Question

Diadelphous $(9+1)$ stamens occur in

• A. Gramineae
• B. Cucurbitaceae
• C. Papilionatae
• D. Malvaceae

Answer 1

The correct option is C Papilionatae

The cohesion in a flower refers to the fusion of the same units of a whorl. When the stamens of the whorl androecium are fused with each other, either through the anthers or through the filaments, different appearances of stamens can be seen. One such condition is called adelphous in which the filaments are united and the anthers are free. When the filaments are united to form two bundles, one bundle of 9 stamens and the other with 1 stamen, it is called diadelphous condition (9 + 1). This is a feature of the family Papilionaceae.

Hence, the correct answer is 'Papilionaceae'
