THK FLOWEU. 



a whole blossom into foliaceous parts has been termed chlorosis, from 

 the green color thus assumed. 



431. A somewhat different proof that the blossom is a sort of 

 branch, and its parts leaves, is occasionally furnished by monstrous 

 flowers in the production of a leafy branch from the centre of a flower, 

 or of one flower out of the centre of another (as rose-buds out of 

 roses). Here the receptacle or axis of the flower resumes the 



ordinary vegetative 

 growth, as in Fig. 

 349, 350. In wet 

 and warm springs, 

 some of the flower- 

 buds of the Pear and 

 Apple are occasion- 

 ally forced into vege- 

 tation, so as com- 

 pletely to break up 

 the flower and change 

 it into an ordinary 

 leafy branch. This 

 proves that the recep- 

 tacle of a flower is of the nature of the stem. 



43"2. An analogous kind of monstrosity, viz. 

 the development of buds — either into leafy 

 branches or into blossoms (Fig. 351) — in the 

 axils of petals, or even of stamens or pistils, fur- ^™ 



nishes additional evidence that these bodies are of the nature of 

 leaves ; for, whatever bears a bud or 

 branch in its axil must represent a leaf 



433. The irresistible conclusion from 

 all such evidence is, that the flower is 

 one of the forms — the ultimate form — 

 under which branclies appear ; that the 

 leaves of the stem, the leaves or petals 

 of the flower, and even the stamens 

 and pistils, are all forms of a common
