1. Shepherdia canadensis (L.) Nutt. (Lepargyrea canadensis (L.) 

 Greene.) Russet Buffaloberry. Map 1460. Near the bases of low dunes 

 near Pine in Lake County where it is infrequent. In 1906 I found it about 

 2 miles east of Indiana Harbor. City development is fast encroaching upon 

 its native area and it will soon become extinct in Indiana. It is the first 

 shrub of Indiana to bloom and it is soon followed by leatherwood and 

 certain species of willow.
