pointed, upper surface white; fruit a red berry. 



1. Calla palustris L. Fig. 3, Map 4 



Common throughout New England in wooded swamps, marshes, 

 and bogs and along marshy shores of rivers, ponds, and lakes. Range 

 extends from Newfoundland and Labrador to Alaska, south to 

 northern New Jersey, Pennsylvania, northern Indiana, Wisconsin, 

 and Minnesota. 



Symplocarpus (Skunk-cabbage) 



Emersed perennial, growing from a stout erect rhizome; leaves 

 ovate to cordate, short-petioled; flowers perfect, borne on a spadix, 

 subtended by a mottled purplish-green and/or reddish-brown spathe; 

 ovaries imbedded in spadix; fruit a globular or ovoid mass; entire plant 

 producing a foul skunk-like odor. 



1. Symplocarpus foetidus (L.) Nutt. Fig. 4, Map 5 



Widely scattered in northern New England, common in southern 

 New England in wet woods, meadows, swamps, bogs, and along 

 stream borders. This is one of the earliest plants to flower in New 

 England, with the flowers emerging in March, followed by leaf 

 emergence in April. Range extends from Nova Scotia and Quebec west 

 to southeastern Manitoba, south to Georgia, Tennessee, Ohio, Indiana, 

 central Illinois, and Iowa. 



The Araceae also include Arisaema triphyllum (L.) Schott (Jack- 

 in-the-pulpit) and Arisaema dracontium (L.) Schott (Green Dragon), 

 which are occasionally found in wet woods or on alluvial plains. These 

 are not included in the treatment since we do not consider them to be 

 truly wetland species. There is a record of Pistia stratiotes L. collected 

 from the Concord River, Massachusetts. This species is not winter 

 hardy and surely was introduced into the river the summer it was 

 collected.
