Type. Petals deep pink, anthers yellow, frequent in swampy depression in savanna along east branch of headwaters of Rio Tirica, central section of Chimanta Massif, Edo. Bolivar, Venezuela, alt. 2100 m, 12 Feb 1955, J. A. Steyermark & J. J. Wurdack 766 (holotype U S 2342408). Paratypes: VENEZUELA, Edo. Bolivar. Chimanta IMassif: savanna below summit of western escarpment, Torono-tepui, alt. 2100 m, Steyermark & Wurdack 679; east-central portion of summit of Apacara-tepui, alt. 2150-2200 m, Steyermark 75882.

The tepui species of Comolia have similar stamens, but qualitatively very different pubescence and a two-celled ovary. The species of Acisanthera Sect. Acisanthera have 3-locular ovaries, but predominantly 5-merous flowers with definitely bilobed ventral connective appendage and non-woolly pubescence; the species are herbaceous or scarcely woody.
