The species is found in Costa Rica and possibly also in Colombia and Ecuador at elevations of 2,000 to 3,000 m in lower montane rain forest. The species grows at higher elevations than any other Anthurium in Costa Rica or Panama. Anthurium concinnatum is a member of section Belolonchium and is recognized by its large, subcoriaceous, cordate blade and its curved stipe, its persistent, exserted stamens and high altitu-dinal range. The species usually has long stems that, although sometimes rooted in the soil, are usually leaning on trees for support.
