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.
