SULPHUR FLOWER (Eridgonum umbellatum, Torr.). The 

 genus Eriogonum is one that we have to go to the Far West to 

 find at home, but there it is extremely abundant. Of the 

 140 species or so, fully hah* are indigenous to our Pacific 

 Coast, and the identification of the species in many cases is 

 work for the patient special student. The flowers, numerous 

 but small, are six-parted, colored in the different species 

 white, pink, or yellow, and when faded still cling to the achene. 

 Stamens 9, styles 3. 



Of the few species that have attained popularity enough to 

 acquire a common name, the Sulphur Flower is deserving of 

 especial mention. The umbeled heads of fragrant, sulphur- 

 yellow flowers terminate a reddish stem about a foot tall, 

 that rises from a rosette of grayish green leaves white-woolly 

 beneath. It is rather variable in its characters and botanists 

 have proposed a number of varieties. In summer its cheerful 

 colonies often cover large areas on dry, open mountain slopes 

 of the Sierra Nevada and Coast Ranges, at an elevation of 

 from 4,000 to 9,000 feet in California, north to Washington and 

 eastward to the Rocky Mountains,
