This plant is of special interest because it is the first species of the great American 
group of T'omentosae which has been found in the Old World. It thus forms another 
important link between the floras of eastern Asia and eastern North America. 
It has the small late flowers, the small, soft and succulent fruit, and the obtuse 
nutlets deeply grooved on their inner faces, peculiar to the American species. The 
thin leaves with veins only slightly impressed on the upper surface place it with 
C. tomentosa Linnaeus and the other thin-leaved species of the group which are 
abundant in the Mississippi valley but are rare east of the Appalachian Mountains 
and do not extend to the Rocky Mountains. 
S ioiceph of C. Wilsonii will be found under No. 082 of Wilson's photo- 
graphs.
