Figure 216. — Transverse section through a branchlet and two clusters of 

 imbricate leaver. In the/lower the central axis is seen to 

 be oval io shape with its bundles composed of ::^yiem (red) 

 and narrow phloem (blue), the whole surrounded by endoder- 

 raal cells which also run i nto the two adnate leaves — with an 

 oil ca^■ity in each. A bundle cut obliquely is seen on the in- 

 ner side of the left oil cavity. The nucleated character of the 

 cells is a feature of the leaves. The top half is a cluster of 

 younger leaves. Stained with hjematoxylin and safranin.
