 petals light purple, 4 - 9" long, cuneate-obovate, more or less deeply 

 2-lobed ; stigmas ovate, united toward the base, apparently yellow 

 (" purple," Durand) ; capsule 6 - 9" long, puberulent, attenuate at the 

 apex, abruptly contracted into a pedicel about 1" long. — " Sacramento

 ored ; calyx funnelform, the segments erect; petals obovate-cunei- 

 form, 2-lobed, purple to white ; filaments slender, the petaline 

 shorter ; anthers short, attached below the middle ; capsule mem- 

 branous, ovate-oblong to linear-cylindric, nearly terete, acute, 

 sessile, the sides ribbed, sutures thin, dehiscent to the base ; seeds 

 ascending, few (3 - 8) in each cell, ovate-oblong, smooth ; flowers 

 small, solitary in the axils of a leafy compound or simple spike, 

 diurnal. Annuals, erect, simple or branched. 



66. CE. densiflora, Lindl. Strict, ^ - 1° high, canescently pu- 

 bescent and more or less villous ; leaves lanceolate to linear-lanceolate, 

 1 -3' long, acuminate, sessile, mostly denticulate, the floral usually 

 much shorter and broader ; flowers usually in close terminal or nu- 

 merous short lateral spikelets ; calyx H - 3" long, the petals about 

 twice as long ; capsule ovate-oblong, 2 - 4" long, 1|" broad at base, at- 

 tenuate upwards, smooth or slightly villous, the cells 3 - 6-seeded, the

 Rather variable in the form of leaves and bracts, in the character and 

 degree of pubescence, and somewhat so in the inflorescence. 



67. QE. Torreyi. Rather slender, branched, | - 1^° high, villous 

 throughout with short, stiffish, spreading hairs ; leaves linear to lanceo- 

 late, 4 - 9" long, entire or subdenticulate, usually attenuate to the base, 

 the bracts similar and scarcely smaller ; spike simple, loose ; flowers 

 very small, 1 - 2" long, purplish ; capsules linear, 4 - 6" long, 1" wide, 

 acuminate, the cells 6 - 8-seeded ; placenta narrow, the valves septifer-
