A warty leaf.
A warty excrescence.
Toads are not slimy or warty and do not jump like frogs.
In the African wart-hogs (Phacochoerus), which take their name from the large warty lobes projecting from each side of the face, the teeth are remarkably modified.
The skin of the upper surface is granular, with many irregular bony tubercles which give it an ugly warty look.
