Notes:
This species is characterized by its slender twining habit, rather small (for Manettia) thin-textured leaves, few-flowered short cymes with regularly developed slender pedicels, triangular to ligulate calyx lobes 1.5-2 mm long, tubular-funnelform white corollas with tubes 5-8 mm long and lobes ca. 2-2.5 mm long, and small to medium-sized subglobose capsules. Manettia jorgensenii is similar to Manettia fiebrigii central to southern Bolivia, which has corolla tubes usually a little longer; these could be a clinal set of forms rather than distinct species.
