Macleania pentaptera, also known as gualicón or hualicón,[2][3][4] is a species of tropical plant[3] endemic to Ecuador.[5]

Description

Vegetative characteristics

Macleania pentaptera is an epiphytic or terrestrial, branched shrub[3] with up to 3 m long branches.[4] The terete, glabrous branches have smooth, brown bark. The internodes are 2–3 cm long.[1] The glabrous, coriaceous,[1] ovate to elliptic leaves[4] with an entire margin[1] are (3–)7–14.5 cm long, and (2–)3.5–9 cm wide.[4] The pinnate leaf venation is impressed above, and is prominent on the abaxial leaf surface.[1] The glabrous petiole is 2–6 mm long.[4]

Generative characteristics

The axillary[4][1] or terminal,[1][3] racemose inflorescence with an up to 4 cm long rhachis[1] bears 2–7[4](–8) fleshy, waxy, nectariferous,[3] pedicellate,[4] tubular, vibrant, orange-red, green-tipped flowers[6] with 9–25(–33) mm long pedicels.[4] The five-winged, obconical,[1] 0.8–1 cm long, and 0.6 cm wide calyx[3] has five acute teeth.[1] The tubular, fused,[6] urceolate, pentagonal corolla[3] is 1.7 cm long, and 0.4–0.5 cm wide.[1] The throat is densely pilose.[4] The androecium consists of 10 stamens,[3][1] which are 10–12.5 mm long.[4] The gynoecium consists of 5 carpels.[1] The translucent, white[6] to green, globose, 20 mm wide berry[4] bears numerous seeds.[7]

Taxonomy

It was published by Rudolf Hoerold in 1909.[1] The variety Macleania pentaptera var. longicalyx published by Alexander Gilli in 1983 is not accepted and is widely regarded as a synonym of Macleania pentaptera.[3][8][4][5] Within the subfamily Vaccinioideae, it is placed in the tribe Vaccinieae.[9]

Etymology

The specific epithet pentaptera from the Greek pente meaning five, and pteryx meaning wing, refers to the five-winged calyx.[3][10]

Homonyms

The correct name of the homonym Macleania pentaptera published by Hermann Otto Sleumer in 1936[11] is Macleania ericae published by Hermann Otto Sleumer in 1938.[12]

Distribution and habitat

It occurs in montane forests of Ecuador[6] at elevations of 150–2100(–4000) m above sea level.[4]

Ecology

Pollination

The flowers are pollinated by hummingbirds.[3][6][13]

Herbivory

The leaves are gathered by Atta leaf-cutter ants.[14]

Use

It is sometimes cultivated as an ornamental plant,[13] but it is rare in cultivation.[13][6][10] The very sweet and pleasant fruit[2] is edible.[6][4]
