Arum virginicuin Linnaeus, Sp. PI. 966. 1753 [Virginia]. 

 Peltandra virginica Knieskern 29. — Willis 58. — Britton 253. 



Plentiful, growing in water along the edges of all the rivers 

 and tributary streams of the State. 



Along the muddy shores of the Delaware and the tidewater 

 creeks below Philadelphia its broad arrow-shaped leaves are 

 familiar, mingling with the similar but more delicate ones of the 

 Sagittaria and the rounder ones of the big yellow Splatterdock, 

 the three forming a sort of border to the beds of Wild Rice 

 and Cat-tails. 



The flower, which resembles a very slender green calla lily, 

 raises itself among the leaf stems for a short tiniiC, and then, as 

 the seed develops, the stalk curves downward, drawing the pod 

 beneath the water and burying it in the soft mud. 



Arrow Arums frequently follow the smaller streams far back 

 toward their sources, and we come upon them sometimes even 

 in the Cedar Swamps of the Pine Barrens where some oi these 

 tidewater or river associates have succeeded in penetrating. Mr. 

 Ivar Tidestrom (Rhodora 191 o. 47) proposes to separate two 

 varieties based on leaf form, but I cannot regard them as any-
