Distribution: Peru and Bolivia. Known from three main areas: the Pacific slopes of the Cordillera Occidental of Peru in Lima and Ancash, near springs and in moist canyons, 2,800-3,500 m; on the eastern slopes of the Peruvian Andes from Huanuco to Cuzco, in cloud forest and moist upland shrub vegetation, 2,500-3,400 m; and on the northeastern slopes of the Bolivian Andes in Depts. La Paz and Cochabamba, in cloud forest, 2,200-3,100 m.
Habit: Erect to scandent shrubs 1.5-4 m tall or climbing in trees to 10 m above ground. Young growth subcanescent or occasionally pilosulous; branchlets terete, subdivaricate, green to wine red; older branches 5-20 mm thick with tan, exfoliating bark.
Leaves: Leaves 3-5-verticillate, mostly ternate or quatemate, rarelyopposite, firmly membranous, (narrowly) elliptic to oblanceolate, acute to narrowly cuneate at the base, acute to subacuminate at the apex, 4-17 cm long, 1.5-6.5 cm wide, dull to nitid dark green and glabrous above, pale green and subglabrous to strigose mostly along veins and margins below; secondary veins 7-17 on either side of the midvein, often reddish below; margin denticulate. Petioles glabrous to loosely strigose, (5-)8-20(-25) mm long. Stipules triangular, firm, often connate, 2-2.5 mm long, ca. 1.5 mm wide, deciduous.
Flowers: Flowers few to numerous, axillary and pendant, usually grouped toward branch tips, pedicels stout, smooth, 1-1.5 mm thick, 18-45 mm long, suberect in bud, drooping at anthesis, generally green, ovary narrowly oblong, terete, 10-13 mm long, 3-4.5 mm thick, generally glabrous, green, floral tube subcylindric, firm, walls 1-1.5 mm thick, smooth, (28-)36-47 mm long, (3-)4-8 mm wide at the base, sometimes very slightly narrowed above the nectary, straight or slightly widened above until (5-)6-12 mm wide at the rim, glabrous to puberulent outside, densely villous inside above the nectary for 7-10 mm, glabrous above, sepals lanceolate, acuminate, 17-26 mm long, 4-7 mm wide, forming a tapered point in bud, spreading to subdivergent at anthesis. Tube waxy light pink, lavender, or light red, sepals pink to light red with light green to whitish tips or margins, at times entirely whitish green, petals orange to scarlet,. usually drying purple streaked, lance-oblong to oblanceolate, obtuse to broadly acute at the apex, slightly undulate, 14-18 mm long, 4-6(-7) mm wide, suberect at anthesis. Nectary green, unlobed, 2.5-3 mm high, ca. 1.5 mm thick, filaments pink to light. red, 14-23 mm and 8-18 mm long, anthers oblong, 4-6 mm long, 2-3 mm wide', white, style stout, pink to light red, glabrous, stigma subclavate, subentire (very slightly 4-cleft at the apex), 3-4 mm long, 2-3.5 mm wide, dull white, exserted 2-12 mm beyond the anthers.
Fruit: Berry ellipsoid, 20-26 mm long, 10-12 mm thick, nitid green to red purple, smooth surfaced.
Seeds: Seeds tan, 1.8-2.2 mm long, ca. 1 mm wide.
Chromosomes: Gametic chromosome number n = 11.
