Question

Bipinnate leaves and spiny stipules are the characteristics of family

• A. Papilionaceae
• B. Cesalpinoideae
• C. Mimosoideae
• D. Malvaceae

Answer 1

The correct option is C Mimosoideae

Bipinnate leaf is characterised by a presence of secondary rachii on the long main rachis (primary rachis). The secondary rachii bears pinnately arranged leaflets, thereby making it double pinnate, hence, the name is bipinnate.
Papilionaceae has simple or pinnate or palmately compound, nonspiny stipulate leaves.
Cesalpinoideae has simple or pinnate or palmately compound, nonspiny stipulate leaves.
Mimosoideae has simple or bipinnate or palmately compound, stipulate leaves. Stipules are spiny and hollow inside that provide shelter to ants. Malvaceae has simple or palmately compound, non spiny stipulate leaves.
Therefore, the correct answer is option C.
