 from both edges towards 

 the midrib, — sometimes 

 inwards, when it is Invo-

 Violet and Water - Lily ; 

 sometimes outwards, when it is Revolule (Fig. 196), in the Rosemary and 

 Azalea. The figures are diagrams, representing sections through the leaf, 

 in the way they were represented by Linnseus. 



Section VIIL FLOWERS. 



196. Flowers are for the production of seed (16). Stems and brandies, 

 which for a time put forth leaves for vegetation, may at length put forth 

 flowers for reproduction. 



§ 1. POSITION AND ARRANGEMENT OF FLOWERS, OR INFLOR- 

 ESCENCE. 



197. Flower-buds appear just where leaf-buds appear; that is, they are 

 either terminal or axillary (47-49). Morphologically, flowers answer to 

 shoots or branches, and their parts to leaves. 



198. In the same species the flowers are usually from axillary buds only, 

 or from terminal buds only ; but in some they are both axillary and 

 terminal. 



199. Inflorescence, which is the name used by Linnseus to signify mode 

 of flower-arrangement, is accordingly of three classes : namely. Indeterminate, 

 when the flowers are in the axils of leaves, that is, are from axillary buds ; 

 Determinate, when they are from terminal buds, and so terminate a stem 

 or branch; and Mixed, wiicn these two are combined. 



200. Indeterminate Inflorescence (likewise, and for the same reason, 

 called indefinite inflorescence) is so named because, as the flowers all come 

 from axillary buds, the terminal bud may keep on growing and prolong the 

 stem indefinitely. This is so in Moneywort (Fig. 199),
