Description
Species Description - Shrub or subshrub 1-3 m tall; the branchlets subtetragonal, tending to be somewhat 4-sulcate, tannish-tomentose with stellate trichomes. Leaves 5-foliolate, the leaflets oblong-obovate to narrowly elliptic-oblong or oblanceolate, obtuse to acutish at apex, the base broadly cuneate to asymmetrically truncate, 4-25 cm long, 1-9 cm wide, entire, coriaceous, the tertiary venation subappressed above, hardly apparent below from the very dense tomentum, above slightly lepidote, sparsely stellate puberulous mostly near the main veins, below very densely stellate-tomentose, drying strongly discolorous, dark olive above, pale tan below; petiole 3-25 cm long, longitudinally striate-ridged, densely tannish stellate, the petiolules 0-5 cm long, the lateral pair usually very reduced. Inflorescence a dichotomously branching terminal panicle with a well-developed central axis, stellate-tomentose, each dichotomy subtended by a puberulous linear bract 0.5-2 cm long. Flowers tannish or brownish outside, yellow inside, the calyx irregularly 2-3-dentate, bilabiately split to near base on at least one side, 12-20 mm long, densely tannish stellate tomentose; corolla rather thick, tubular-cylindric, the tube very slightly narrowed toward base, 2.5-5 cm long, 0.7-1.5 cm wide at mouth of tube, the tube 2-4 cm long, the lobes 0.5-1 cm long, narrow and almost valvate in bud, tube and lobes densely stellate tomentose outside, inside mostly glabrous, stiff-pilose at stamen insertion, also papillose-surfaced below insertion; filaments sparsely pilose, the bases expanded and more densely pilose, the anthers subexserted, slightly divergent, pendulous, ca. 3 mm long; ovary ellipsoid above a 2-3 mm long basal stipe, densely puberulous, ca. 4 x 3 mm, the stipe merging into a puberulous annular disk 1 mm long and 3 mm wide. Fruit an orbicular capsule, with a well-developed 1-1.5 cm long basal stipe, 3.5-6 cm long (without stipe), 3-6 cm wide, ca. 1.5 cm thick, densely tannish stellate-tomentose, the surface verrucose from irregular short spine-like projections; seeds thin, suborbicular, to 3.5 cm in diam., the large round body completely surrounded by an hyaline-membranaceous wing.

Discussion
One of the most characteristic cerrado species, easily distinguished from Z. tuberculosa by its larger flowers and smaller fruits and stature.
