26 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 13 



Spergularia macrotheca (Hornem.) Heynh., Nomen. 2:689. 

 1840. 



Santa Rosa Island, Becher Bay, August 2, Elmore 189. 



Saline soils near the coast from Washington to Baja California; 

 type from California. 



Papaveraceae 



Eschscholtzia californica Cham, var., in Nees Hor. Phys. Ber. 

 73. 1920. 



Santa Rosa, Becher Bay, August 2, Elmore 187, on dry hillsides. 



The material is not sufficient for certain identification. It may be the 

 same as the collection annotated by Hoffman (Bull. So. Calif. Acad. Sci. 

 31:102. 1932) as Eschscholtzia sp. He stated that it is an annual with 

 clear yellow flowers on Santa Cruz Island. On the basis of fruit and re- 

 ceptacle, however, I have no hesitancy in assigning it to the E. californica 

 complex, which is so well known for its variability. It differs from E. 

 californica mariti?na, the common variety of the islands, in the non- 

 glaucous and longer-lobed leaves, and the reduced stature. 



Eschscholtzia californica maritima Jep., Man. Fl. PI. Calif. 

 402. 1925. 



San Miguel Island, August 10, Elmore 329. Tyler Bight, August 3, 

 Elmore 320. Point Bennett, September 12, Elmore 337. 



Endemic to the Channel Islands where it is known from Santa Cruz, 

 Santa Rosa, and San Miguel, the latter island, according to Hoffman, 

 having the most widely dispersed population. 



Platystemon californicus Benth., Trans. Hort. Soc. Lond. II, 

 1:405. 1835. 



Santa Cruz Island, hill west of Prisoners Harbor, April 17, Elmore 

 458. 



Widely distributed in western United States; also in northern Baja 

 California. 



Cruciferae 



Lepidium lasiocarpum Nutt. in Torn & Gray, N. Am. Fl. 1 :115. 

 1838. 



San Clemente Island, February 18, 19, Elmore 401. 



Widely distributed in the southwestern United States and northern 

 Mexico; type from near Santa Barbara, California. It has been collected 

 on nearly all of the other Channel Islands. The above cited collection 

 consists of several depauperate specimens, 6-8 cm high, fruiting, and are 

 the first taken from San Clemente.
