Biodiversity and Conservation of Plants in Brazil
TLDR
Coordinated efforts to catalog Brazil's flora are in progress and include projects such as the conservation priority-setting workshops of the Brazilian Ministry of the Environment; development of threatened species lists for plants; and the assembly of type data on species of northeastern Brazil through the Darwin Initiative, which greatly assist in increasing knowledge.
Molecular phylogenetics of the Brazilian giant bromeliads (Alcantarea, Bromeliaceae): implications for morphological evolution and biogeography.
TLDR
Spreading stamens, a morphological floral characteristic assumed to be related to Chiropterophily, apparently evolved multiple times within the genus Alcantarea, and invasion of rocky savanna-like habitat vegetation by Atlantic rainforest ancestors seems to have occurred multiple times as well.
Chromosome number of Orthophytum species (Bromeliaceae)
TLDR
Meiotic and mitotic chromosome numbers of 12 species of this important genus in Bromeliaceae are presented and polyploidy seems to play an important role in chromosome evolution associated with habitat differentiation among diploid andPolyploid species.
Vriesea (Bromeliaceae, Tillandsioideae): taxonomic history, and morphology of the Brazilian lineage1
TLDR
This work presents a morphological description of the species from the Brazilian lineage of the Vriesea genus, and the taxonomic history of the genus, based on extensive bibliographic research and morphological analyses of herbarium material and living specimens.
Alcantarea (Bromeliaceae) leaf anatomical characterization and its systematic implications
Alcantarea (Bromeliaceae) has 26 species that are endemic to eastern Brazil, occurring mainly on gneiss–granitic rock outcrops (‘inselbergs’). Alcantarea has great ornamental potential and several
Molecular phylogeny of the Brazilian endemic genus Orthophytum (Bromelioideae, Bromeliaceae) and its implications on morphological character evolution.
TLDR
The phylogenetic reconstruction revealed a well-supported clade termed Eu-Orthophytum, containing species with pedunculate inflorescences only, and the subgroup mello-barretoi was sister to the most diversified clade, termed Core OrthophyTum.
Two new species of Alcantarea (Bromeliaceae, Tillandsioideae) from Brazil
Alcantarea turgida andA. tortuosa are described and illustrated as new species from southeastern Brazil. The relationships ofA. turgida withA. extensa and withA. vinicolor and ofA. tortuosa withA.
Dyckia tubifilamentosa (Pitcairnioideae-Bromeliaceae): a new species from Northeastern Brazil
TLDR
Dyckia tubifilamentosa Wand is found in some areas of the semiarid region of Northeastern Brazil (Piaui State), growing in the Caatinga and transitional Caatesa-Cerrado biomes.
Alcantarea pataxoana (Bromeliaceae), a New Species from Bahia, Brazil
TLDR
The new species is the second taxon of this genus recorded for the flora of the state of Bahia, northeastern Brazil, and its differences from A. nahoumii are highlighted in an updated taxonomic key for that state.
An illustrated checklist of Bromeliaceae from Parque Estadual do Rio Preto, Minas Gerais, Brazil, with notes on phytogeography and one new species of Cryptanthus
TLDR
The cluster analysis indicated that the Rio Preto State Park has a Bromeliaceae flora more similar to that from Pico do Itambe and Grao Mogol State Parks, which highlights the importance to create a corridor joining these neighboring reserves to connect populations of narrowly ranged or rare species.
