Taxonomic review of the Dyckia remotiflora complex (Bromeliaceae, Pitcairnioideae)
PhytotaxaSeveral species complexes of Dyckia s.s. have been investigated in recent years, with the taxonomy of the genus regarded as one of the most challenging within the family. In this study, we propose the circumscription of the Dyckia remotiflora complex and present a taxonomic-nomenclatural revision for the included taxa: D. remotiflora var.

Structural anomalies in pollen grains of Dyckia racinae L.B.Sm. (Bromeliaceae)
Brazilian Journal of Botany, 2020The 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.
