Description:
Description: Terrestrial shrub from a single arching stem to 4 m tall; seedlings with stems flexuous, finely short white pilose, the leaves elliptic, finely short white pilose on both surfaces; mature branches conspicuously and persistently 5-winged (wings to 3 mm broad), smooth, glabrous, reddish-brown. Leaves elliptic to ovate-elliptic, (8-)11-20(-23) x (4-)7-16(-19) cm, basally cordate and clasping, apically rounded, glabrous; 5(-9)-plinerved from base, nerves red beneath when fresh, midrib and inner 1(-2) pairs of lateral nerves conspicuously impressed above and raised beneath, outer 1-2 pairs of lateral nerves inconspicuously and slightly impressed to plane above but raised beneath; veinlets inconspicuous on both surfaces; petioles subterete, ovoid, rugose, 4-5 mm long and 5 mm in diam., glabrous, red when fresh. Inflorescence paniculate, to 850-flowered; primary rachis and lateral branches subterete, glabrous, green when living, primary rachis to 53 cm long and 6 mm in diam., primary lateral branches 20-28 cm long, secondary lateral branches ca. 13 cm long; floral bracts caducous, cucullate, ovate, ca. 6 x 8-9 mm, basally clasping, apically rounded, glabrous, green tinged with red when fresh; pedicels terete, striate, glabrous, 6-7 mm long at anthesis (elongating to 11-12 mm in fruit), ca. 1 mm in diam. but swollen to 1.5 mm at base, green when fresh; bracteoles caducous, similar to the floral bracts but ca. 3 x 4 mm. Flowers: calyx glabrous, 4 mm long, green when fresh; hypanthium cylindric, ca. 1.5 mm long and 4 mm in diam., basally slightly apophysate; limb slightly spreading, ca. 2-2.5 mm long; lobes ovate to hemispheric, apiculate, ca. 0.75 mm long, connivent after anthesis, marginally lacerate-glandular; sinuses acute; corolla bottle-shaped, glabrous, 13-14 mm long and 7 mm in diam., purplish-green with the purple pigment restricted to inner (morphologically lower) epidermal surface, lobes triangular, acute, 1.5 mm long, flaring at anthesis, white; stamens 10-11 mm long; filaments very sparsely pilose along margins distally, alternately ca. 2 mm and 2.8-3 mm long; anthers subequal, 8.5-9 mm long; thecae ca. 3 mm long; style ca. 12 mm long. Berry ca. 13 mm in diam.
Distribution: Endemic to Colombia and known only from the type locality, where the plants were growing in constantly misty habitats along extremely steep disturbed roadside slopes through a cloud forest area, at 1890 m elevation.
Uses: This species, like C. divaricata, produces an abundance of large, sweet-tasting berries and with a little effort could become a locally important crop plant.
Conservation Status: Rare and endangered.
