A brief description of this island plant seems desirable 

 owing to the great variability of this species. 



75. Hemizonia Streetsii Gi-ay, Proc. Am. Acad., Vol. 

 XII, p. 162. "San Benito Island, Baja California." 



Reported also from San Clemente, Santa Catalina, and 

 Anacapa. On San Nicolas it was found on sea cliffs in 

 only one place. These specimens have a more compact 

 form than those from the other islands. This may be due 

 to immaturity. 



76. Leptosyne gigantea Kellogg, Proc. Cal. Acad. Sci., 

 Vol. IV, p. 198. "Near Cuyler Harbor, San Miguel 

 Island." 



It is also found on the following islands: Santa Barbara, 

 Santa Rosa, Santa Cruz, Santa Catalina, and Guadalupe. 

 On the mainland, Mrs. Blochman discovered it at Pt. Sal 

 and Mr. W. G. Wright obtained fine specimens from the 

 coast of Ventura County. 



When the stem is broken it exhales a strong odor of tur- 

 pentine which, around Pt. Sal, has given it the name 

 "Turpentine weed." 



Mrs. Trask reports this as growing in four or five local- 

 ities. About three plants were seen with eradiate heads, 

 growing amid the ordinary plants with radiate heads. 

 These eradiate heads are sterile and in the specimens 

 examined appeared to be composed entirely of bracts, form- 

 ing a globular head. 



Mrs. Trask note^ the leaflets of the San Nicolas plant to 

 be fleshy and filiform, those on the Santa Catalina plant 

 are not fleshy. 



Franseria Chaniissonis and F. bifinnatijida are two spe- 

 cies inhabiting the sand hillocks along the coast and are almost 

 always found associated together. They are most puzzling 

 to the systematist who endeavors to make boundary lines, 

 because they not only appear to run into each other but 

 each is variable even in regard to what are supposed to be 

 its own individual characteristics. Especially is this true 

 as regards foliage, pubescence, and size of the heads.
