A CHAPTER TO STUDY. 



An Umbel is like a corymb, only the pedicels branch from 

 the same central point, suggesting the ribs of an umbrella. It 

 may be simple, or compound. (Fig. 9.) 



A Cyme is a flat-topped inflorescence, differing from an 

 umbel in that its innermost flowers are the first to open. (Fig. 



10.) 



A Complete flower is one that is provided with the essential 

 organs of reproduction, the stamens and pistil ; and the pro- 

 tecting organs, the calyx and corolla. As an example of a 

 complete or typical flower we may take the one illustrated in 

 Fig. II and 12.

The Calyx is the lower, outer set of leaves at the base of 

 the flower which rests upon the receptacle, or end of the flower- 

 stalk. It is usually green, but not always. At times we find it 

 brilliantly coloured and conspicuous. (See Fig. 12.) 



The Sepals are the leaves of the calyx when it is divided to 

 the base. 



The Calyx is gamosepalous when the sepals are wholly or 

 partly grown together. 



The Corolla is the next inner and upper set of leaves. It 

 is the alluring part of the flower, and attracts the bees and but- 

 terflies to its whereabouts that its pollen maybe carried through 

 their agency. (Fig. 12.) 



The Petals are the leaves of the corolla when it is divided 

 to the base. 



The Corolla is said to be gamopetalous when the petals 

 are wholly or partly grown together.
