Interspecific hybridization between Pitcairnia albiflos and P. staminea (Bromeliaceae) was investigated using morphometric analysis. Nine morphological traits representing inflorescence size and flower shape were recorded for different plants in a mixed population at Pão de Açúcar, Rio de Janeiro, Brazil in 1996. Examination of the morphometric variables using Analysis of Variance (ANOVA) and Discriminant Function Analysis supported a hypothesis for the existence of naturally occurring hybrids that are intermediate and distinct from the parental species.
