1. Chelone obliqua L. var. speciosa Pennell & Wherry. (Bartonia 10: 

 19. 1929.) (Chelone obliqua of Gray, Man., ed. 7 and Britton and Brown, 

 lllus. Flora, ed. 2.) Rose Turtlehead. Map 1819. Usually found in low 

 woods and less frequently in springy places in woodland. 



Ind. to Iowa and Ark. 



2. Chelone glabra L. var. typica Pennell. White Turtlehead. Map 1820. 

 Pennell has divided Chelone glabra into several varieties and forms, five 

 of which he cites from Indiana. For the benefit of those who wish to study 

 this species intensively I have listed these forms and given their distri- 

 bution. The species and its forms grow in wet woods, springy places about 

 lakes, along streams, and in marshes.
