terminal clusters; leaves large at the base of the stem, two to 

 three and a half inches long, bi- or tri-pinnatifid, rachis and

 connivent before and after flowering, tube mainly hyaline, ribs 

 often blue or purple instead of green; corolla deep blue through-

San Francisco Bay region, and south to Monterey Co. on the 

 sandy coasts. Above Copperopolis, Calaveras Co., J. B. Davy 

 approaching G. staminea.

Annual, a span to two feet high, branching or simple, glabrous 

 or nearly so, except the inflorescence which is more or less 

 densely white- woolly; leaves two or three inches long at the base

 tifid; inflorescence terminal on long naked peduncles, a dense 

 cymose cluster, not strictly a head, often elongated; calyx two 

 to three lines long, mainly hyaline, lobes short- triangular, very

San Diego Co. to San Joaquin Co. in the foothills, not on 

 the sandy coast. This is G. achilleaefolia Benth. according to 

 J. D. Hooker, "Botanical Magazine," t. 5939; not G. achilleae- 

 folia Benth. according to W. J. Hooker, "Botanical Magazine," 

 t. 3440 which is Gray's G. multicaulis, also Greene's. (Plate 4.)

Annual, a foot or so tall, rather slender, not at all glandular, 

 but the arachnoid pubescence sparse on the petioles and dense 

 on the calyc.es, otherwise glabrous; inflorescence capitate con-
