Description:
Description: Terrestrial, multi-trunked, erect shrubs to 2.5 m tall; capable of sprouting after fire damage; bark shredding, dark gray to nearly black; young twigs ferruginously tomuntulose, the trichomes eglandular, a few individuals with small scattered glandular trichomes, bark on young twigs shedding, orangish underneath. Leaves clustered near the stem tips, fewer present on the lower branches, coriaceous, narrowly lanceolate to broadly elliptic, to 17.7 x to 5.3 cm, apically acute, basally cuneate to tapering, marginally serrulate, plane or very slightly revolute, upper surface glabrous or sparsely tomentulose when young, lower surface ferruginously tomentulose, sometimes densely so, becoming less so with age, very young leaves sometimes with canescent tomentum; petioles to 15 mm long, indumentum as on young twigs. Inflorescences paniculate, to 17 cm long, sometimes with reddish coloration; rachis, pedicels, bracts, bracteoles, and cayxy lobes glandular hirtellous, the trichomes stalked, swollen-headed and glandular, to ca. 1 mm long; floral bracts glandular ciliate, bracteoles glandular ciliate. Flowers: calyx lobes triangular, to ca. 2 x 1.3-1.5 mm, glandular ciliate, green to pink or red; corollas 4.5-6 x ca. 3 mm, externally sparsely pubescent by eglandular hyaline trichomes, yellow-cream to white or light green, sometimes tinged with pink or red while in bud. Fruit red when immature, black at maturity.
Distribution: Endemic to Mexico, in the Sierra de Manantlán in SW Jalisco, in Pinus-Quercus-Abies forests, summit forests, thickets, and steep slopes, and is frequently found in areas of recurrent fire, at elevations of 2500-3000 m. Flowering Jan-Jul; fruiting Jan -Apr.
Illustration: Diggs (1995), figs. 8 and 9.
Type: Mexico. Jalisco: Mun. Cuautitlán, near crest of Sierra de Manantlán at Las Capillas, 25 km by road SE of Rancho Las Joyas, 2800-2850 m, 1-2 Jun 1986 (fl), Diggs et al. 3767 (holotype, MEXU; isotypes, BM, CR, DAV, DEK, DUKE, ENCB, F, G, GH, IBUG, ISC, K, Laboratorio Natural Las Joyas, M, MO, NY, SMU, TEX, US, WILLI, WIS (pop. sample of 15 indivs.), XAL).
