11. LANGLOISIA Greene 



Low annuals. Leaves alternate, linear to cuneate, regularly toothed as if shal- 

 lowly pinnatifid, the lower teeth or segments replaced by long bristles, the upper 

 teeth or segments bristle-tipped. Flowers in terminal braeteate heads, the bracts 

 with bristle-tipped lobes. Calyx-lobes equal, bristle-tipped, in fruit splitting to 

 base. Corolla showy, tubular-funnelform, 2-lipped with usually 3 lobes in the up- 

 per lip and 2 in the lower, or regularly 5-lobed with the lobes only obscurely dis- 

 posed in 2-lipped fashion. Stamens inserted in the corolla-throat, the filaments 

 exserted from the throat and often somewhat declined. Capsule 3-sided, 2 to 

 9-seeded ; seeds somewhat mucilaginous when wetted. — Species 5, western North 

 America. (A. B. Langlois, a botanist of Louisiana.) 



Leaves abruptly dilated at apes from a narrow base, the lateral bristles 2 or 3-forked or simple; 

 corolla regular; stamens shorter than corolla-lobes; capsule cells 3 to 9-seeded. 



Corolla-lobes not dotted, about % as long as tube; capsules 2 to 3^! lines long 



1. L. setosissima. 



Corolla-loljes purple-dotted, nearly as long as tube; capsules 3 to 5 lines long.... 2. L. punctata. 



Leaves linear to spatulate in outline, the rachis broad or ligulate, the lateral bristles simple ; corolla 



strongly bilabiate ; stamens as long or longer than the corolla-lobes, at least longer than 



the lower lip, strongh' declined; capsule-cells 2 to 6-seeded. 



Corolla 5 to 7 lines long, the lobes linear to oblanceolate, acute or acutish or tapering at tip, 



the upper lip without appendages in the sinuses ; calyx nearly as long to longer than 



corolla-tul)e 3. h. schottii. 



Corolla 7 to 9 lines long, the lobes oblong, truncate or truncatish and toothed at tip ; sinuses 

 of the upper lip of the corolla with a small palate-like process turned inwards in 

 the notch; calyx % to % as long as corolla-tube 4. L. matthewsii. 



1. L. setosissima Greene. Plant low or depressed, 1 to 9 inches broad, the main 

 axis usually sliort, erect, 14 to 2t4 inches high, the branches spreading horizontally 

 or ascending; herbage subglabrous to puberuleiit ; leaves 6 to 11 lines long, cuneately 

 and somewhat abruptly dilated upward from a slender petiolar base, 3-toothed at 

 apex and with 1 or 2 pairs of teeth below these, all bristle-tipped, these bristles sim- 

 ple or sometimes 2 or 3-forked, the broad petiolar base with 2 to 7 pairs of 2-forked 

 bristles on the margins; calj-x-lobes (to tips of bristles) % to nearly as long as 

 corolla-tube ; corolla lavender-blue, regular or nearly so, 7 to 9 lines long, the lobes 

 1 to 11/2 lines wide, about 1 -i as long as the tube ; capsule 3-sided, narrowly ovate to
