The species is native to Ecuador (Cotopaxi, Los Rios and Pichicha) where it usually grows as epiphyte on the trees of the humid forests between the 150 and the 2100 m of altitude.
The genus is honoured to the merchant, botanical passionate and patron of the XIX century, John Maclean of Lima; the specific name is the combination of the Greek numeral adjective “πέντε” (pente) = five and of the substantive “πτέρυξ” (pteryx) = wing, wuth reference to the winged calyx.
Common names: tropical blueberry (English); gualicón, hualicón (Ecuador).The Macleania pentaptera Hoerold (1909) is a ramified epiphytic or terrestrial shrub with 0,6-2,5 m long stems and alternate leaves, simple, subsessile, oblong-ovate with cordate base often amplexicaul, obtuse apex, entire margin and veins sunken above and prominent below, of glossy dark green colour, coriaceous, 7-12 cm long and 2,2-6 cm broad.
Axillar and terminal inflorescences usually drooping, up to 4 cm long rachis, with 2-8 fleshy flowers, waxy, of orange red colour with green apex, rich of nectar. Obconical calyx, 0,8-1 cm long and of about 0,6 cm of diameter, truncated apex with five acute tiny teeth and five fleshy wings, up to 0,3 cm broad and beyond the apex 0,3-0,6 cm, persistent and enlarged when in fruit. Tubulose corolla, urceolate (enlarged at the base and narrower towards the apex), pentagonal, 1,7-2,2 cm long and 0,4-0,7 cm broad, with 5 triangular lobes with acuteapex, about 2 mm long, with white pubescent fauces, and 10 stamina. The flowers are pollinated by the hummingbirds. The fruits are whitish translucent globose berries, of about 2 cm of diameter, with a pleasantly sweet taste and rich of antioxidants.It reproduces by seed, in draining and aerated loam rich of organic substance maintained humid at the temperature of 24-28 °C, and by cutting.
Species rare in cultivation, but of extremely high ornamental potential, requires high luminosity, but not direct sun, intermediate temperatures, 16-30 °C, and high humidity, 60-80 %. It can be easily cultivated in pot with particularly draining loam, rich of humus, with addition of siliceous sand or agriperlite per a 30 %, maintained constantly humid, but without stagnations.
