Anthurium clavigerum is found from Nicaragua to the Guineas, Brazil, and Bolivia. In Costa Rica it occurs in premontane wet forest and tropical wet forest life zones at sea level to 700 m. In Panama, the species also occurs in premontane moist forest and tropical moist forest. It has also been collected at a reportedly 1,000 m elevation in what is apparently lower montane wet forest or lower montane rain forest.
This species is not confused with any other in Central America and can be recognized by its pedalisect leaves with sinuate to lobed margins and by its huge pendent inflorescence. The species may have leaf blades to about 2 m broad making it the largest species of Anthurium in Central America. It is a member of section Dactylophyllium and is most closely related to A. sinuatum Benth. ex Schott of South America.
