CHAPTER V. 



EXAMINATION OF COMMON PLANTS, CONTINU ED AS BEFORE. 



1. Colocasia. 



2. Dendrobe. 



3. Crinum. 



4. Dracaena. 



5. Wheat. 



6. Points of agreement in the four plants just examined. The 



structure and venation of their leaves, and the number of parts 

 in the flowers. 



7. A grain of Wheat is examined. Parts of the seed. 



8. Structure of the embryo of Wheat. There is but one cotyledon. 



It is therefore monocotyledonous. Its mode of germination. 



9. General characters of Monocotyledons. 



10. Tabular review of Dicotyledons and Monocotyledons. 



1 1. These gieat Classes are divided into subordinate groups. 



12. The principal divisions of Dicotyledons, and the characters upon 



which they depend. 



13. And of Monocotyledons. 



14. The Classes, Sub-classes, and Divisions are tabulated. 



I. Colocasia antiquorum (known as Kuchoo, Kachaiu, 

 Ghwian, or Kandalla). — Without much care you will be 

 liable to misunderstand the structure of this plant, as did 

 Linnaeus himself that of a near European ally. The flowers 

 are closely packed in rings upon the lower part of the 

 fleshy spike, which you find enclosed in a large sheathing
