 Barely collected. 



4. H. corymbosa (DC.) T. & G. Coast Tarweed. Corymbosely and wide- 

 ly branching, 1 to l 1 /. ft. high, hirsute-pubescent and glandular; radical 

 and often some lower leaves pinnately divided into linear lobes, the upper and 

 those of the flowering branches linear and entire; heads % in. high, 7 to 10 

 lines broad; rays 12 to 25, oblong-cuneate, 2 to 4 lines long, 3 or 4-toothed; 

 pappus of the sterile disk-achenes of minute finibriate-bristly scales, or of 

 entire scales, or none; ray-achenes with a short upturned beak on the inner side 

 at apex. — (H. angustit'olia DC.) 



Abundant in valley fields and on hillsides: Berkeley to Santa Cruz and 

 Monterey Co. June- July. 



5. H. kelloggii Greene. Erect, paniculately branching, iy 2 to 2y 2 ft. 

 high, the heads on slender pedicels; herbage mostly hispid below and glandular 

 above; leaves linear and entire, those of the filiform flowering branchlets very 

 short; lower leaves pinnately parted; heads narrow; disk-flowers about 6 or 7; 

 ray-flowers 5, the ligules 2 to 2^L> lines long; ray-achenes slightly curved, 

 roughened on the beak and sides, and with a curved or upturned beak at the 

 summit on the inner side; pappus of about 9 linear paleae which are irregularly 

 lacerate at summit and almost or quite as long as the tube of the corolla, 

 united only at base or almost to the summit. 



Antioch to the San Joaquin Valley where it is abundant in low grain fields 

 near the river. July-Aug. 



6. H. fasciculata (DC.) T. & G. Paniculately branched above the base, 

 % to 2 ft. high, sparsely hirsute and hispid, or disposed to be nearly glabrous 

 above ; radical leaves pinnately parted; stem leaves linear, either laciniate- 

 pinnatifid, few-toothed or entire, those of the branchlets shorter and mostly 

 entire; heads usually fascicled in rather dense small clusters; bracts of the 

 involucre glabrous or glandular-hispidulous, those of the involucre slightly 

 united; disk-achenes with a pappus of 6 to 10 linear paleae lacerate at tip; 

 ray-achenes smoothish or transversely rugose, with a very short beak. 



Mt. Diablo Range southward to Monterey Co. and Southern California. 



7. H. virgata Gray. Stem commonly branching at the middle into several 

 virgate branches bearing numerous racemosely disposed heads on short lateral 

 branchlets; herbage glabrous or nearly so; branchlets crowded with linear 

 leaves about 1 line long, those (particularly of the flowering branchlets) ending 

 in a truncate or somewhat saucer-shaped gland; involucre oblong, its bracts 5, 

 with involute tip ending in a truncate gland and stipitate-glandular on the 

 back; ray-flowers 4 or 5 ; disk-flowers 7 to 10. 



Common on the plains of the Sacramento Valley (Suisun, Vanden, Gait, 

 etc.) and the San Joaquin Valley and in the valleys of the inner South 

 Coast Ranges. Southern California. Aug.-Oct. 



8. H. heermannii Greene. Stems paniculately branched, 1 to 3 ft. high; 

 herbage viscid, pubescent, heavy-scented; leaves of the flowering branchlets 

 minute, scattered; involucre hemispherical, its bracts beset with stalked glands; 

 ray-flowers 5 to 8, disk-flowers 10 to 15; ray-achenes with a somewhat con- 

 spicuous beak and stipe. 



Mt. Diablo Range southward to Kern and Ventura cos. 



48. HOLOCARPHA Greene. 

 Corymbosely branching annual with very viscid-glandular herbage. Leaves 

 of the axillary fascicles and those about the heads narrowly linear, beset with
