ROSE FAMILY. Rosaceae. 



The very small, narrow, toothless leaves are evergreen, 

 leathery and stiff, opposite, grayish in color and imper- 

 ceptibly downy, clustered in small separate bunches along 

 the rigid twigs, which are set almost at right angles to the 

 reddish-gray branches and rather swollen at the joints. 

 The whole shrub is from two feet to four feet high, stiff, 

 almost thorny, and rather forbidding in appearance, but 

 the odd little flowers are pretty. 



There are several kinds of Argentina, differing from 

 Potentilla in the leaflets and the style. 



This forms large straggling clumps of 

 Silver-weed many, pale, downy stems, lying on the 



Argentina ground and rooting at the joints, like 



Anserlna 



(Potentilla) strawberry runners, with handsome foliage 



Yellow and pretty flowers. The leaves are rich 



Spring, summer, green on the upper side and covered with 



autumn silky white down on the under, giving a 



North America, 



etc> silvery appearance, and the flowers are 



an inch or more across, bright yellow, 

 with centers of the same shade, and have long flower- 

 stalks, sometimes as much as a foot tall. This is common 

 and conspicuous in wet meadows and also grows in Europe 

 and Asia. 



There are only a few kinds of Dryas, shrubby plants, 

 living in cold and arctic regions. The Latin name means 

 "wood-nymph." 



This is a charming little plant, from 

 Alpine Avens 



Dryas ociopHala two to five inches tali, forming low, matted 

 White clumps of many branching stems, lying 



Summer O n the ground and woody at the base, and 



Northwest, etc. many st iffi s h leaves, with prominent veins, 

 dark green and smooth on the upper side and white with 

 close down on the under, their dark tones setting off the 

 pure-white flowers, which have downy flower-stalks and 

 are about an inch across, with about eight petals, a golden 

 center and the calyx covered with sticky hairs. The seed- 

 vessels are large and feathery. This grows in alpine places, 

 across the continent, reaching an altitude of fourteen 

 thousand feet, and in Europe and Asia.
