 Fig. 4. Ditto of capitulum. 

 Fig. 5. Cellular tissue of surface of peduncle. 

 Fig. 6. Transverse, and fig. 7. vertical sections of cellular tissue at the circumference of peduncle, where 



there is a little deposit of wax. 

 Fig. 8. Cellular tissue of young peduncle, the cells each with a globule of wax. 

 Fig. 9. A single cell detached, showing its dotted walls and wax-globule with its nucel. ' 



Fig. 10. Another cell more advanced, with the wax-secreting cell burst and its contents discharged in 



the cavity of the cell.

 Fig. 12. Cellular tissue of rhizome. 

 Fig. 13. A single cell from the same. 



Fig. 14. Transverse section of portion of peduncle and vascular bundle. 



Fig. 15. Vertical section of the same, showing the vascular bundle to consist of simple delicate tubes. 

 Fig. 16. Cuticle of rhizome with empty bladdery cells that give it a granular appearance.

 Fig. 21. Transverse, and fig. 22. vertical sections parallel to the radius of a portion of the rhizome, 



showing the termination of the vascular system. 

 Fig. 23. Very highly magnified view of longitudinal section of a vascular cord and its surrounding 



tissues ; it consists of barred tubes, a, enclosed in a cellular tissue whose cells are filled with 



viscous fluid, b: at c, some of the cellular tissue of the rhizome is seen containing wax-deposits.
