T. glandulosa Gleason, Bull. Torrey Club 58: 252. 1931.

Klug 424 and Asplund 14596 cannot be distinguished from the Poeppig collections (2549, 2790, Addenda 180, W); all have (despite Cogniaux' description) styles moderately puberulous with slender hairs and the minutely conical ovary apex with about 10 delicate glandular setae 1-1.5 mm long. To T. egensis, I have tentatively referred a large series of Amazonas (Venezuela) specimens with sparsely glandular-setulose external calyx teeth up to 4 mm long and sparsely glandular-setose hypanthia. I seriously doubt that T. longisepala Cogn. should be maintained apart from T. egensis; although the Spruce type collections (K, W) show no trace of hypanthial or calycine setae, there seem to be no other differences from the Venezuelan material. The establishment of subspecific status for T. longisepala under T. egensis would require critical examination of priornamed species—T. coronata Benth. and T. truncata Benth.—as well as the species of Tococa Sect. Anaphysca with puberulous styles and ovaries.
