Tillandsia bandensis (Bromeliaceae): its lectotypification and a new subspecies from Uruguay

A new epilithic subspecies of Tillandsia bandensis (Bromeliaceae) is described based on the analysis of herbarium specimens as well as living plant material in the field and in cultivation. The new subspecies differs from the typical one mainly by its bigger and more lepidote reproductive structures. Detailed morphological descriptions for T. bandensis and its subspecies are provided, as well as images, illustrations and data on distribution, habitat, phenology and conservation status for the new subspecies here described. Lectotypes for T. bandensis, T. bandensis var. intermedia and T. recurvata var. majuscula are designated.
