EXPLANATION OF PLATE 94. 
Fig. 1. Peltandra virginica f. latifolia (Delaware, Commons. Not an ex- 
treme of the form). 
Fig. 2. P. virginica f. rotundata (leaf from type sheet). 
Fig. 3. P. virginica f. hastifolia (Michigan). 
Fig. 4. P. virginica f. brachyota (leaf from type sheet). 
(The three other forms were well figured by Mrs. Chase in Ruopona for March, 1910.) 
1 It may be well to mention that the youngest leaves of the seedling (as shown by 
sheets collected by Walter Deane on shore of ''Glacialis," Cambridge, Massachusetts, 
May 20, 1894) are of this type, suggesting that it represents the primitive leaf-form 
in the species.
