Plant Systematics and Evolution, 2002
The reproductive biology of three sympatric species Pitcairnia flammea, P. corcovadensis and P. albiflos (Bromeliaceae) was studied on Corcovado Mountain in the city of Rio de Janeiro, Brazil. Controlled pollination experiments were also conducted using plants transplanted to a greenhouse.

Pitcairnia kranziana Leme 2025, sp. nov.
Pitcairnia kranziana Leme, sp. nov. (Fig. 16 A–N) Diagnosis:––This new species is closely related to Pitcairnia torresiana L.B. Smith (1952: 4), but differs from it by leaves monomorphic (vs. dimorphic), the outer ones narrowly triangular-lanceolate (vs. filiform), and leaf blades broader (12–18 mm vs.Leme, Elton M.

A multivariate analysis of the Pitcairnia palmeri group (Bromeliaceae: Pitcairnioideae)
Phytotaxa, 2018A multivariate analysis of the Pitcairnia palmeri group are presented. Principal Components and Cluster analyses were performed in order to have more accurate information to delimit the species. The analyses showed that the specimens referred to Pitcairnia palmeri var. longebracteata are clearly delimited, while those identified as P.

We investigated pollination biology and breeding systems in hybridizing populations of Pitcairnia albiflos and P. staminea; both species are endemic to rocky outcrops at Rio de Janeiro, Brazil. These species are morphologically distinct and easily recognized by floral color: white in P. albiflos and red in P. staminea.
