Common in damp woods in the Northern and Middle districts, 

 and locally in the Cape May peninsula. 



The familiar Jack-in-the-Pulpit is one of those plants that 

 disappears as soon as we enter the Pine Barrens. In northern 

 and western Jersey we find it in damp woods associated with the 

 Sklink Cabbage, Dog-toothed Violet, Spring Beauty and May 

 Apple, but in the swamps of the Pine region not one of the 

 group is to be found.

This little "Jack" occurs with the preceding, blooming a couple 

 of weeks later. It is easily distinguished by its smaller size, 

 more erect "flap" to the spathe, which is always deep purplish 

 inside, and by the shiny green (not glaucous) under surface to 

 the leaves. It was first noted in our district by Mr. Stewardson 

 Brown at Clementon. 



Fl. — Early May to late June.
