OSOSS ANATOMY OF FLOWERING PLANTS, xxiii 



With a very sharp knife split a bud from base to apex, and 

 notice the arrangement of the scales and young leaves (or youug 

 flowers) upon the little stem (axis). 



Cut a bud across (cross-section), and notice again the arrange- 

 ment of the parts. Notice particularly the manner of folding 

 {vernation) of the young leaves in the bud.

Types of Inflorescence, — In the study of the flowers of a plant 

 we must first consider their arrangement, i.e.. Inflorescence. 

 There are two principal kinds of inflorescence, the racemose and the 

 cymose. In the first the flowers are always lateral as to the prin- 

 cipal axis or axes of the flower-cluster; in the second, every axis, 

 principal and secondary, terminates with a flower. In either 

 arrangement each flower may be upon a flower-stalk (pedicel) of 

 greater or less length, or the stalk may be wanting, when the 

 flower is aesnle. In some cases of compound inflorescence the 

 branching is partly of one type and partly of the other ; such 

 cases may be considered examples of mixed inflorescence. 



Kinds of Inflorescence. — The most important of the forms com- 

 monly met are given in the following table of inflorescences : 



A. RACEMOSE OR BOTEYOSE INFLORESCENCES. 



I. Flowers solitary in the axils of the 



leaves — e.g., Vinca .... Solitary Axillaby. 



II. Flowers in simple groups. (Fig. XIX.) 

 1. Pedicellate. 



(a) On an elongated axis: pedicels about equal 



— e.g.. Mignonette Racbmb. 



(5) On a shorter axis; lower pedicels longer — 



e.g.. Hawthorn Corymb. 



(e) On a very short axis; pedicels about equal 



— e.g., Cherry Umbbl.
