Anthurium acutifolium is a member of sect. Pachyneurium and is distinguished by being a terrestrial plant (rarely epiphytic) with thin, oblanceolate to broadly lanceolate leaf blades that are attenuate at the base. It is similar vegetatively to A. consobrinum but does not have the arty emergent pistils characteristic of that species.
