Abstract

Recebido em 12/10/2011. Aceito em 18/06/2012 RESUMO(Taxonomia e distribuição de Cheilolejeunea aneogyna (Spruce) A. Evans (Lejeuneaceae, Marchantiophyta)). Cheilolejeunea aneogyna (Spruce) A. Evans é uma espécie sul americana, ocorrendo nas Florestas Amazônica e Atlântica. Caracteriza-se, principalmente, pela presença do segundo e primeiro dentes do lóbulo contíguos um ao outro e ausência de inovações. Entre as espécies neotropicais, C. aneogyna é a única que pode apresentar ocelos, porém, a presença destes não é constante. Descrição, ilustração, comentários sobre a morfologia e distribuição geográfica são fornecidos e discutidos. Está sendo referida pela primeira vez para a Bolívia.Palavras-chave: Briófitas, Hepáticas, Lejeuneoideae, Neotrópico, Bahia ABSTRACT (Taxonomy and distribution of Cheilolejeunea aneogyna (Spruce) A. Evans (Lejeuneaceae, Marchantiophyta)). Cheilolejeunea aneogyna (Spruce) A. Evans is a South American species found in the Amazon and Atlantic Forest. It is characterized mainly by the presence of the first and second teeth of the lobule that are adjacent to each other and the lack of innovations. Among the neotropical species, C. aneogyna is the only one that has ocelli; however, their presence is not constant. A description, illustration, and comments on the morphology and geographic distribution are provided. This species is reported for the first time for Bolivia.

Briology studies in the northern region

“…Over the years research on this theme has grown in these states, and in the Amazon this scenario has been updated by recent publications of new occurrences for the region (CARDOSO et al, 2015;BASTOS;ZARTMAN, 2017), were also collected and described new species (MOURA; ILKIU-BORGES, 2012;BASTOS;ZARTMAN, 2016;SIERRA et al, 2019). Even so, it is necessary to produce knowledge about the diversity of species and their habits, based on the implementation of public policies and the creation of preserved areas in order to support the genetic information of the species of bryophytes.…”

Cheilolejeunea zhui (Lejeuneaceae, Marchantiophyta), a new species with moniliate ocelli from Guangxi, China

“…Ocelli are usually lacking in Cheilolejeunea species, with only a few exceptions (Gradstein, 2013;Zhu et al, 2002), e.g., in C. aneogyna (Spruce) A. Evans, C. insignis, C. falsinervis, C. urubuensis, and the present species. The presence of ocelli in C. aneogyna is not constant, 2-3 per leaf lobe when present, basal form (Bastos, 2012).…”

“…Ocelli are usually lacking in Cheilolejeunea species, with only a few exceptions (Gradstein, 2013 ; Zhu et al, 2002 ), e.g., in C. aneogyna (Spruce) A. Evans, C. insignis , C. falsinervis , C. urubuensis , and the present species. The presence of ocelli in C. aneogyna is not constant, 2–3 per leaf lobe when present, basal form (Bastos, 2012 ). Ocelli in other ocellate Cheilolejeunea species are arranged in linear form (He & Piippo, 1999 ), and occur continuously and longitudinally from leaf base to at least the middle of the leaf lobe.…”
