Abstract:—Dyckia semperflorens (Bromeliaceae: Pitcairnioideae) is described as a new species from the temperate climate region of Rio Grande do Sul state, southern Brazil. The new species belongs to the Dyckia encholirioides complex and is closely related morphologically to Dyckia monticola, which is endemic to the Quiriri mountain range, a high-altitude region in the northeastern part of Santa Catarina state. Dyckia semperflorens is distinguished by having basal floral bracts of the main inflorescence axis exceeding the length of the flowers, flowers 2.3?2.5 cm long, anthers prior to dehiscence 4.5?5.0 ? 1.5?1.6 mm, and stigmatic margins without trichomes. The new species is only known from a single population on a rocky escarpment on the banks of the Touros River and is assessed as ?Data Deficient' (DD) based on the IUCN criteria.
