occurrence well up the valley of the Schuylkill River toward the 

 Blue Mountains, it is doubtless to be associated with the notable 

 group of plants of austral affinity including the Papaw, the Red 

 Pud, the Persimmon. It is prcjbably to be classed among Caro- 

 linian types. 



An apparent local center of abundance near Philadelphia, as 

 shown by stations, is, I believe, quite illusory and due mainly to 

 the more extensive work which has been carried on in this 

 immediate vicinity. The several days of systematic exploration 

 in the Fleetwood region of Berks County, coupled with a knowl- 

 edge of the plant and its possibility there, demonstrated its 

 occurrence in two localities. 



It is of Hkely occurrence at least throughout southeastern 

 Pennsylvania and immediately adjacent New Jersey, following 

 well up the Delaware, as Mr. Mackenzie's station at Milford 

 shows. In the southern portion of New Jersey it will probably 

 be found to be closely confined to the richer soils along the streams 

 of the Delaware system. No doubt were the lower Susquehanna 

 valley as thoroughly explored as the lower Delaware, the plant 

 would be shown to have a wider distribution there than only 

 along the Conestoga.
