Myriopteris newberryi, formerly Cheilanthes newberryi,[1] is a species of lip fern known by the common name Newberry's lip fern. It is native to southern California and Baja California.

Description

Myriopteris newberryi has leaves up to about 30 centimeters long which are coated in matted white, gray, or brownish hairs. Each leaf is made up of subdivided segments where the ultimate segment is oval in shape, mostly flat, and hard to visualize due to its thick coat of hairs. On the underside are scattered sori containing sporangia. Each sporangium may have either 64 or 32 spores.[2]

Range and Habitat

In Mexico, Myriopteris newberryi is found in extreme northwestern Baja California from Tecate south to Punta Colonet, and also on the Pacific island of Guadalupe, off the shore of Baja California. In California it is found mostly in the coastal mountains from the San Bernardino Mountains and south, and on San Clemente Island just offshore. It grows in rocky places in mostly dry habitat such as the California chaparral and woodlands.[3]

Taxonomy

Based on plastid DNA sequence analysis, Myriopteris newberryi is a nearly basal member of Myriopteris clade C (covillei clade) and is relatively distantly related to other Myriopteris species.[4]
