Buds globose, slightly inflated, the corolla strongly exserted form the calyx tube long before anthesis.
    Flowers all perfect, 5-merous. Buds globose, slightly inflated, the corolla strongly exserted form the calyx tube long before anthesis. Calyx tube ca. 0.5 mm, flattened and open, the lobes < 0.2 mm, mere apiculae from the entire rim, glabrous with tufts of tiny simple trichomes to 0.2 mm on the apiculae. Corolla 1.1-2.5 cm in diameter, violet or pale violet, stellate-rotate, lobed ½ to 2/3 of the way to the base, the lobes 5-9 x 3-4.5 mm, spreading or slightly cupped at anthesis, densely and minutely pubescent on the tips and margins, the trichomes simple, uniseriate, tangled. Filament tube minute, the free portion of the filaments markedly unequal, the longest filament 2-3 mm, elongating as anthesis progresses, the other four 1-1.5 mm, quite variable, occasionally two filaments longer, all glabrous; anthers 2-3 x 1-1.5 mm, occasionally one anther slightly larger, ellipsoid, loosely connivent, yellow, poricidal at the tips, the pores not markedly lengthening to slits with age. Ovary glabrous; style 7-10 mm, strongly curved away from the anther on the long filament, glabrous; stigma capitate, the surface minutely papillose.
    Fruit a globose berry, 0.8-1.4 cm in diameter, bright shiny red when ripe, glabrous, the pericarp thin; fruiting pedicels 0.8-1.4 cm, ca. 1 mm in diameter at base and apex, pendant from weight of berries, not markedly woody.
    Seeds 4-20 per berry, 4-4.5 x 2.5-3 mm, flattened-reniform, pale yellowish tan, the surfaces minutely pitted, the testal cells pentagonal, the lateral cell walls elongate to 0.5 mm, leaving a wing of ca. 0.5 mm around the seed and the seed appearing pubescent.

Leaves simple, compound or lobed, often all on the same plant, the lobes mostly ovate, the sinuses broadly rounded, apically long-acuminate, basally acute, obtuse, truncate or cordate; petioles 3-5 cm long. Inflorescence a large, showy, ternately- branching panicle, the peduncle slender; pedicels slender and abscissing nearly at the base; calyx 2-3 mm long, apically truncate or with very short deltoid or umbonate lobes, not splitting at the sinuses and not expanded in the lower portion; corolla purple, pinkish, blue or rarely white, 2-5 cm across, lobed to more than one half the way down; stamens subequal, the filaments glabrous, short, the anthers stout, 2.5-3.5 mm long, dehiscing by large terminal pores which may coalesce, and ultimately by longitudinal slits; ovary and style glabrous, the stigma small, capitate.
