Leaf blades ovate, 2-6(-9) × 1.7-5(-6.7) cm, ± flat, thick-coriaceous, ca. 0.4-0.7 mm thick; base cordate to less commonly rounded (to cuneate in immature plants); apex slightly acuminate or acute, to truncate or rounded; margin revolute or plane, apical portion irregularly sinuous to obscurely toothed, basal portion sinuous to entire; venation brochidodromous, 3° veins reticulate to percurrent; adaxial surface often roughened by thickened scale bases, especially near margin or toward apex, lepidote but scales usually quickly deciduous, glabrous on midvein, the veins usually slightly depressed, ± obscure above 4°; abaxial surface moderately to densely lepidote, otherwise densely pubescent, all veins prominently raised and forming conspicuous network; scales rust colored, deciduous to persistent, ca. 0.07-0.22 mm in diameter, erose to nearly entire; petiole 4-10 mm long, lepidote, otherwise glabrous; flower buds ± intermixed with vegetative buds. Inflorescences fasciculate to shortly racemose, 4-13-flowered; pedicels clearly articulated with calyx, stout, 5-20 mm long, lepidote, otherwise pubescent; bracteoles opposite to subopposite, basal or nearly so, narrowly triangular, 2-6 nun long; floral bracts 4-9 mm long, usually caducous. Flowers (5-)6-7(-8)-merous; calyx lobes triangular, with acuminate apices, (2-)2.5-6 × 1.5-5 mm, adaxial side slightly pubescent, especially at margins and near apex, abaxial side densely lepidote, otherwise moderately to densely pubescent; corolla carnose, urceolate, white to pink tinged, especially near mouth, 8-13 × 8-13 mm, abaxially densely to moderately lepidote; filaments roughened, 4.5-7 mm long, unappendaged or with spurs to ca. 0.6 mm long near junction with anthers; anthers 2-4 mm long; ovary lepidote, otherwise pubescent, placentae subapical to nearly central.
