Abstract

Two new Colombian species were identified in the Neotropical genus Symbolanthus (Gentianaceae: Helieae) during an ongoing revisionary study. Symbolanthus pterocalyx Struwe is characterized by its green to yellow corollas, strongly winged stems, and long-acuminate calyx lobes with a long, thin dorsal keel on each lobe. The other new species, Symbolanthus tetrapterus Struwe, also has strongly winged stems, but corollas variously colored in green, white, pink, to red-violet and calyx lobes rounded and non-keeled. Both species are endemic to small areas in the Andes of western Colombia. The western outlier Cerro del Torrá of the Cordillera Occidental in the province of Chocó (Colombia) is the only known locality of Symbolanthus tetrapterus. Symbolanthus pterocalyx occurs in high-elevation cloud forests, subpáramo, and páramo in a small area around Medellín in the province of Antioquia (Colombia).
