Bush Cinquefoil (Potentilla jruticosa 

 L.), fig. 42. — Low, widely-branching shrub, 1/2 

 to 4 feet high; leaves mostly 1/2 to 1 inch long, 

 white-silky below, divided into 3 to 5 smaller, 

 oblong leaflets; flowers i/4 to 1 inch across, 

 petals 5, bright yellow; fruits tiny seed-like 

 achenes. (Syn. Dasiphora jruticosa Rydb.) 



Bush cinquefoil is widely distributed in the 

 northern hemisphere, occurring in Europe, 

 Asia, and over most of the northern and 

 mountainous parts of North America. It is a 

 very attractive shrub with bright yellow, but- 

 tetcup-like flowers, growing typically in moist rocky subalpine meadows, 

 or sometimes on dry slopes or in open forests. The bushes may be low 

 and sprawling, or erect and becoming as much as 4 feet in height. The 

 flowering period e.xtends over a long time, often from early spring until 

 late summer. The leaves, although rather coarse in te.xture and with an 

 astringent taste, are abundant and of good size and are eaten to a certain 

 extent by deer and elk.

Blackberry, Raspberry (Rubus L.) 



Blackberries and raspberries are among the best known and most easily 

 recognized of the wild shrubs because many of them so closely resemble the 

 cultivated varieties. The familiar fruits are composed of tiny 1 -seeded berries 

 or drupelets which form a single layer around a central core or receptacle. 

 Blackberries fall from the stems in the form of solid berries with the drupe- 

 lets remaining attached to the central core, while the raspberries separate from 

 the receptacles as hollow or cup-shaped berries. Fruits of many of the species 

 are gathered extensively for canning and preserving.
