Morphological Variation in the Vriesea procera Complex (Bromeliaceae, Tillandsioideae) in the Brazilian Atlantic Rainforest, with Recognition of New Taxa

Systematic Botany, 2020
The family Bromeliaceae is essentially Neotropical, with high endemism and diversity in the Atlantic Rainforest Domain. Species circumscription is a major problem in the family systematics, especially in the most diverse genera.

Identification of potential miRNAs and their targets in Vriesea carinata (Poales, Bromeliaceae)

Plant Science, 2013
The miRNAs play important roles in regulation of gene expression at the post-transcriptional level. A small RNA and RNA-seq of libraries were constructed to identify miRNAs in Vriesea carinata, a native bromeliad species from Brazilian Atlantic Rainforest.

Anatomical and physiological changes of in vitro-propagated Vriesea imperialis (Bromeliaceae) in the function of sucrose and ventilated containers

Plant Biosystems, 2019
Under in vitro culture conditions, plants may present physiological and anatomical disorders, which can interfere negatively after ex vitro transfer. The aim of this investigation was to analyze the impacts of natural ventilation and sucrose supply on ...

Does oxidative stress determine the thermal limits of the regeneration niche of Vriesea friburgensis and Alcantarea imperialis (Bromeliaceae) seedlings?

Journal of Thermal Biology, 2019
The predicted environmental changes may be detrimental to initial seedling growth, particularly the expected increase in air temperature. We therefore investigated the thermal limits for growth and development of Vriesea friburgensis and Alcantarea ...

Nomenclature and epitypification of Vriesea (Bromeliaceae) species described in Vellozo’s Flora fluminensis

Phytotaxa, 2018
In the eighteenth century, José Mariano da Conceição Vellozo in his work Flora Fluminensis, sought to expand the floristic knowledge of Rio de Janeiro and surroundings. This was the first flora of Brazil written and edited by a native naturalist. However, the existence and location of the type material of species described in this work are not known ...

Species Boundaries in the Vriesea incurvata (Bromeliaceae) Complex After a Broad Morphometric and Taxonomic Study

Systematic Botany, 2018
The genus Vriesea encompasses many species of difficult delimitation, including Vriesea incurvata, which shows wide morphological variation throughout its distribution in the Brazilian Atlantic Forest.

Evolution of Mesic and Xeric Habits in Tillandsia and Vriesea (Bromeliaceae)

Systematic Botany, 1983
Species of Tillandsioideae are usually epiphytic and portray a range of habits from st.rongly xeric with thick, narrow leaves that are densely covered with conspicuous, shield-shaped, moisture-absorbing trichomes to mesic with broad, thin leaves having few and inconspicuous trichomes.
