DICOTYLEDONS

fixed on the bark. They are growths of the skin (epidermis) 

 and differ in this respect from the spines of the Acacia, which 



are modified stipules, and 

 also from the axillary spines 

 of the Lemon tree, which are 

 modified branchlets. 



As in the Mango tree 

 the finer sorts of Roses are 

 grafted on the wild sorts by 

 budding, i. e., by inserting 

 the bud of a superior kind 

 under the bark of flie inferior (fig. 46). 



3. The Rose Leaves consist of a long middle rib with five 

 or seven leaflets, of which two are always opposite, the midrib 

 ending in a single 

 leaf. Such leaves 

 are called imparl- 

 pinnate, that is, un- 

 evenly pinnate (com- 

 pare it with a fea- 

 ther). At the base 

 of the leaf-stalk are 

 two stipules which in 

 young branches em- 

 brace a younger leaf; 

 between the stipules 

 of this, the next 

 younger again is 

 covered, and so on. 

 It? this manner the 

 inner, very tender 

 leaves are covered 

 by the outer ones by 



their sheathing stipules. The young leaflets are folded and laid 

 together like the leaves of a book. It may also be noticed that 

 the young leaves of some sorts of Roses are red coloured. (See 

 Mango, page 26.j
