Its distribution extends into northern Baja California.

Description

This fern produces frilly leaves up to about 30 centimeters long, each divided into segments which are subdivided, the ultimate segments just a few millimeters long and widely lance-shaped to oblong. The leaf segments bear resin glands which exude a very sticky, clear fluid.

The leaves are also somewhat hairy. The leaf segments have curled edges along which are located the sori with their brown sporangia.
