2个变种)、Megalastrum(2种)、Mickelia、Parapolystichum、Polybotrya、Rumohra和stimatopteris(各1种)。在这里发现的12个矮属分类群中，有7个是巴西大西洋森林特有的。本研究首次在维萨罗萨报道了桔梗、黄芪、斑蓼。识别密钥，描述，插图，地理分布和评论呈现给所有分类群。

Ferns of Viçosa, Minas Gerais, Brazil: Didymochlaenaceae and Dryopteridaceae

Abstract We present a taxonomic treatment for the species of Didymochlaenaceae and Dryopteridaceae occurring in the region of Viçosa, Minas Gerais, Brazil. This study was based on 50 herbarium gatherings from IAN, K, NY, PACA, RB, SP, UPCB, US, and VIC. Didymochlaenaceae is represented by a single species, Didymochlaena truncatula, whereas Dryopteridaceae has 11 infrageneric taxa in seven genera: Ctenitis (four taxa, including two varieties), Megalastrum (two species), Mickelia, Parapolystichum, Polybotrya, Rumohra, and Stigmatopteris (one species each). Among the 12 infrageneric taxa here recognized, seven are endemic to the Brazilian Atlantic Forest. Ctenitis distans var. isabellina, Megalastrum connexum, and Polybotrya speciosa are here reported for the first time in Viçosa. Identification keys, descriptions, illustrations, geographical distribution, and comments are presented to all taxa.
