Inflorescence with flowers solitary in axils of upper leaves (in hybrids with G. erecta, short racemes with ca. 3 flowers mixed with solitary flowers on same branch);  pedicels subterete, 4-10 mm long, short-pilose with white hairs, also weakly to moderately hirsute with thin, straight to crisped, elgandular to minutely gland-tipped, ferruginous hairs;  bracteoles 3-10, scattered over length of pedicel, spreading, somewhat cochleariform, striate, ovate to obovate, 3-5 x 2-2.8 mm, acute, dorsally glabrous, ventrally glabrous to sparsely puberulent, ciliate;  floral bract indistinguishable from bracteoles.  Flowers with calyx 4-4.3 mm long, glabrous or very rarely puberulent, lobes broadly ovate, 2.5-3.5 x 2-2.8 mm, acuminate, ciliate, puberulent within;  corolla urceolate, terete, 5.5-7.8 x 5-6.5 mm, externally white short-pilose and also strigose with straight or crisped, eglandular to gland-tipped, ferruginous hairs, internally densely short-pilose, white to pinkish when fresh, lobes ovate, ca. 1 mm long, obtuse;  stamens 4.8-6 mm long;  filaments 3-5 mm long, densely short-pilose;  anther 2-2.5 mm long, awns conspicuous;  ovary densely short-pilose, sometimes canescent;  style to 6 mm long, short-pilose at base.  Fruiting calyx globose, 9-10 mm diam., glabrous, dark blue-black.

     Distribution (Map).  Endemic to Oaxaca, Mexico where it is locally common and occurring in open, disturbed sites sometimes forming thickets in Quercus-Pinus forest at elevations of 2500-2923 m.  Flowering Mar to Oct and fruiting Sep to Mar.

     Common names and uses.  Tzinutpe (Mije Indian, Oaxaca) and capulincillo del diablo (Spanish, Oaxaca) (cf. Schultes, 1941). The fruits are used as food by the Chinantee and Mije Indians in Oaxaca (Schultes, 1941).  Lawton 799 (NY) states that the flowers were visited by hummingbirds.
