Trftiisdctions. 



the cortex consists of larger cells, with thinner walls and small intercellular 

 spaces between the cells. All the cortical cells contain chloroplasts. 



Above each group of phloem there is a wide oil-duct surrounded by 

 epithelial cells. The phloem elements are small, but the width of phloem 

 band is much greater than in A. filifolium. The xylem is divided into 

 2 parts : (1) next to the phloem there is a band of wood-fibres ; (2) a group 

 of 5-10 vessels with xylem parenchyma. 



The pith is composed of large thin-walled cells, but in the outer part 

 the cells are smaller, and their walls are thicker and are lignified.
