Abstract

A new species of bromeliad, Tillandsia uiraretama, is here described and illustrated. Tillandsia uiraretama was discovered during fieldwork on an insular granitic outcrop in southeast Brazil. The proposed taxon belongs to T. subgenus Anoplophytum and is compared to the morphological related T. araujei, T. aeranthos, T. iassuensis, and T. tenuifolia. It differs from them by the unique combination of fertile portion of the inflorescence with 4-7.5 cm long, 8 to 16 flowers per inflorescence, flower length of 3-3.4 cm, floral bract length of 1.7-3.8 cm, petal lilac with 2.7-3.4 cm long and 0.8-0.9 cm wide, stamen length of 1.5-1.9 cm and style length of 1.8 cm. A preliminary conservation assessment classifies T. uiraretama as vulnerable (VU). (AU)
