Description:
Species Description - Erect shrub 0.2-1.5 m tall with stems, twigs, leaves, and petioles usually glaucous; mature stems terete, striate, glabrous, sometimes ± nitid; bark reddish-gray, cracking and then exfoliating in thin, narrow strips; twigs subterete, bluntly angled, striate, glabrous or white puberulent, sometimes when puberulent also moderately to densely hirsute with thin, straight or crisped, eglandular or minutely glandtipped hairs 0.5-1 mm long, these sometimes deciduous and then leaving punctae; buds small, scales ovate, striate, maroonish, glabrous or weakly puberulent, ciliolate. Leaves subcoriaceous, ovate, ovateoblong, or elliptic-oblong, (2-)3-5.5(-6.8) × (1.1-) 1.7-2.5(—3) cm, base rounded, truncate or shallowly cordate, apex acute to shortly and sometimes abruptly acuminate, margin thinner than lamina, weakly serrulate to somewhat serrulate-crenulate, with each tooth terminating in a deciduous, short, gland-tipped hair (or subentire), glabrous or weakly puberulent above and also sometimes with scattered, crisped, eglandular, ferruginous hairs, beneath glabrate with punctae or weakly to densely hirsute with tiny, crisped, eglandular or gland-tipped ferruginous hairs, (these ± persistent); midrib impressed or slightly raised distally above and raised beneath, lateral nerves 4-7 per side, weakly impressed or weakly but conspicuously raised above and raised beneath, reticulate veinlets weakly impressed to weakly but conspicuously raised above and raised beneath; petiole subterete, broadly canaliculate above, rugose, 2-5 mm long, glabrous or pubescent as twigs. Inflorescence racemose, (3-)9-21 -flowered, one collection showing a solitary-flowered inflorescence along with racemes; rachis complanate, bluntly angled, 2-7 cm long, glabrous or puberulent and/or then sometimes also hirsute with short-stalked glands or thin, straight to crisped, eglandular or minutely gland-tipped, ferruginous hairs, sometimes glaucous; pedicels subterete, bluntly angled, 3-10 mm long and after anthesis elongating to 18 mm, glabrous or puberulent as rachis; bracteoles subopposite, located near base of pedicel, linear-ovate, 3-5 × 1-3 mm, acuminate to acute, glabrous or puberulent, ciliolate and marginally bearing minutely gland-tipped hairs; floral bract subcoriaceous, cochleariform, striate, ovate to oblanceolate, (4-)6- 11 × 3-4 mm, acute to acuminate, glabrous or puberulent, ciliolate, sometimes also with scattered, tiny, gland-tipped, ferruginous hairs dorsally. Calyx 4-6 mm long, sometimes very deeply lobed, glabrous or puberulent, sometimes also weakly to densely glandular pubescent with straight or crisped, ferruginous hairs, lobes smooth or striate, narrowly triangular to ovate, 2.5-4.5 × 1.6-2.2 mm, acuminate; corolla (4.5-)6-7.5 × ca. 6 mm, whitish-rose when fresh, glabrous or puberulent, also sometimes densely strigose with crisped, eglandular or glandular, white to ferruginous hairs, lobes ovate-triangular, ca. 1 mm long, obtuse; stamens 3.2-4.5 mm long (but few available to measure); filaments 2-2.6 mm long, glabrous or puberulent; anthers 1.6-2.5 mm long, the awns conspicuous; ovary glabrous or pilose; style 4-5 mm long, glabrous or short-pilose at base. Fruiting calyx 8-9 mm diam., glabrous or weakly hirsute with gland-tipped hairs, reddish- to blue-black.
