Description:
Author : John Kress, Xavier Cornejo & Reinaldo Aguilar.
Description: Slender cannoid plants 1-3(-5) m tall; shoots monomorphic. Leaf sheaths glabrous; petioles poorly defined; blades ovate to elliptic, or narrowly so, (8-)11-34 x (2.4-)3.6-9.2 cm, glabrous on both sides, without wax or epidermal papillae, the base rounded to broadly cuneate. Peduncles obscure or up to ca. 4 cm long. Inflorescences distichous, 7-15 cm long, with 2-8 spathes, the spathe angle 20-85º, all spathes usually unappendaged; axis yellowish or orange, glabrous or rarely ± pilose; spathes 6.8-15 x 0.5-1/5.2-9.7 x 0.5-0.9/5-8.3 x 0.5-0.9 cm, orange shading into yellow or green distally, glabrous or rarely somewhat pilose; bracteoles 2.2-3.5(-4.7) cm long, glabrous or subglabrous; pedicels 0.9-2.3 cm, glabrous or sparsely pilose at base; ovary 4.7-8.5 x 3.2-4.7 mm, glabrous or subglabrous; perianth straight or slightly curved (uniformly or sigmoid), ± tubular with free sepal only slightly salient at anthesis, 54-72 mm long, yellowish to orange, typically without greenish tinge distally, glabrous or subglabrous to rarely ± arachnoid; staminode ± plane to markedly convex, narrowly oblong to ± linear, 8.1-17 mm long, the apex acuminate or apiculate; style smooth and glabrous. Fruits 9-12 x 6-9 mm. Pyrenes 7-11x 5-6 mm (Andersson, 1985).
Common names: Esuar gid (Kuna, Panama), platanillo (Spanish).
Distribution: Nicaragua to western Colombia from near sea level to ca. 1150 m (Andersson, 1985).
Ecology: In wet forests. It is often luxuriant in recent clearings, but is not competitive in open habitats (Andersson, 1985).
Phenology: This species has been observed with flowers throughout the year.
Pollination: The flowers are pollinated by hummingbirds (Kress, 2003).
Dispersal: The fruits are eaten by birds.
Taxonomic notes: Heliconia longiflora is characterized by long tubular flowers with oblong to linear staminodes, which are truncate to indistinctly apiculate at apex. This species comprises two subspecies, in our area the typical subspecies is found.
Conservation: Not recorded.
Uses: Occasionally cultivated as an ornamental.
Etymology: The epithet refers to the long perianth.
