Solanum edmundoi (Solanaceae), una especie nueva de bejuco con aguijones del occidente de México

A new species of Solanum from Sierra de Cacoma, a little known and explored floristic region in Western Mexico, is described and illustrated. Solanum edmundoi should be placed in section Aculeigerum, on account of its scandent habit, recurved prickles on stems and leaves, and indument with septate simple hairs and slightly attenuated anthers. It differs from related species by the type and consistency of the leaves, the color of the flowers, stamens of equal size, short filaments and color of the fruits. A key is provided to separate it from its closest relatives.
