Reports for Bolívar and La Guajira Departments (Fryxell in Bernal et al. (2016: 1540)), probably are incorrect since material from those Departments deposited in the Herbario Nacional Colombiano (COL) is misidentified and should be referred to Bakeridesia integerrima (Hook. f.) D. M. Bates. Additional material examined. Colombia • Cundinimarca: Mpio. de La Mesa, “ Camino del Palmar, ” al SE de La Mesa, 1100–1300 m elev., 16 May 1952 (fl, fr), A. Fernández & L. E.

The specimen selected as lectotype of the name Abutilon petiolare was labelled by Kunth as “ Abutilon petiolare mihi ” and is part of the “ Herbier Humboldt & Bonpland. ” It also has flower, fruit and mature mericarps. The isolectotype specimen, part of Bonpland’s “ Herbier de l’Amérique équatoriale, ” was labelled “ Sida [illegible] ” and has a reference in an unknown hand to the publication (quarto edition) of A. petiolare. It has a fruit and a flower. This species lacks the horticultural appeal of other Callianthe species, yet it is distinctive. Pressed and dried material has a cinereous appearance; simple hairs on stems, petioles and pedicels are exceptionally long and visible without magnification; the leaf blade margin is coarsely serrate; leaf blade apices are long acuminate; petioles often clearly exceed leaf blades in length; and the petals are yellow.
