Erect perennials, with angled steins, and opposite peti- 

 oled leaves. Flowers axillary, nearly sessile, in clusters; 

 calyx with three bracts, 5-parted, segments ovate or lan- 

 ceolate. Carolla tubular, inflated, 2-lipped, much longer 

 than the calyx; the upper lip arched, notched at the apex 

 or entire, the lower lip 3-lobed, bearded in the throat. 

 Stamens four, with woolly filaments and anthers, the fifth 

 anther rudimentary. Seed with a membraneous wing. 



Chelone glabra L. Sp. PI. 611. 1753. 



Chelofie glabra \a.x . aMa Pursh, Fl. Am. Sept. 2:427. 1814. 



Stem slender, 1 — 5 feet high; leaves sessile or short-peti- 

 oled, narrowly lanceolate, tapering both ways, appressed 

 serrate; flowers clustered, white or roseate, bracts not cili- 

 olate. 



This species ranges from Newfoundland to Florida, 

 west to Manitoba and Kansas. The species grows in 

 swamps and wet places, blooming from July until late in 

 September, and in Iowa it is rather infrequent and seems 

 to be found only in the eastern portion. Type locality: 

 "Hab. in Virginia, Canada." 



Specimens in our collection are from Winneshiek and 

 Johnson counties. The State University herbarium has 

 specimens from Allamakee, Dubuque, and Muscatine coun- 

 ties. Prof. Fink reported the species from Fayette county.
