Perityle inyoensis, known by the common names Inyo rockdaisy and Inyo laphamia, is a rare species of flowering plant in the aster family.[2][3]

It is endemic to Inyo County in eastern California.

It is known from just 10 populations in the southern Inyo Mountains, at elevations of 1,800–2,710 metres (5,910–8,890 ft).[4] Its habitat is dry, rocky mountain slopes, often in limestone.[2]

Description

The inflorescence bears one to three flower heads each under a centimeter wide. The head has yellow disc florets and no ray florets.[2] The fruit is a fuzzy achene about 3 millimeters long.[2][3]
