1907] Hall. Compositae of Southern California. 115 



Plant 1.5 to 6 dm. high from an annual or biennial root, stems 

 either several and erect from a decumbent base or single and 

 wholly erect, terminating in a large close glomerule or branching 

 above into a more or less open panicle (this less than 1.5 dm. 

 long) the branches of which are terminated by close glomerules : 

 leaves narrowly spatulate (the larger ones 3 to 6 cm. long, 4 to 12 

 mm. broad) or the uppermost ones linear or lanceolate, the short- 

 decurrent base rather broad and somewhat auricle-like : involucre 

 roundish, 5 or 6 mm. high and broa*d, the bracts with a greenish- 

 yellow tinge. 



Common on sandhills near the coast (San Diego, Santa 

 Monica, etc.) ; plentiful in moist places toward the foothills 

 (Witch Creek, San Bernardino, Pasadena, Ojai, etc.) ; less com- 

 mon in the Transition Zone of our mountains (San Jacinto Mts., 

 at 1600 m. alt.), and on the desert (Palm Springs, Calexico) ; 

 north to Oregon, east to Texas and Mexico. 



Var. confertifolium, Greene, Fl. Fr. 400 (1897). A stout 

 and low form with linear leaves densely clothing the stem up to 

 the mostly sessile dense cluster of heads. Near Los Angeles, 

 Braunton, nos. 237, 628; Mt. Pinos, Hall, no. 6591; and north- 

 ward with the species. 



G. WRIGHTII Gray has been reported from Ojai, Ventura Co., 

 by Miss Eastwood, 23 but I am unable to find specimens of this 

 species from west of Arizona. It is related to G. micro ceplialum, 

 but the spatulate or lanceolate leaves are not at all decurrent. 



ANAPHALIS MARGARITACEA (L.) B. & H. has been reported 

 from Santa Catalina Island by Mr. Brandegee, 24 but his speci- 

 mens cannot now be found. Since it is not otherwise known 

 from south of the Sierra Nevadas of Kern Co., an error in the 

 determination is suspected. This suspicion is strengthened by the 

 fact that other botanists have distributed Gnaphalium bicolor 

 from this island under the name of Anaphalis margaritacea, 

 which may be distinguished from all species of Gnaphalium by 

 the dioecious flowers.
