Abstract:—Recent history of studies in the Bromeliaceae, Pitcaimioideae is reviewed with emphasis on the changes since the 1974 monograph by L. B. Smith. A basic subdivision in the Pitcairnioideae, based on leaf cross-Section, first proposed in 1969, is reintroduced. The tribal divisions of Varadarajan and Gilmartin are dis cussed and rejected. Only two tribes are recognized, the Pitcairnieae (including the Brocchinieae and Puyeae) and a new tribe, Dyckieae. The latter is proposed for the series of genera lacking a sharp line of demarcation in leaf cross-Section between the chlorenchyma and adaxial water storage tissue, Deuterocohnia, Dyckia, Encholiriurn and Hechtia. Two keys are provided, one based primarily on traditional characters used by Lyman B. Smith, the other initially using the leaf cross-section to divide the subfamily into the Pitcaimieae and Dyckieae. Navia plosvinanii is transferred to $teyerbroinelia.
