Phylogeny and evolution of Dyckia (Bromeliaceae) inferred from chloroplast and nuclear sequences

Plant Systematics and Evolution, 2014
The genus Dyckia (Bromeliaceae) comprises more than 150 terrestrial or epilithic species with a strongly xeromorphic habit. Most of its members belong to the azonal rock vegetation of Neotropical savannas and forests of Brazil and adjacent countries.

Structural anomalies in pollen grains of Dyckia racinae L.B.Sm. (Bromeliaceae)

Brazilian Journal of Botany, 2020
The development of the pollen grains is a complex and regulated process. However, failures in sporogenesis and gametogenesis are common and include cell division errors and multiple structural modifications, culminating usually in abortions or, less frequently, in formation of anomalous pollen grains.

Leaf morphoanatomy of the rheophyte Dyckia distachya Hassler (Bromeliaceae)

2009
This research reports on the leaf morphoanatomy of the rheophyte Dyckia distachya. Plants with young and mature leaves of three populations from the Pelotas River and Uruguay River (SC, Brazil), which were maintained in a greenhouse, were utilized in the study. The leaves of D. distachya have sheaths, and the blades are lanceolate with serrate margins.

Dyckia inflexifolia(Bromeliaceae), a New Species from Brazil

Annales Botanici Fennici, 2012
A new species, Dyckia inflexifolia Guarconi & MA. Sartori (Bromeliaceae), is described and illustrated as a species restricted in the ferruginous rocky soils vegetation in the municipality of Serro, Minas Gerais, Brazil. The new species forms a complex with D. ursina and D. sordida, being compared to the latter, to which it appears most closely related.

Ex situ conservation of Dyckia distachya on South Brazil

The Brazilian Atlantic Forest biome contains a high level of genetic diversity. Historically, several factors have contributed to the drastic reduction of its coverage, which is now restricted to less than 7%. Large forest areas have been cut down in Santa Catarina and Paraná states to make way for hydroelectric power plant dams, and many plant species
