I received specimens of this plant, in fruity about eight 

 years since, from Dr. Ed to in J a m e s, who discovered 

 it at Greenbush, near Albany. Having only seen imper- 

 fect specimens, I was ignorant of the structure of the flowers, 

 but referred it to Monotropa as the genus to which it was 

 most nearly allied, and a short description was published in 

 £ Q t on's Manual of Botany, ed. 2d. 1818, under the name 

 of M. firocera. There can, however, be no doubt of its be- 

 longing to a genus quite distinct from Monotropa. This 

 plant is said, by Mr. M'uttall, to be an evanescent annual, 

 but I am assured by Mr. Tracy^ of Albany, an accurate 

 Botanist, that it is certainly a perennial. He has taken up 

 the roots from their native soil, and transplanted them into 

 his garden, where they flowered. I am informed that the 

 Pterospora has lately been illustrated in Europe by Ho ok er^ 

 and also by Lindley and Drown; but unfortunately their 

 publications have not yet reached this country, so that I am 

 unable to avail myself of their valuable observations.
