Distribution, systematics and endangerment
Nolina interrata is very rare. It is common in the US state of California and in Mexico in Baja California at altitudes of 200 to 700 m. It grows in grassland on sandy to stony soil on flat hills and is associated with Yucca whipplei and various species of cacti.
Nolina interrata is a representative of the Arborescentes section and is currently little known. It is closely related to Nolina cismontana , but this one has a longer, more imposing inflorescence and green leaves . The species is fire resistant.
