This species is reported from Farewell Gap, Tulare County 

 (10,500 feet), Hitchcock 3393 (Jepson, Fl. Calif., vol. 1, p. 107. 

 1912). It appears to be a part of 8. viridida Thurb., Bot. Calif., vol. 2, 

 p. 288. 1880. Professor Hitchcock (Jepson, I.e.) suggests that this 

 species is probably also native in Mexico.
