Inflorescence spreading-pendent, peduncle 35-65 cm long, spathe oblong-lanceolate, pale green turning purplish, 8.5-27 cm long, 1.5-5 cm wide; stipe to 2.5 cm long, sometimes arching; spadix green turning purplish, 5-26 cm long, sometimes arched at base, 8-16 mm diam. at base; berries orange; seeds 1-2. See Croat (1983: 279) for a more complete description.

The species ranges from Costa Rica to Panama at elevations of 2,000 to 3,000 m in lower montane rain forest, growing at higher elevations than any other Anthurium in Costa Rica or Panama.

Anthurium concinnatum is in section Belolonchium and is recognized by its large, subcoriaceous, cordate blade, its curved stipe, its persistent, exserted stamens, and its high altitudinal range. The species usually has long stems that, although rooted in the soil, usually lean on trees for support.
