« Cornus florida Linnseus (and its varieties) and Cornus nuttallii Audubon, the so-called flowering dog- 

 woods, differ from our other arborescent species in having their flowers surrounded by a corola-like involucre 

 composed of from four to six showy white (sometimes pink) bracts. Because of their showy appearance, 

 these bracts are popularly often taken to be petals of the true flowers, which are, however, small greenish 

 bodies situated in the center of this showy involucre. On account of this difference in the structure of the 

 flower clusters of these two species J. K. Small (Flor. S. E. U. S., 854, 1903) and Britton and Shafer (North 

 Am. Trees, 744, 1908) have taken up for Cornus florida Linnaeus the name Cynoxylon floridum (Linnseus) 

 Rafinesque, and for Cornus nuttallii Audubon, Cynoxylon Nuttallii (Audubon) Shafer. The writer psefers 

 to retain these popularly well-known trees in the genus Cornus
