626 REPORT OF NEW JERSEY STATE MUSEUM. 



V. corymhosum is admittedly wide ranging, and the evidence 

 is suggestive that the other forms are to be found materially 

 north of the New Jersey coastal plain, unless it be found that 

 the more northern specimens have distinctive floral characters. 

 If not, it seems possible that some older names may have to be 

 considered in straightening out the nomenclature of the group. 

 Provisionally, however, the New Jersey plants had better be 

 named in accordance with Mr. Mackenzie's conclusions.
