A valid name for the taxon known as Tillandsia bryoides auct: Bromeliaceae

tillandsia bryoides was sunken into the synonmy of t. tricholepis because all the elements of the lectotype (p. lorentz 128, bm) belong to the latter species. however, there are many vouchers from different herbaria (some of them cited as reference material in several publications) previously identified as t. bryoides, that in fact correspond to a new species of tillandsia subgen. diaphoranthema. this new species has yellow, sessile, solitary flowers and a glabrous floral bract, and grows in central peru, bolivia, and central and northwestern argentina. this paper provides a valid name for this species, an illustration, distribution data, and a discussion of the relationships with its morphologically closest species.
