The flowers are followed by long, green, hairy, tapering fruits with a single curved "horn" that splits in half when dry to form 2 long, sharp, wooden "claws". The leaves are green, hairy, sticky, entire to shallowly lobed, and rounded, triangular-ovate, or heart-shaped. The stems are plump, hairy, green to tan in color, and erect or spreading.
The similar Ram's Horn (Proboscidea louisianica) has flowers with rust-spotted upper lobes.
