Rosa acicularss Lindl. Wild Rose. 
All of the roses of the acicularis group in this region are much in need 
of careful study. The writer has been unable, thus far, to make any 
definite division among them, although there are wide variations in stem, 
leaf, and fruit characters. The relationship of var. Bourgeauiana is not 
clear, since the shape of the mature fruit is so inconstant. On a granite 
hill at the east shore of lake Mamawi there is a form with very much 
elongated fruits that has also been placed in this species for the time being. 
Abundant in woods, clearings, prairies, and on rocky hills throughout 
the park area. Flower buds have been found June 9 and 13, but the height 
of the flowering season occurs in late June and the first half of July. 
Immature fruits appear during the third week in July, and mature ones in 
August. The wild roses are among the most abundant and striking summer 
flowers in the region. The fleshy part of the fruit is often used for food.
