The typiciil fonii, which liuiges I'loiu Witshiiigton Tonitoiy and Oregon to New Mexico and 

 aooss the continent, is niiely found in California. Tlie variety truncata is fre([iient I'roni San 

 Benito County nortlnvard to Washington Territory, and in the Sierra Nevada. The variety linea-

 tains. It is scarcely more than a western form of the species, as both broad and linear leaves 

 are often found ujion the same plant. The sjiecies is popularly known as fcavinc.
