these plants are not angiosperms.
there is no double fertilization in them.
endosperm is not formed in them.
endosperm gets used up by the developing embryo during seed development.
Calyx is the outermost whorl of the flower and are called sepals.
Sepals are green, leaf like and protect the flower in the bud stage.
The calyx may be gamosepalous (sepals free) or polysepalous (sepals united).

Imbricate aestivation is found in papilionaceous family.
Generally sepals are green, leaf like and protect the flowers in the bud stage.
In cymose type of inflorescence, the main axis terminates in a flower, hence is limitless in growth.
In axile placentation ovary is one chambered but it becomes two cambered due to formation of the false septum.
