DovuBTFUL AND EXCLUDED SPECIES 
PYROLA ROTUNDIFOLIA L. Sp. Pl. 396. 1753. This is a European species, for which P. 
americana has been mistaken. 
PYROLA URCEOLATA Poir. in Lam. Encyc. 5: 743 (1804), is Galax aphylle. 
Pyroua FLExvosa Raf. Atl. Jour. 151. 1832. ‘This is wholly unknown. 
PyROLA ROTUNDIFOLIA INCARNATA DC. Prodr. 7: 773 (1839) (P. incarnata Fisch.; DC.

and erect, without a collar; stigma peltate, thicker than the style, with 5 marginal spreading 
papillae. Capsule depressed-globose, umbilicate, 5-valved, dehiscent from the base upwards,
