44 FIELD COLUMBIAN MUSEUM BOTANY, VOL. 2. 



Allison Islands of the shoal. These plants have leaves varying from 

 exact counterparts of the last to sinuate-dentate, and sinuate-cleft 

 forms, while the fruits of both the last forms appear indifferently 

 upon these. 



[Specimens of this species gathered on the shores of Lake Michi- 

 gan, near Chicago, are fully as variable as these from the West 

 Indies; clumps in various localities yielding forms that might be 

 placed under either this or Americana as described, and others that 

 intermix both. (Herb. Field Col. Mus., Lansing, Nos. 10, n, 330, 

 417, 449.)]
