Erect shrub (0.2-)1-3 m to small tree 10
m tall x 15 cm dbh; mature stems terete, striate, hispid with basally
swollen, elgandular, straight to ± crisped hairs to 2.5 mm long;
bark grayish- or reddish-brown, cracking longitudinally; twigs terete to
subterete, striate, commonly white puberulent (or not) and also strigose
or more often densely hispid as stems; buds ovate, complanate, scales
2, ciliate, otherwise glabrous. Leaves spreading, perpendicular to
stems or often completely reflexed, elliptic, ovate, or somewhat obovate,
smooth or wrinkled when dry, (0.5-)0.8-1.0(-1.5) x (0.3-)0.4-0.7(-1) cm,
base rounded or broadly cuneate-attenuate, apex acute and obtusely callose-apiculate,
margin obscurely serrate, revolute over entire length causing leaves to
be concave (strongly revolute, or flat), basically glabrous above or puberulent
at base along midvein, strigose or rarely glabrous beneath with basally
swollen hairs to 2 mm long; midrib plane to slightly raised or slightly
impressed above, raised and conspicuously thickened at base beneath, lateral
nerves (2-3 per side) plane to slightly raised or impressed above and slightly
raised beneath, reticulate veinlets slightly raised but inconspicuous on
both surfaces; petiole subterete, flattened above, 1-2 mm long, puberulent
above and usually hispid beneath. Inflorescence with flowers solitary
in the axils of normal or slightly reduced leaves and then congested at
tips of new growth; pedicels terete, striate, (4-)6-10 mm long, longer
than subtending leaves, puberulent (sometimes not) and also hirsute with
straight to crisped, eglandular hairs to 1 mm long (also mixed with short,
glandular-setose hairs ca. 0.2 mm long); bracteoles 2-3, basal or
with one midway along pedicel, broadly ovate, 2-3 x ca. 2 mm long, acute,
ciliate (also sparsely hirsute or glandular-fimbriate); floral bract
similar to bracteoles. Flowers with calyx (3-)3.5-4.5 mm long, lobes
ovate or triangular, 2.2-2.6 x 1.5-2 mm, acute to short-acuminate, ciliate
otherwise glabrous without (sparsely short-pilose or short-strigose), but
short-pilose within; corolla cylindric-urceolate, rarely appearing
campanulate when dry, (3-)5-6 x 3-3.5(-6) mm, glabrous within and without,
white when fresh, lobes oblong, obtuse; stamens 2.5-3 mm long;
filaments 1.5-2.2 mm long, glabrous; anthers 1-1.4 mm long, conspicuously
awned; ovary densely short-pilose with somewhat cinereous hairs;
style 2-4 mm long, glabrous or basally short-pilose. Fruiting calyx
globose when fresh but often turbinate when dry, 6-8 mm diam., glabrous,
white to white flushed with pink, or turning blue-black.
Distribution (Map). Widespread in wet montane forest, páramo, moist roadside slopes, and subpáramo thickets of Colombia and Ecuador, rare in Peru at elevations of (2000-)2400-3500(-3800) m. Flowering and fruiting throughout the year.
