its teeth very short and broad ; fruit and fruiting calyx not 



Known only as collected by the late Father I^anglois, in 

 prairies near Eunice, Louisiana, 12 Sept., 1894. 



Gerardia asprella. Annual, 2 feet high or less, loosely 

 and widely branching above the middle ; everywhere muricu- 

 late-scabrous, but the roughness shorter than in the preceding : 

 leaves narrowly linear, not acute, strongly revolute, those of 

 the inflorescence more lance-linear and with clear distinction 

 of blade and petiole : flowers mostly alternate, distinctly and 

 rather slenderly pediculate : calyx under corolla (the fruiting 

 not known) marked by 5 raised and very scabrous veins run- 

 ning each to the end of the short deltoid and incurved tooth : 

 corolla % inch long or more, its tube rather narrow and not 

 ventricose, the limb notably wide in proportion, the throat, 

 and also the stamens long- hairy. 



Near St. Martinsville, Louisiana, 27 Sept., 1892. A. B. 

 Langlois. The collector, taking under consideration the rough- 

 ness of the plant, and its only middle-sized and rather narrow 

 corollas, had labelled his specimens G. aspera Dougl., to which 

 the plants bear no particular resemblance. 



Steironema gramineum. Small, rather weak and delicate 

 but upright, 7 to 11 inches high, clothed throughout with very 

 narrow linear leaves mostly 2 to 3 inches long, often subfal- 

 cately curved, neither very firm nor yet flaccid, sessile, the 

 pairs almost connected at base and there with a substipular 

 fringe as a connective, the blades all plane, entire, acute : 

 flowers very small, mostly solitary and much scattered ; calyx- 

 segments triangular-lanceolate, attenuate-acute : corolla cleft 

 almost to the base into oblong-obovate or oval cuspidate lobes, 

 these dark-dotted ; bases of the lobes granulate, but hardly so 

 the long filiform filaments which greatly exceed the short 



oblong-oval anthers. 



Species small and almost grassy by the narrowness of its 

 foliage, known only by two sheets in U. S. Herb., col-
