Leaves: Leaves simple. Alternate. Blades pinnately divided. Pinnae larger and broader [than in C. grimesiana], laciniate, decurrent along the rachis. Base rounded or truncate. Margins dissected, segments coarsely dentate. Stipules absent.

Flowers: Flowers bisexual (perfect). Calyx 5-lobed, lobes 24-36 mm, dentiform, triangular, or oblong, rarely linear, distinct or rarely connate, tube cylindrical, adnate to ovary. Corolla zygomorphic, almost white; glabrous or pubescent, the tube suberect to strongly arcuate, dorsally cleft to about the middle, 7.5-12 times longer than the hypanthium, the dorsal lobes 35-40 mm long, as long as the tube to half again as long. Stamens 5, alternate with corolla lobes, connate; anthers 15-16 mm long and the ventral ones 12-14 mm long, dithecal, opening by longitudinal slits, coherent but separating after anthesis or connate and forming a tube into which pollen is shed; filaments distinct or connate above, attached to the epigynous nectary disk or to base of corolla, rarely adnate to corolla tube. Ovary inferior, 2-celled; ovule placentation axile; stigma 2-lobed, wet or dry, appressed and nonreceptive as the style grows through the anther tube, pushing out the pollen, after which the stigmas spread apart and become receptive.
