“…The case of C. mennegae is an example of overlooked taxa and also highlights the collecting gaps in the Amazon. Similar floristic projects also reported dozens of new records and also overlooked species in the Amazon ( Barbosa-Silva et al, 2016 ; Sierra, Pereira & Zartman, 2019 ).…”

Christiana mennegae is a phylogenetically enigmatic taxon and represents a case in point of a species whose presence escaped the radar of the Amazon lists and the Brazilian Flora project. Here we expand its distribution by adding new records from Peru and overlooked ones from Brazil. To investigate its phylogenetic placement in the Brownlowioideae, part of the rbcL gene of the plastid and the intergenic ITS2 region were sequenced. Macro- and micro-morphological investigation of features of C. mennegae using SEM of foliar, flower, fruit and seed structures are presented. A lectotype for the name is designated here. The morphology of trichomes revealed five types of trichomes ranging from glandular to branched and unbranched and we also report stomata on the seed surface for the first time in Brownlowioideae. Christiana mennegae and C. africana were recovered as sister species in the phylogenetic analysis, albeit with low to moderate support, and more species of this and closely related genera must be sampled and analyzed in order to obtain a clearer picture of the group’s affinities and relationships. We provide an update of its conservation status from Vulnerable to Least Concern. We also highlight the need for investment in the digitization of biological collections, botanical capacity building at the local level and the importance of the availability of online literature to speed the study of Amazonian plant diversity.

“…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.…”

“…The biodiversity of Brioflora in the northern region is very diverse, but the issues of botanical identification and ecological importance are still poorly understood. The bryofloristic survey is a pioneering work necessary, in addition, to verify the component species of this region, which has been exposed to different anthropic actions, resulting in loss of biodiversity, is important to support conservation programs, management, environmental education, etc., since the Brazilian Amazon exists one of the richest floras in the world, which is distributed by vegetation complexes, which in turn are composed of different plant formations, which must be studied (SALDANHA, 2019;SIERRA;PEREIRA;.…”

This article is a literature review aimed at answering the following question: Over the past 30 years, research on bryophytes in northern states has intensified, allowing the identification and conservation of the biological diversity of bryophytes in this region. region? For data collection, we used the databases SCIELO, Google Scholar and sucupira platform. The inclusion criteria were defined as articles published between 1988 and 2018, and the exclusion criteria were articles from those 30 years old that were not located. States outside the northern region were excluded. Over the last 30 years, there were 186 scientific works, of which 58 articles were analyzed. Advances in Bryophyta research in the northern region are linked only to Brioflora's urban centers and surveys, so knowledge of the entire region is required for use in different areas of science.
