closely fused together, and their partitions have broken 

 away, leaving a central ovuliferous column. The 

 stamens are five, and they have grown fast to the corolla 

 tube. The sepals are five, and they have united with one 

 another for some distance from their bases.

557. The Phlox (Phlox ) again reminds one of the pinks, 

 and primroses, to which it is related. The corolla 

 is gamopetalous, and the five stamens are attached 

 to the corolla tube. The five sepals are united for some 

 distance from their bases (gamosepalous). The pistil 

 is reduced to three carpels, but here the carpel cavities 

 persist, and in each there are from one to four ovules. 



558. In the Petunia (Petunia) the gamopetalous 

 corolla is more widely open, while the attachment of the 

 five stamens, and the gamosepaly of the calj^x are 

 like those of phloxes and primroses. The reduction in 



the number of carpels has continued so 

 that here there are only two, each with 

 its many-ovuled cavity. 



559. The Snapdragon (Antirrhinum) has 

 intensified the slight irregularity of the 

 corolla of the Petunia so that it is markedly 

 2-lipped. Its stamens which are attached 

 to the corolla are reduced to four, one hav- 

 ing disappeared. The pistil is bicarpellary, and the seeds 

 many in each carpel cavity. The calyx is gamosepalous. 

 560. The Sage (Salvia) carries the preceding modifi- 

 cations a step further. The gamopetalous corolla is
