lateral branches modified for reproduction. The bundles which make up the woody 

 cylinder of the peduncle take their origin directly on several different wedges of 

 the woody cylinder of the trunk itself, and then pass obliquely upward and outward 

 through the cortical parenchyma. In the longitudinal section of fruit VI, as may 

 be seen in photograph 1, plate xxxix, both the lower and upper segments of the 

 peduncular bundle supply are unbroken in their entire course through the cortex 

 to their origin on the wedges of the woody cylinder of the trunk, and no connec- 

 tion with or appression to similar bundles of an axillary leaf base appears. In the 



similar section of axis IV, photograph 1, plate xi.i, 

 the course of both segments of the bundle supply 

 is not so direct, but is nevertheless nearly com- 

 plete, and simply shows, were this not perfectly 

 clear in transverse sections, that the different 

 strands which finally take a cylindrical form in 

 the base of the peduncle curl or curve about in 

 places in their course through the cortex. In 

 the latter section the axillary leaf base and its 

 bundle supply are also quite distinct, although 

 no direct connection with the peduncle trace is 

 evident. But aduate growth between the ped- 

 uncular and axillary leaf-base supply might be 

 present at some point outside the plane of the 

 sections made, or might form later on. The 

 tracing of the entire course of all the segments 

 or parts of a peduncular bundle supply from their 

 origin has not been attempted in the case of the 

 present trunk, though clearly there is a quite 

 direct course of all the parts of each peduncle 

 supply from a series of nearly adjacent woody 

 wedges of the trunk. The general appearance 

 in transverse section is, however, beautifully 

 shown in figure 96, where two nearly superim- 

 posed peduncular supplies (fruit viii) are cut — 

 the one just beneath and the other well within 

 the cortex. In the upper peduncle the bundles 

 , of the axillary leaf base are distinct, but not in the

 presumably, although not certainly, foliar. Even in the absence of further sec- 

 tions it may, however, be seen from such clear testimony that the several elements 

 of a given peduncular bundle series which unite to form a sub-cylindrical or com- 

 pressed pattern as the} - take their course through the cortex of the trunk must
