TREES AND FLOWERS OF 

 (white) (white) 



MEADOWSWEET THIMBLEBERRY 



Meadowsweet (Spiraea). This shrub is distribut- 

 ed along the edges of timber throughout the Park, and 

 ventures a little into the open in moister places. It 

 does not form a dense bush, but sends up its slender 

 stems singly or only a few together. The flowers are 

 white and very tiny, and a large number of them mass 

 together to form a close-set, feathery, flat-topped clus- 

 ter. After the flowering season, a group of reddish- 

 brown seed-pods still marks the plant. The leaves are 

 oval in outline, with no teeth on the lower half and a 

 few large, sharply pointed ones above the middle. 



Thimbleberry (Bossekia). The thimbleberry, al- 

 so called false raspberry, is closely related to the com- 

 mon cultivated raspberry. It is not found to any ex- 

 tent on the park plateau, but is fairly abundant in the 

 shady ravines around Mammoth Hot Springs and at 

 similar elevations. The plant is a low, thornless shrub 

 with rather slender stems. The white flowers are 

 large and showy, somewhat resembling those of the 

 cultivated blackberry, and are borne either singly or a 

 few in a cluster. The fruits resemble red raspberries, 

 but are flatter in shape, rather soft and " mushy," and 

 not so acid. The leaves are larger than those of the 

 raspberry, but a little less deeply cleft.
