Notes:

This species is characterized by its villous to hirsute or tomentose pubescence, its subsessile to shortly petiolate leaves with a pair of swollen ant vesicles at the base of the blade or along the upper part of the petiole; its subcapitate to corymbiform inflorescences with the axes generally becoming scorpoioid, its well developed calyx lobes, and its relatively large yellow corollas. The vesicles appear to be formed by a broadened basal portion of the leave blade about 1-3 cm long that is strongly revolute, forming a closed or nearly closed structure about 0.5-1 cm wide; at least sometimes these structures house ants. The calyx lobes and corolla are notably large for Hoffmannia.

Hoffmannia formicaria is one of eight Hoffmannia species with ant vesicles found in Costa Rica, Panama, and adjacent northwestern Colombia. These share the characterisic pubescence, vesicles at the base of the leaf blade, and generally well developed inflorescences; however they vary in details of the inflorescence arrangement, leaf form and size, and calyx, corolla, and fruit details. The species and their distinctions are outined in the key to the vesiculate Central American Hoffmannia species on the species page for Hoffmannia vesciculifera.

Distribution: Wet vegetation at 700-1900 m, western Panama.
