[Botany • 2017] The Restablishment of Dyckia oligantha and D. nana (Bromeliaceae, Pitcairnioideae), Belonging to the D. macedoi Complex



Abstract

The authors reestablish Dyckia oligantha and D. nana, considered synonymous of D. saxatilis and D. macedoi, respectively, on the basis of newly collected specimens from the type localities. Multivariate analysis of vegetative and reproductive characters on natural populations of the species of the D. macedoi complex were performed, allowing the recognition of D. macedoi, D. nana and D. oligantha as distinct species.

Keywords: “Campos rupestres”, morphometry, taxonomy, rocky fields, species complex, Monocots
