Description:
Species Description - Erect or rarely clambering shrub, (0.3-) 1-3(-5) m tall and to 7.5 cm diam.; mature stems terete, striate, glabrous or rarely puberulent, and also usually weakly strigose; bark reddish-brown to grayish, thin, often exfoliating in strips; twigs subterete often complanate or ribbed, puberulent and/or pubescent with white hairs, also with appressed to spreading, setose-hirsute, straight or crisped, ferruginous, base swollen, eglandular hairs to ca. 2 mm long (also with short, gland-tipped setae 0.2 mm long); buds ovate, 1-2.5 mm long, scales reddish-brown, short-pilose. Leaves usually ascending when young but with a strong tendency to be reflexed later along mature stems, blades broadly ovate (nearly rotund), elliptic to ovate, (0.5-)1.5-2.5(-3) × (0.2-)l-2 (-3.3) cm, base rounded and subcordate, or obtuse, apex acute to obtuse or short-acuminate (nearly rounded), margin crenate to serrate with each tooth terminating in a short-setose (gland-tipped) hair, lamina flat to slightly revolute adaxially, essentially glabrous but normally short-pilose only at base of midrib and onto petiole (short-pilose over entire surface then glabrate, also at very base along midrib possessing short, gland-tipped setae ca. 0.2 mm long), abaxially glabrous or more commonly sparingly short-strigose with basally swollen, eglandular hairs, sometimes also with scattered, short (ca. 0.2 mm long), gland-tipped setae; midrib, lateral, and reticulate veinlets plane and obscure to raised and conspicuous above, raised and conspicuous beneath; petiole subterete, broadly flattened, and canaliculate above, 1-2(-4) mm long, short-pilose above and also deciduously short-strigose beneath with setose hairs as on twigs (also with up to 0.2 mm long, black, clavate, gland-tipped setae in var. elassantha). Inflorescence with flowers solitary toward branch tips, in axils of usually reduced leaves, the leaves sometimes becoming nearly bract-like (i.e., 5 × 2 mm); pedicels subterete, slightly striate, (4-)5-8(-17) mm long at anthesis, elongating to 10-17 mm long in fruit, weakly to densely puberulent or short-pilose (or puberulence lacking) and also weakly to densely strigose with hairs short (ca. 0.3 mm long), straight, and gland-tipped, or longer (to 1.5 mm long) and then straight to crisped and eglandular, the indumentum in nearly any combination or with one or more types lacking; bracteoles 2-9 along basal half of pedicel, ovate to ovate-elliptic, 1.5-3.5 × 1.5-2.5 mm, acute, the lowest usually adaxially densely pilose becoming more glabrous distally (glabrous on lamina but always ciliate); floral bract similar to bracteoles but nearly always pilose. Flowers with calyx 3-5 mm long, lobes ovate, (1.8-) 3-3.5 × (1.7-)2-2.5 mm, acute to acuminate, glabrous to distally short-pilose without and distally sparsely to densely short-pilose within, ciliate to ciliolate and often also marginally glandular-fimbriate; corolla urceolate, cylindric-urceolate, to rotate-campanulate (basally gibbous), (4-)5-6.5 × (2.5-) 4-5(-7) mm, glabrous, weakly short-pilose, or moderately pilose without (scattered short-pilose within), white to pale yellowish-green, lobes ovate, to 1.6 mm long, obtuse; stamens (2.5-)3-4 mm long; filaments (1.6-)2.3-3.3 mm long, glabrous to densely pilose; anthers 0.7-1.3 mm long, awns conspicuous; ovary nearly glabrous to densely short-pilose; style (2-)3.5-4.8 mm long, glabrous to short-pilose proximally. Fruiting calyx globose when fresh but turbinate when dry, (5-)6-10 mm diam., blue-black.
