 opposite, entire leaves, interpetiolar stipules, and terminal 

 dense clusters of bright scarlet flowers. 



Fig. 140. Vertical section of flower of Ixora. 



As Sub-types, note — 



Gardenia florida of gardens, with one-celled ovary and 

 numerous seeds ; and 



Rubia cordifoUa^ Munjeet or Indian Madder, with four 

 leaves in a whorl (two smaller), a two-celled ovary, and one 

 seed in each cell. 



The Gardenia is often " double," from a multiplication of 

 the cohering petals and change of stamens into petals. 

 This "doubling" of flowers is much more frequent among 

 polypetalous than amongst gamopetalous FamiHes. It is 

 generally due both to transformation of the stamens into 

 petals and to actual increase in number of parts. 



The species of this large Family, excepting those of the 

 Sub-type represented by the Munjeet with whorled leaves,
