 the axih while tin- hnver juul smaller ones coinnionly do not grow at 

 all. In other eases the tln-ee buds stand side by sid«^ 

 in the axil, as in the Ilawtliorn, and tiie Red Alapln 

 (Fig. i)3). It" these were all to grow into hranches. 

 they would .stifle or jostle each other. lint some 

 of them are commonly flower-hiids : in 

 the Red Maple, only the middle one is 

 a leaf-i)ud, and it does not grow until 

 afier those on each side of it have ex- 

 panded the blossoms they contain. 



GO. Sorts of Buds. It may be useful 

 to enumerate the kinds of buds which 

 have now been mentioned, referring 

 l).iclc to the paragraphs in which the pe- 

 culiarities of each are explained. Buds, 

 then, are either termhial or lateral. 

 Tiiey are 



Terminal when they rest on the apex 

 of a stem (42). The earliest terminal 

 bml is \\\o. plumule of the embryo (10). 



Lateral, when they appear on the 

 side of a stem : — of which the only 

 regular kind is the 

 Axillary (4o), namely, those which are situated in 

 the axils of leaves. 



Accessory or Supernumerary (.OO), when two or more 

 occur in addition to the ordinary axillary bud. 53 



Adventitious {'>^). wIkmi they occur out of the axils and without 

 order, on stems or roots, or even on leaves. Any of these kind* 

 may be, either 



Naked, when without coverings; or scaly, when protected by 

 scales (44, 4."»). 



Latent, when they survive long without growing, and eonnnonly 

 without being visible externally (-"i"). 



I^af-huds, \\\\v\\ they cmilain leaves, ami develop into a leaty 

 shoot. 



Fluwer-buds, when they contain l)lossoms. and no leaves, as the
