ROSACES 309 



Rosaceae 



This important order includes herbaceous plants, trees 

 and shrubs; not the least of its interest lies in the number 

 of fruits furnished by it apples, pears, plums, rasp- 

 berries, strawberries and others. The alternately arranged 

 leaves are either simple or composite and, except in the 

 case of Spiraea Jlruncus, accompanied by stipules ; the 

 flowers are regular, the calyx, which is persistent, com- 

 posed of four to five divisions, often associated with an 

 involucre of bracts alternating with the sepals, which are 

 equal in number to the petals; the stamens vary in number 

 and, like the petals, are inserted on the calyx; the fruit 

 consists of carpels, either free or adnate. 



Dryas 



"Eng.: Mountain Avcns; Fr. ; Dryade ; Ger. : Silberwiirz. 



Beautiful prostrate alpines which do well anywhere 

 in rockeries, old walls, sunny slopes and borders, where 

 a light, cool, pebbly soil and fair amount of sun can be 

 given. Deep rooting room must be given and it is almost 

 useless to remove established plants, which if left alone 

 will make large patches. Young plants may be divided in 

 spring, but seed is the only way though slow of raising 

 a new stock. Limestone in desirable. A popular name is 

 The Suisse, in the composition of which it plays a great 

 part; the country folk frequently make a pleasant astrin- 

 gent or digestive from the glossy leaves by infusion.
