 white, 7-10 mm. long, the slender tube abruptly expanded into the large limb; 

 style 2-parted; fruit ellipsoid, bicarpellate, 5-8 mm. long, to 5 mm. in diameter, 

 glabrous to villous, crowned with 2 or sometimes 3 lanceolate more or less 

 pubescent calyx teeth; carpels suberose-crustaceous, 3-ribbed on the back, held 

 together by a thin epicarp that rarely ruptures. 



In swamps, wet meadows, marshes, coastal prairies and in mud along streams 

 and about ponds, in e. third of Tex. and Okla. (McCurtain, Latimer, Sequoyah, 

 LeFlore and Choctaw cos.), May-Oct.; from Fla. to Tex., n. to N.J., 111., Mo. and 

 Okla.

Plant diffusely spreading or ascending from an annual but sometimes lignescent 

 root, rigid, puberulent to hirsute; stems and branches to about 8 dm. long, terete, 

 rather quadrangular above; leaves linear to lanceolate, rounded to somewhat 

 clasping at the sessile base, acute to acuminate at the apex, rather rigid and often 

 with revolute margins, more or less scabrous, to 5 cm. long and 1 cm. wide, 

 usually much smaller; stipular bristles numerous, filiform, often reddish-brown, 

 usually equaling the flowers and surpassing the fruit; corolla funnelform, whitish 

 to pinkish-purple, 4-6 mm. long; style undivided; fruit obovate-turbinate, not 

 ribbed, commonly hispid or hispidulous, about 4 mm. long, bicarpellate, crowned 

 with usually 4 somewhat unequal ovatish ciliate calyx lobes, when carpels separate 

 often 3 lobes on one carpel and 1 on the other. Incl. var. angustata Gray. 



In sandy soils in woodlands and open areas in mud along streams, in ditches, 

 swamps, bogs, in the e. two thirds of Tex., rare on the Edwards Plateau, and 

 Okla. (McCurtain and Ottawa cos.) to Ariz. (Greenlee, Gila, Cochise, Santa 

 Cruz and Pima cos.), May-Nov.; from Fla. to Tex. and Ariz., n. to N.E., O., 

 111., Mo. and Okla.
