 style about a line long; cells 6-ovuled. — Vesicaria pallida, Nutt. in Torr. & Gray, Fl. i. 

 668. V. grandijiora, var. pallida, Torr. & Gray, 1. c. 101. — Prairies near San Augustine,

 a foot high or less : leaves entire, oblong-oblanceolate or -spatulate, an inch long or less : 

 petals spatulate, 1| to 3 lines long: pods sessile, 1 or 2 lines broad; the very slender style
