auriculate

Most Paleo Indian types, including fluted points, are auriculate.

The auriculate hafting area is usually expanded-rounded with an incurvate basal edge.

The auriculate hafting area is usually contracted rounded, but may be parallel rounded or expanded rounded.

Leaves crowded at the ends of the flowering branches, obovate or spatulate, auriculate at base, smooth (1 ft. long).

When a simple leaf is divided at the base into two leaf-like appendages, it is called auriculate.
