the petiole, i.e. the bundle from the petiole enters 

 between two successive bundles of the vascular ring. 



4. If axillary buds be present, note how their 

 bundle-system is inserted on the bundles of the main 

 axis, as well as on those entering from the petiole, This 

 point may be made clearer by a rough dissection of the 

 vascular system of an old axillary bud conducted in 

 the same way as the rough dissection of the leaf- trace 

 (see above, p. 56). Observe the large multicellular 

 hairs seated on the apex of small emergences as before 

 seen (p. 62).
