Resumo

Based on recent field work on an insular granitic outcrop in southeast Brazil, a new Tillandsia species was collected and described here. Tillandsia alcatrazensis belongs to T. subg. Anoplophytum and is morphologically similar to T. geminiflora, from which it differs by the larger size of the whole plant in flower, larger floral bracts and longer flowers with reddish-salmon sepals and white petals, and longer styles. We present a diagnosis, description, color photographs, illustration, ecological, and phenotypical variation comments, and compares it with the morphologically related species. Tillandsia alcatrazensis is preliminarily classified as Critically Endangered (CR) due to its small and restricted distribution, although the Alcatrazes Island is part of a national protected area.
