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 calyx 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.

to the corolla are reduced to four, one hay-

many in each carpel cavity. The calyx is gamosepalous.

cations a step further. The gamopetalous corolla is
