 glow into branches, just as the first or tenuinal bud of tlie seedling arrows to 

 .make the main stem 



5»;. The Arrangement of Branches, therefore, follows that of the axillary butls, and 

 this Uiat of tiie leaves. 

 Ndw leaves are plnced 

 on the stem in two 

 principiil ways; they 

 are either aU'-niatc or 

 rippoxHt'. 1'liey are al- 

 h rrtafc when they fol- 

 low one after another, 

 there hcinf; only one 

 to each joint of the 

 stem, as in Morninjr- 

 Glory (Fig. .4, all after 

 the seeddea\es), and 

 in the Linden or ]3ass- 

 wood (Fig. 52), as well 

 as the greater part of 

 trees or ])lants. They 



are opposite when there are two leaves upon each joint of stem, as in TTorse-chest- 

 nut, T.ilac, and Ma[)le (Fig. 3r, 53) ; one leaf in such ca.ses being always exactly 

 on theojiposite side of the stem from its fellow. Now in the axil of almost every 

 leaf of these trees a bud is soon formed, and in general plainly shows itself befoio 

 summer is over. In Fig. 52, a, a, a, a, are the (txilltu'tf hiuJn on a twig of FJass- 

 W(»od tliev are alft'n/((f«/, like the leaves — and / is the lerminal hmf. Fig. 53, 

 a twig of lied Maple, has its axillary buds oj>prn<ifp, like the leaves; and on the 

 very summit is the tmititial InuL Next spring or sooner, the ft)rmer grow into al- 

 ii.ruafe Iii'i(>»rl>"t( : the latter grow into o]>pos/tr hrnwhr.^. These branches in their 

 Pturn form l'.<i.~ in the axils of their leaves, to grow in time into a new gener, > \ 

 of similar urjinches, and so on, year after year. So the reason is plain wh^ iG 

 branching or spray of one tree or bush differs from that of another, each having 

 its own plan, depending upon tl'e way the leaves are arranged on the stem.
