Diodia teres 

 var. setlfolia Fern. & Grisc. 



Unusual common names are Pond Dogwood (Lower Wabash Valley), 

 Flowering Ash (Shelby County), and Swamp Sycamore (Jay County) 

 because the fruit resembles that of the sycamore. 



N. B., Ont. to Calif., southw. to Fla. and Tex. ; also in e. Asia. 



la. Cephalanthus occidentalis var. pubescens Raf. Hairy Button- 

 bush. Map 1911. This variety is found principally in the southern half 

 of the state. Our only report from northern Indiana is that of Peattie 

 from Lake County. I have looked closely for this in Lake County without 

 success. I could not find Peattie's specimen. 



The habitat is the same as that of the species but it is rarely found with 

 it. 



Ind., southw. to Ga., La., and Tex. 



8451. MITCHELLA L. Partridgeberry 



1. Mitchella repens L. Partridgeberry. Map 1912. In all parts of 

 the state where there are areas of slightly acid soil. I have never seen 

 it associated with lime loving plants. The map covers the area of all of 

 the reports except one in Lake County where its habitat occurs. It is 

 usually found in low, flat sweet gum and beech woods, on the crests and 

 slopes of sandstone ridges, and in the black sand of black and pin oak 

 woods of the northern part of the state. 



N. S., Ont., and Minn., southw. to Fla., Ark., and Tex.
