Wake Robin, illustrated in the cuts, inhabits cold, damp, 

 often mountainous woods, from Canada to Georgia. It is 



known by its petiolate leaves, 

 pedunculate flower, and white, 

 purple-veined petals. 



T. erectum, the Bath-flower, 

 abounds in rich woods, especially 

 Northward. The leaves are sessile, 

 the flower pedunculate, and the 

 petals dark-purple, ill-scented. A 

 variety has white petals. The stu- 

 dent will analyze the various 

 species when found, and note in 

 his Plant Eecord their specific 

 characters.*

 called from its white, fleshy rhi-

 a simple, slender stem, about 2 

 feet high, bearing a whorl of 6-8 

 leaves near its middle, another of 3 leaves at the top,
