STELLATE TISSUE. 33 



ordinary rush or reed, which are very slight in diameter in 

 comparison with their length, and in which the cells are still 

 further strengthened and lightened by the projection of their 

 sides into a number of points which meet each other, and 

 leave interstices between them. This modification of the 

 cellular system is called " Stellate " (or star-like) Tissue, and 

 two examples of it are given in the illustration, one being 

 taken from the common rush, and the other from the seed- 

 coat of the privet. A very good specimen of stellate tissue 

 may be obtained by cutting a thin section of the white inner 

 peel of the orange.
