MANUAL OF POISONOUS PLANTS 



Gentians are pretty flowers, but few of them are cultivated. The prettiest 

 of these are the closed gentian (G. Andrewsii) , with large blue flowers, the 

 white closed gentian (G. flavida), the fringed gentian (G. crinita), and the 

 Texas lily (Eustoma Russellianum) , native from Texas to Nebraska and intro- 

 duced into Colorado, with handsome large blue and white flowers.
