Manettia microcarpa Schum., described from the Coastal Cordillera of Venezuela, is scarcely to be separated from M. barbata Oersted, originally described from Costa Rica. The Costa Rican material of M. barbata that I have examined (Skutch 2902 from the vicinity of El General, Prov. San Jose) differs from the Venezuelan plants in having the stipule more elongated in the middle with a bicuspidate apex and more aculeate or erose margins, the calyx lobes relatively narrower or longer proportionately (1-1.5 × 1 mm) as compared with those of M. microcarpa (1.5-2 × 1.1-1.5 mm), and the inflorescence less branched and with fewer flowers (1-7) as contrasted with the more compoundly branched inflorescences with more numerous flowers (12-14 or more) of M. microcarpa. Both taxa have exceptionally short corollas 5-6.5 mm long, with the short tube 2.5 mm long shorter than the lobes, which are 3.5-4 mm long.
