 peduncled clusters, scarlet or red; corolla tubu- 

 lar-funnelform, the tube l'-l#' long, slightly 

 thicker upward, the limb cleft into ovate or 

 lanceolate acute or acuminate spreading or re- 

 curved lobes; stamens unequally or about equally 

 inserted in the throat; ovules numerous; seeds 

 mucilaginous and emitting spiral threads when 

 wetted.

 Coulter) to Texas and Mexico, west to British 

 Columbia and California. June-Aug. 



5. Gilia pinnatifida Nutt.

Biennial or perennial from a deep root, much 

 branched, viscid-glandular, 6 / -2 high. Leaves

 the segments linear-oblong, sometimes toothed, 

 obtuse or acutish, 2 // -6 // long, those of the stem 

 alternate, smaller, the uppermost minute and 

 entire; flowers very numerous, small, panicu- 

 late, some sessile, some petioled; calyx 5-lobed, 

 the lobes lanceolate to ovate; corolla salver form, 

 3"-5" long, the limb violet or blue, its white 

 tube longer than the calyx and its obovate lobes ; 

 stamens exserted; seeds not mucilaginous nor 

 emitting spiral threads when wetted.
