PROPAGATION OP PLANTS. 



forms, are generally, in the higher order of plants, com- 

 posed of imbricated scales, enclosing the rudiments of 

 stems, leaves, or organs of reproduction. The ter- 

 minal bud is situated on the end of a stem or branch (as 

 in fig. 10), and the axillary bud on the side just below, 

 and usually in the axils of the leaves, and this bud may 

 either grow and become a branch or remain dormant, or 

 be entirely overgrown and obliterated. The terminal 

 and the axillary buds are really the same in 

 structure and importance, for if the terminal 

 bud be destroyed, the one next below it be- 

 comes the terminal, and the elongation 'of 

 the stem or branch proceeds with but a slight 

 check. It is seldom that all of the axillary 

 buds become branches, as only the strongest 

 and most favorably situated grow, for nature, 

 in her prodigality, provides more than are 

 required in the regular order of growth. 

 The accessory bud is merely one of a cluster 

 of buds sometimes surrounding the base of 

 Fiff. 10. a terminal, but more frequently accompany- 

 ''^^tl^^°mg the axillary buds. H by accident or 

 BDDs. otherwise the regular terminal or axillary 

 bud is destroyed, the accessory buds take their place, 

 one or more of their number growing. These ac- 

 cessory buds are not only found on the stems of 

 annual and perennial plants, both herbaceous and 

 ligneous, but also scattered over the surface of such 

 tubers as the common Potato and Jerusalem Artichoke. 

 In other tubers and bulbs they are found clustered at 

 the crown or apex, as in the tubers of the Dahlia, Herba- 

 ceous Pseony and bulbs like the Turnip, Beet, Crocus and 

 Gladiolus. Then, again, we find the axillary and acces- 

 sory buds distributed along subterranean stems of various 

 kinds of plants, and naturally they are only produced at 

 the nodes or joints, as seen on the cane of the Grape-vine
