HTDROPHYLLACEAE 



Bushes crown-sprout freely after chaparral fires. There is also free reproduction by seed, 

 especially on "burns" where seedlings may make extremely dense stands. The leaves of seedlings 

 are oblong-ovate and broader than the adult leaves. Where seedings are well spaced on fertile 

 "burns," the blades of leaves may become remarkably large: 10 to 12 inches long and 314 to 4% 

 inches wide (cf. Columbia, Tuolunme Co., Jepson C446). Earely the leaves on fertile shoots may 

 be broadly oblong and 5 to 6 inches long. The species has marked vitality, is aggressive in its 

 territory and is one of the first of chaparral species to reoccupy cleared or pastured lands. 



In the California Black Oak belt of the Sierra Nevada between Mariposa and the San Joaquin 

 Eiver, Eriodictyon californicum is frequent and sometimes forms extensive colonies. It seems in 

 this part of the range largely to replace Adenostoma fasciculatum. Eriodictyon californicum may 

 also occur on the floors of montane valleys as in Indian Valley, northeastern Lake Co. 



The lobes of the corolla are a little revolute at the sides. 

 The pubescent ovary is seated on a deep-yellow disk. The 

 adnate portion of the filaments is narrowly 2-wuiged. 



In the Tulare County foothills the dried leaf is smoked 

 by settlers or mixed with smoking tobacco ; it is also chewed 

 separately. Sometimes one finds colonies of shrulis whose 

 leaves are heavily blackened by a sooty mold (conidial 

 fungus).
