Novelties in the genus Tillandsia (Bromeliaceae, Tillandsioideae) for Uruguay

Abstract

Tillandsia capillaris Ruiz & Pav. ( = T. capillaris f. hieronymi (Mez) L.B. Sm.) and T. loliacea Mart. ex Schult. are reported for the first time for the flora of Uruguay. Tillandsia capillaris is registered as an introduced and spontaneous species for Montevideo city, while T. loliacea is cited as native for northwestern Uruguay. Tillandsia tricholepis Baker is reported for the first time for natural environments in Uruguay, establishing its status as native. The recent finding of Tillandsia xiphioides Ker Gawl in Uruguay is reported after 73 years without being collected. We provide morphological descriptions, distribution and habitat data, phenology, conservation assessment, and images for each species treated.
