EXCLUDED SPECIES 
CHIMAPHILA UMBELLATA (L.) W. Barton, Veg. Mat. Med.1: 17. 1817. (Pyrola umbellata 
L. Sp. Pl. 396. 1753.) This is a European species with which our American species has been 
confused, differing from C. corymbosa in the smaller subovoid capsule, which is thicker below 
the middle, ovate sepals, longer than broad, shorter stamens, and obtusish leaf-blades. 
Alefeld, who distinguished the two, admitted C. umbellata to the west coast, but his specimens 
were evidently depauperate northern ones of C. occidentalis.
