Description:
Description: Erect to spreading evergreen shrubs to small trees to 1-10 m tall; bark peeling or flaking, reddish-brown to brown or gray; young twigs glabrous and usually glaucous, or tomentulose to tomentose, often red or reddish-purple. Leaves coriaceous, lanceolate to elliptic or oblong-elliptic, plane or slightly revolute, (1.4-)3.7-15.3 x (0.2-)1.1-5.4 cm, basally tapering to cuneate, apically acute, marginally serrulate to serrate or serrate-dentate, rarely subentire, upper surface glabrous, green and shining, or with slight pubescence and somewhat dull, lower surface glabrous, often very glaucous, or tomentulose to ferruginously tomentose; petioles 6-19 mm long, glabrous and often glaucous, or tomentulose to tomentose, often red or reddish-purple. Inflorescences racemose, the racemes clustered, or paniculate, to 3.5-15 cm long, glabrous or tomentulose to tomentose or glancular hirsute, trichomes glandular or not; floral bracts lanceolate to ovate, navicular to carubate, acuminate, (1.3-)2.5-8.2(-14) x 1.9-3.3 mm, often ciliate; pedicels 2.5-13 mm long; bracteoles basal to medial, acicular to lanceolate, (1.1-) 1.6-3.7 mm long, often ciliate. Flowers: calyx lobes triangular or ovate-triangular, (1-)1.4-3.1 x 1-2.2 mm, acute to acuminate, glabrous or pubescent, trichomes glandular or not, often ciliate; corolla cream or white or pink, (4.5-)4.9-8.6 x (3.7-)4.9-6.9 mm, glabrous or with hyaline trichomes, the lobes 0.9-1.7 x (1.4-)1.7-2.3 mm; stamens 2.5-3.7 mm long; filaments 2.3-3.3 mm long, villous; anthers 1-1.8 x 0.7-1 mm, the spurs 0.3-0.8 mm long; ovary glabrous; style 2.4-3.7 mm long, glabrous. Fruit (5-) 6-8 mm in diam., red when immature, dark purple to black at maturity; seeds 1.9-2.6 x 1.2-1.4 mm, surface reticulate.
Distribution: Central Mexico, from Jalisco east to Hidalgo and Veracruz, and south through the mountains of Oaxaca and the central highlands of Chiapas into E Guatemala, in open or disturbed areas or in the understory of mesic montane forests, at 1850-3300 (-3900) m. Flowering and fruiting throughout the year.
Cultivated: E (which subspecies is unknown).
