Dry alkaline desert flats, 2800 to 3500 feet : southern Mohave Desert. East to

Note on range. — In California, Pliaeelia parishii is known only from desert playas at Rabbit 

 Springs in the southern Mohave Desert. Only one other station, Steptoe Valley in White Pine 

 Co., Nev., is known. It was collected there by M. E. Jones in 1891. It is thus, as to our knowledge, 

 the rarest of Californian Phaceliae.
