Fabaceae or Papilionaceae is a large and economically important family of flowering plants. Vexillary aestivation is seen in members of Fabaceae. In vexillary aestivation, the outermost posterior petal is large which is known as the vexillum or standard, two lateral petals are known as the wings or alae, and the two anterior and innermost petals are united to form a boat-shaped structure known as the keel or carina. Hence, vexillum is found in Papilionaceae.

Arachis hypogea exhibits
-
Epicarpy
-
Apocarpy
-
Geocarpy
-
Syncarpy
Members of the genus Arachis exhibit geocarpy. This is a rare form of plant reproduction which involves the plant to plant its own seeds. After fertilization, the flower stalk elongates and bends towards the ground. Geocarpic plants like peanuts increase the opportunity of their offspring to survive long enough to germinate and grow.

Lathyrism is a neurological disorder in humans. It is caused due to consumption of legume belonging to genus Lathyrus, particularly Lathyrus sativus or Khesari dal. The cause of the disease is due to neurotoxin ODAP ($\beta$ - oxalyl,L $\alpha$ - diaminopropionic acid) which is structural analogue of neurotransmitter glutamate. Which results in paralysis of the lower limbs.
