Impatiens sp. 
These specimens are too young to be identified, and although they are 
mere seedlings they have produced some cleistogamous flowers and fruits. 
All of the material (about seventy plants) came from a space about 10 
inches in diameter, from about eighty seeds which still cling to the roots. 
Found in the moss mat of a timbered, upland muskeg.

little more hairiness on the veins of the leaves than in canadensis, but 
the presence or absence of “ underground stolons ” seems of doubtful value
