corners. The seeds are surrounded with a reticulated, spongy 

 membrane. The embryon stands erect in the albumen. 



Diagnosis and Affinity. 



This species could only be confounded with Pyrola mu 

 nor. But P, minor has its leaves more rounded, obtuse, 

 slightly serrated ; it has pale red flowers, which are not 

 turned to one side only, but to several. The other species 

 are still more dissimilar. The genus Pyrola is most nearly 

 related to the Chimaphila Pursh, which is distinguished 

 merely by a thick, circular stigma, which, without a pistil- 

 lum, is placed immediately upon the germen. It borders on 

 GauUheria, Clethra, Diapensia^ Andromeda, Monotropa^ 

 and Erica, along with which it forms the family of the Eri- 

 cese.
