 calyces implexed- woolly; four of the calyx-teeth short, the fifth as 

 long as the tube; corolla deep blue, the tube 6 lines long, 2 or 3 times 

 the length of the calyx, its lobes oblong, about 2 lines long. 



Mountains of Santa Clara Co. and southward to Southern Cali- 

 fornia. June-Sept. 



9. G. intertexta Steud. Stems simple or often branching from 

 the base, 2 or 3 to 7 in. high, white-puberulent but not glandular; 

 leaves bipinnatifid and the segments spinescent-tipped; body of bracts 

 and exterior of calyx-tube densely white-villous or wooUy-tomentose; 

 corolla white or pale blue, equaled by the calyx-teeth.

10. G. leucocephala Benth. Stems simple or branching from

 the divisions filiform and entire, sparingly toothed, the rachis broad 

 and often prolonged into an elongated terminal entire division; 

 flowers clear white, i lines long; calyx with a tuft of hairs at each 

 sinus, the teeth mostly entire and nearly equal. 



Low places in fields and beds of pools where water has stood in

 ramento Valley; Vacaville; Winters; first collected on plains near 

 the Feather River by Hartweg. May-June. 



11. G. prostrata Gray. Plants glabrous; primary flower-cluster 

 sessile, the branches radiating from beneath it, simple or once forked, 

 terminating in the head-like clusters; leaves pinnatifid, the rachis 

 broad and slender, the segments remote; heads- dense, surrounded by 

 foliaceous bracts 1 to IJ in. long; bractlets not exceeding the white 

 fiowers; corolla-lobes oblong; calyx with unequal teeth, the two 

 longer tridentate; calyx-teeth in fruit contracted over the 2-celled 

 capsule; seeds 9 to 11', small; embryo short-cylindrical, the cotyledons 

 about equaling the caulicle in length. 



Plains of central California southward to Los Angeles. 



12. G. cotulsefolia Steud. Erect, 7 to 13 in. high, finely pubes- 

 cent; leaves bipinnatifid, the segments innocuous; bracts and calyx 

 slightly hairy or glabrous at the base; flowers creamy-white, com- 

 monly 4-merous; calyx-lobes varying from nearly equal and entire to 

 unequal, with the longer variously toothed; capsule 1-celled, 4-valved,

Valley fields: Newark, Alameda Co.; North Coast Ranges; Sac- 

 ramento Valley. Scentless ace. to Greene. Navarretia nigellseformis
