Pentstemon. These two genera have been divided by the 

 former having- woolly anthers, and the latter smooth ones ; 

 and supposing that this were really the essential distinction 

 between them, the subject of this notice would belong to 

 Pentstemon. Others have distinguished the genera by the 

 form of the flower, ascribing to Chelone a corolla short, 

 inflated, and contracted at the orifice, with winged seeds; 

 and to Pentstemon a funnel-shaped corolla, with angular 

 seeds; in this vi^w of the subject the latter would still be the 

 station of the present species. It is only when the genera 

 Chelone and Pentstemon are merged into one, in which case 

 the former name supersedes the latter, that Chelone can be 

 the proper appellation of our plant; and this combination is, 

 it is needless to say, any thing rather than a judicious one. 

 1 therefore agree with Mr. Bentham ( ScrophulariacecB indicce, 

 p. 7.) in striking out of the genus Chelone all the plants 

 hitherto referred to it, with the exception of C. Lyonii, 

 glabra^ ohliqua, and nemorosay and in placing all the others 

 in Pentstemon.
