Characteristics

Epiphytic or terrestrial, bushy shrubs 0.5-1.5(-2) m tall; branchlets sharply ridged and grooved, indistinctly 3-angled to irregularly 4-angled, glabrous, sparingly strigillose or minutely puberulent; mature branches becoming terete, grayish to blackish, conspicuously fissured; internodes V'/5-3% as long as the sur-rounding leaves. Leaf blades coriaceous, entire to obscurely and microscopically serrulate, broadly elliptic to somewhat obovate or spatulate, (0.8-)1.2-1.8 cm long, (4-)6-12 mm wide, apically obtuse to broadly rounded, basally cuneate, glabrous above, beneath evenly but sparingly beset with appressed, amber colored trichomes 0.2-0.3 mm long; midvein and the principal veins slightly elevated above to nearly plane, beneath the midvein and the 1-2 pairs of paralleling prin-cipal veins plane or slightly elevated, dark green above, pale green beneath; petioles 3-5 mm long, glabrous, flattened above. Inflorescence of solitary, axillary, subsessile flowers; pedicles disarticulating apically, 2-3 mm long; bracteoles subopposite, broadly clasping, semiorbicular, ciliate, 1.5-1.8 mm be-low the base of the calyx tube, ca. 1.5 mm long, 1.8-2.0 mm wide, scarcely overlapping the base of the hypanthium; bracts 1-3, deltoid to acutely oblong, situated near the base of the pedicel. Flowers with the hypanthium terete, short, cylindric, glabrous, ca. 3.5 mm long, 2.0-2.2 mm in diameter; calyx lobes 3, erect, broadly deltoid, acute, ca. 0.5 mm high, entire, eciliate, glabrous; corolla deep red, thinly fleshy, the tube cylindric, abruptly tapering into a basal por-tion 2.0-2.3 mm long, 1.0-1.4 mm in diameter, the longer portion of the tube 5.0-5.5 mm long, ca. 2.5 mm in diameter, trichomes few, ascendent, 0.1-0.2 mm long, the lobes 3, erect, 1.5-2.0 mm long, 1.0-1.2 mm wide, acute, oblong deltoid; stamens 6, ca. 1 mm shorter than the corolla tube, the free portion of the filaments ca. 2.5 mm long, flattened, glabrous, the anthers granular, 2.5-2.8 mm long, each theca tapering into a slender tubule 2.5-2.8 mm long, dehiscing by an introrse, elongate, oval slit ca. 1.5 mm long; style glabrous, slender, ex-tending 1.0-1.2 mm beyond the stamens or to the top of the corolla tube. Berry at first greenish white turning dark blue.
