layers. Flowers pink, in May. Grows from ten to twenty 

 feet high. 



P. prunifolia. Siberian Crab. This well-known species 

 is a native of Siberia. It is not only ornamental in flower, 

 but in fruit. There are two varieties, one with scarlet, the 

 other with yellow, fruit. The fruit is sometimes used as a 

 preserve, but it is more ornamental than useful. The tree 

 grows fifteen to twenty feet high ; in flower in May. Propa-

 foliage of both kinds is graceful, but this species is the most 

 delicate. The berries are more compact, and produced in 

 great profusion. These constitute the great ornament of the

 have : 



' Their spells were vain ; the hags returned 



To the queen in sorrowful mood, 



Crying that witches have no power 



Where there is Roan-tree wood.' 



She adds, ' This last line leads to the true reading of a linp
