• Resumen

  • Aralia duplex (Araliaceae) is described as a new species from Pinar del Río Province, W Cuba, based on a specimen initially mistaken for A. rex. Only a single individual is known in the wild, in Viñales National Park, and no reproduction has been observed there. Differential characters include the leaflet margin, numbers of umbels per inflorescence and flowers per umbel, pedicel length, numbers of floral parts and fruit shape. Illustrations and distribution maps are provided. A key is presented for the identification of A. duplex and A. rex within A. sect. Sciadodendron. As with A. rex, the conservation status of A. duplex is assessed as Critically Endangered (CR). Ex-situ-germinated plants are being kept in cultivation by members of the Cuban Botanical Gardens Network.
