Stem () — 12 inches hi*(h. glabrous, ascending or erect, 

 stout, simple or branched ; leaves ol)long or obovate-oblong, 

 dentate or denticulate, 3— 5-nerved, acute or obtusish at 

 the apex, narrowed at tlie base: peduncles about the same 

 length as the calyx, stout; alyx-lobss linear; corolla 

 about twice the length of tlie calyx, its tube yellow, the 

 limb paler; sterile filaments wanting; capsule globose, 

 about three lines in diameter. 



Dr. Mohr, in his Plant Life of Alabama, gives the range 

 of this species as: "Coast of New Jersey, West Virginia, 

 southern Illinois, southern Missouri and Arkansas, south 

 to Florida and Texas." This range would place Iowa 

 north of the supposed range of the species. In our herba- 

 rium is a series of specimens from Decatur count,y, lowa^ 

 collected by J. P. Anderson, June 23, 11)00. The plants are 

 typical, being glabrous and having the very shoi't stout 

 peduncles, and large globose capsules. We also have two- 

 sheets from Virginius H. Chase, collected l)y him near 

 Wady Petra in Stark county, north central Illinois, dated 

 June 30, 1898, and June 22, 1899. This gives a considera- 

 ble northward extension of the heretofore known range of 

 the species. Wet soil and shallow^ water seems to be the' 

 usual habitat, and the species is said to bloom from June 

 until September. We believe this to be the first report of 

 the species from Iowa. Elliott gave the type locality asr 

 "Grows in ponds four miles from Charleston, on the Neck."^
