Two new species of Rubus L. (Rosaceae) from the western Andes of Ecuador

Abstract:

Two new species of Rubus (Rosaceae) from the western Andes of northern Ecuador are described. Rubus longistipularis D.A. Espinel-Ortiz & Romol. is a scandent or climbing shrub found in the mountain forests of Chocó Andino from northern Ecuador. Rubus maquipucunensis D.A. Espinel-Ortiz & Romol. is a vine or climbing shrub found in the rainforests of Chocó Andino from Pichincha and Santo Domingo de los Tsáchilas. The species mentioned here are morphologically differentiated from all the Rubus species from Ecuador with a detailed botanical description, illustrations and photographs. We also report, for the first time, possible hybridisation between R. longistipularis and R. boliviensis Focke, as the samples reviewed showed mixed characteristics from both species.
