Lactuca scariola L. Sp. PI. ed 2, 11 19. 

 The form of prickly lettuce heretofore reported from Cali- 

 fornia has been the variety integrata Gren. & Godr., distin- 

 guished by its spinulose-toothed leaves. The species, which has 

 runcinate or pinnately lobed leaves, is now abundantly estab- 

 lished about Urbita, a suburb of San Bernardino. 



Heltanthus petiolaris Nutt. Journ. Phila. Acad. 2: 115. 

 In Hall's Compositae of Southern California this species is 

 credited to our region on my authority, founded on a single col- 

 lection made at Fredalba Park. The specimen is no longer in 

 existence, and its authenticity is uncertain. But in recent years 

 the plant has become very common in alfalfa fields, in some 

 parts of San Bernardino valley, where it has perhaps been intro- 

 duced in the seed of barley, which is planted as a shade crop in 

 starting alfalfa. It is probably never native in our region.
