Abstract :

The authors describe and illustrate Racinaea pattersoniae as a new species of Ecuadorian Bromeliaceae, and also provide morphological data that distinguishes it from R. michelii (Mez) M.A. Spencer & L.B. Sm. and from R. tripinnata (Baker) M.A. Spencer & L.B. Sm. The most important morphological characteristics of R. pattersoniae vs. R. michelii are the abaxially glabrous leaf sheaths and the glabrous leaf blades, the imbricate peduncle bracts, the primary bracts which are longer than the stipes, the somewhat smaller flowers with floral bracts that are slightly shorter than the sepals and covered with ferruginous indument; vs. R. tripinnata are the erect rosette, the attenuate and recurved apex of the leaf blades, the long peduncle, the brown inflorescence, the small 4 mm long sepals ovate with a round and apiculate apex, and the small cream petals. Key words: Ecuador, Bromeliaceae, Racinaea, new species.
