A new genus,Votschia, based onJacquinia nemophila Pittier, is described and the new combinationVotschia nemophila (Pittier) Ståhl is made. The genus is known only from a small coastal area in northeastern Panama. It resemblesJacquinia in having flattened, petaloid staminodes andDeherainia in leaf morphology and corolla shape, but differs from both these genera in having the pollen exine fossulate-foveolate and the petiolar vascular bundles arranged in a circle. The two last-mentioned features are similar to conditions present in the three remaining genera of the family,Theophrasta, Neomezia, andClavija. Votschia differs from all other Theophrastaceae in its papillose young shoots and by having the abaxial leaf sclerenchyma arranged in a layer rather than in bundles.
