Description

Ophioglossum californicum is a small, fleshy perennial plant growing from a caudex no more than 1.5 centimeters wide.

It produces one leaf per year. The leaf is divided into a thick, green blade-shaped part, which is sterile, and a fertile stalk lined with two rows of sporangia, the reproductive parts.
