Abstract:—A checklist of the 11 genera and 16 species of Bromeliaceae from the Parque Estadual do Pico do Itambé in Santo Antônio do Itambé and Serra Azul de Minas, Minas Gerais, south-eastern Brazil, is presented. Bromelioideae is the most diverse subfamily and is concentrated in forested areas. Tillandsioideae and Pitcairnioideae are most abundant in elevated areas of campo rupestre vegetation. Vriesea medusa Versieux, a new night-blooming species belonging to section Xiphion (E.Morren) E.Morren ex Mez, was found in the area and is described and illustrated. It appears to be an endemic species distinguished from Vriesea nanuzae Leme by a combination of the usually larger dimensions in the rosette, the curved inflorescence which has lateral peduncles bearing up to five sterile bracts, the larger number of flowers, floral bracts and sepals that become dark purplish-brown towards the apex and the coloration of the leaves. Dyckia glandulosa L.B.Sm. & Reitz and Vriesea densiflora Mez, previously poorly known, were rediscovered and are depicted in their habitat for the first time. Vriesea procera var. tenuis L.B.Sm. is a new record for the state.?? 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158, 709?715.
