What type of placentation is seen in Liliaceae?
Axile placentation: When the placenta is axial and the ovules are attached to it in a multilocular ovary, the placentaion is said to be axile. It is found in multicarpellary syncarpous gynoecium. This type of placentation is seen in Solanaceae and Liliaceae families.

In basal placentation, the placenta develops at the base of ovary and a single ovule is attached to it.
