Description:
Author : John Kress, Xavier Cornejo & Reinaldo Aguilar.
Description: Musoid plant 2 m tall; pseudostem yellow-green, 90-125 cm tall. Leafy shoots solitary or in pairs; petioles 34-45 cm long, glabrous; blades oblanceolate, to 103 x 25 cm, glabrous on both sides. Peduncles red with green striations, 14-17 cm long, puberulous. Inflorescences pendulous, spiral, to 45 cm long, bearing 8-10 spathes per inflorescence, the spathe angle 120-165ยบ, becoming more reflexed with age; axis flexuose, pink-red, puberulous to tomentose; spathes pink becoming green toward apex, 19-22 x 7-8 cm, puberulous; floral bracts translucent, pale yellow, stiff, 3.5-4.2 cm long, persistent, puberulous abaxially; pedicels pale yellow, 1-1.2 cm long, puberulous to tomentose. Flowers 15-20 per spathe; ovary pale yellow, 4-6 x 6-7 mm, puberulous to tomentose; perianth yellow, 51-55 mm long, densely puberulous; free sepal reflexed, the fused sepals with apices sometimes slightly reflexed; staminode white, 10-11 x 2-3 mm; stamens with anthers flared ouside perianth apex. Fruits sparsely tomentose.
Common names: Platanilla, platanillo (Spanish).
Distribution: Costa Rica and Panama from 100 to 1500 m.
Ecology: In moist and wet forests.
Phenology: This species has been observed with flowers mainly from Jan to Sep (Kress, 1984).
Pollination: The flowers are pollinated by hummingbirds (Kress, 2003).
Dispersal: The fruits are eaten by birds.
Taxonomic notes: This species is a member of the trichocarpa group. Slightly pubescent, bright pink spathes with green apices, a puberulous perianth, and stiff, conspicuous floral bracts distinguish Heliconia colgantea from its closest relative, H. trichocarpa Daniels & Stiles (Kress, 1984).
Conservation: Not recorded.
Uses: Occasionally cultivated as an ornamental.
Etymology: The epithet probably refers to the pendulous inflorescences.
