Distribution. Eastern, Central, and Western Alps ; Europe, 

 Central and Northern Asia, N. America. British. 



Pyrola media Swartz.

 longer, and from the last in never being so curved. The flowers 

 are variable in size. 



Woods and moist, shady places ; not very common. June, July.

 and in the Caucasus ; Armenia, Northern Asia, extreme north of

Leaves on long stalks as in the 2 last, broadly ovate, rather 

 thick, entire or slightly crenate. Flowers drooping in a short, loose 

 raceme. Sepals short and broad, rather triangular. Petals con- 

 nivant, ovate or orbicular, quite free, closing over the stamens,
