OROZCO, CLARA INEacute;S  and  CANAL, DUBÁN. Cuatresia anomala and Cuatresia physalana (Physaleae, Solanaceae): two new species from Colombia and Ecuador. Caldasia [online]. 2011, vol.33, n.1, pp.79-89. ISSN 0366-5232.

Two new species of Cuatresia are described, Cuatresia anomala and Cuatresia physalana, distributed in the southwest of Colombia and the northwest of Ecuador. Cuatresia. anomala is the only species of the genus with sympodial unifoliate units, and the anthers with apparent poricide dehiscence; for this reason collections of this species were identified as the genera Lycianthes and Solanum. Furthermore, of the aforementioned characters, the laminae of the leaf is slightly asymmetrical, the inflorescence straight, long-pedunculate, the presence of a callus where the flowers are inserted, make this species distinguished from the rest of the species described in the genus. Cuatresia physalana is the only species of the genus with aristate plications in the accrescent calyx of the fruit, reminiscent of the accrescent calyx of species of Nicandra or Physalis, the zigzag pattern of the pendulous inflorescence, sessile or shortly pedunculate and the red or pink color of the fruit make of it different and easy to recognize.

Keywords : Cuatresia; new species; Solanacae; Physaleae; Flora of Colombia; Flora of Ecuador.
