 Woolsey ; Summerville, Contra Costa Co., Apr. 16, 1889, Chesnut 

 & Drew; Antioch, Contra Costa Co., Davy, no. 874; same locality.

 California approach very near to the typical form and may be 

 classed with it : Bear Valley, Parish, no. 2013 ; Ballona, Los An- 

 geles Co., Braunton, no. 429 (very robust with large heads and 

 glandular inflorescence but passing through other forms gathered 

 in the same locality by Mr. Braunton into var. tenuifolia) ; near 

 Bardsdale, Ventura Co., Hall, no. 3238; Ojai Valley, Hubby, no. 

 86.

 obtuse elliptic-oblong paleae one-half as long as the corolla or

23, 1888, Chesnut & Drew; San Bernardino Co., ace. to Gray, 

 but there is no specimen in the Gray Herbarium from south of 

 Ventura Co., ace. to Parish. 474 J. P. Tracy has collected a form 

 in Napa Co. (no. 1571) having disk-achenes with 5 principal pap- 

 pus-paleae nearly as long as the corolla, and in addition an outer 

 series of 5 short ones.

 carpha curta Gray, Syn. Fl. i. pt. 2, 452 (1886) ; Hall, Bot. Gaz.
