 glabrous or sparingly pubescent at the dilated base of the short petioles : peduncles erect or 

 ascending, somewhat enlarged above, twice or thrice longer than the leaves, silky-strigillose : 

 spikes cylindric, 2-6 cm. long, 6-8 mm. thick, dense : flowers perfect : bracts deltoid-ovate, 

 not equalling the calyx-lobes, scarious-margined : calyx-lobes more or less silky, oval to 

 cuneate, about 3 mm. long, scarious-margined : corolla glabrous ; lobes reflexed, ovate, 

 cordate, 3-3.5 mm. long, obtuse, violet at the base : capsules broadly oblong, 4 mm. long, 

 rounded at the apex, surpassing the calyx-lobes : seeds 2, about 3 mm. long, brown.

8. Plantago inflSxa Morris. Annual, villous to matted-tomentose. Leaves alter- 

 nate, ascending to erect, 10-20 cm. long ; blades oblanceolate-linear, acute and callous- 

 tipped, 5-7-nerved, entire or with scattered teeth : peduncles ascending to erect, very
