MORPHOLOGY <)F 



sin-mounts: axillary and any other lateral leaf-buds are to be- 

 come branches. But even of buds which actually appeal a large 

 proportion do not grow. When a tenn'mal luid is formed (a> 

 Fin'. *1. *">. '-'I ). this is commonly the strongest, or among the 

 Stronger. But in many eases it habitually or eommonly fails to 

 appear. In the Elm (with leaves and therefore bud> alternate). 

 the bud axillary to the last leaf of the season takes its place. 

 In the common Lilac, a pair of buds, which were in the axils of 

 the uppermost of the (opposite) leaves, seem to replace the 

 terminal bud, which seldom develops. (Fig. G.) When all the 

 regular buds make their appearance, and the leaves are opposite, 

 the stem \\ill be crowned with the terminal bud, having an axil- 

 lary bud on each side of it. (Fig. 88.) 



7('.. Accessory IJuds. These are. as it were, multiplications of 

 the regular axillary bud. giving rise to two, three, or more, instead 



of one ; in some cases situated one above an* 

 other (superposed), in others placed side by 

 side (collateral). In the latter case, which 

 occurs occasionally in the Hawthorn, in cer- 

 tain Willows, in the Maples (Fig. 88), &c.. 

 the axillary bud seems to divide into three. 

 or itself to give rise to a lateral bud on each 

 side. On some shoots of the Tartarean 

 Honeysuckle (Fig. 90) from three to six buds 

 appear in each axil, one above another, tin- 

 lower being successively the stronger and 

 earlier produced ; and the one- immediately 

 in the axil, therefore, grows in preference : 

 occasionally two or more of them grow, and 

 superposed accessory branches result. It is 

 much the same in Aristoloehia Sipho, except 

 that the uppermost bud is there 1 strongest.
