6Si NOTKS ON nVliLIS aidAyTEA, LINDL. 



the leaf is occupied by a mass of large-celled pith (Hg. 11,;?.). 

 There are five fibro-vascular bundles, one small, and one larger, 

 in the angles of the side facing the stem, the smaller ones being 

 on the inside of the layer; at the outer angle of the leaf is one 

 bundle much larger than any of the others (fig. 11, i-.). The 

 bundles are inbedded in the pith, but have only a single row of 

 pith cells on their external aspect, and these cells are smaller 

 than the internal ones. Towards the base of the leaf there are 

 more than five bundles; the leaf has a nearly circular outline 

 there, and serial sections show the bundles widening out, so that 

 at the axil they form an incomplete ring. In the stem, the 

 bundles also form an incomplete ring. 



I think that the leaves are really branchlets which have taken 

 on the functions of the leaves.
