This species is notable by having large pedatisect leaves, with sinuate margins and for its huge pendant inflorescence. This Anthurium has the largest leaves in comparison with the rest of the Central American species ( Croat 1983 ). They can be confused with sympatric A. pentaphyllum var. bombacifolium (Schott) Madison and A. kunthii Poepp. , but both differ by having slender stems, smaller leaves with entire or subauriculate lobes (never markedly sinuate).

Anthurium clavigerum represents a species of wide distribution. On Cerro Pirre, it grows along the lowland semideciduous forest and in mid-elevation evergreen forests, between 90 and 800 m . It is very common to observe adult individuals on trees associated with the banks of rivers and streams.
