THE HELIOTROPE FAMILY. 209 



peculiar in being scarious and petaloid, i.e. coloured 

 like a corolla. The petals, unlike those of Phimha'go, 

 are generally quite free or polypetalous, when the 

 stamens are epipetalous in being adherent to the claws 

 of the petals. 



Many species are cultivated on account of their 

 brightly coloured calyx, and though the flowers are 

 small, they are massed together in clusters.
