| Abstract: | A new species, Tropaeolum sparrei Ståhl (Tropaeolaceae), is described from submontane cloud forest habitat in western Ecuador. It differs from T. papillosum Hughes (the species it resembles most) by having thinner, tomentose stems, smaller, glabrous or subglabrous leaves with the petiole inserted relatively closer to the lower leaf margin, and flowers with uniformly coloured and straight calyx spurs. In leaf shape it is also similar to T. repandum Heilborn, from which it differs in its larger flowers with entirely black petals and blue anthers. |
