Question : Distinguish between families Fabaceae, Solanaceae and Lilia

1.	Question : Distinguish between families Fabaceae, Solanaceae and Liliaceae on the basis of gynoecium features.
Answer» Solution :In Fabaceae : The gynoecium is monocarpellary with a superior or partly INFERIOR unilocular OVARY. The ovules are many on the ventral suture and the placentation is marginal. The style is SIMPLE and the stigma is capitate. In Solanaceae : The gynoecium is bicarpellary and syncarpous with a superior and bilocular ovary. There are many ovules in each locule and the placentation is axile. The family is characterized by the presence of swollen placentae and obliquely placed septum in the ovary. In Liliaceae : The gynoecium is TRICARPELLARY and syncarpous with a superior and trilocular ovary. There are numerous ovules in each locule and the placentation is axile. Style is either simple with three distinct or a trilobed stigma. USUALLY a nectary is present on each septum.
