Question

The most highly evolved and perfect type of inflorescence is

• A. hypanthodium
• B. spadix
• C. capitulum
• D. polychasial cyme

Answer 1

The correct option is C capitulum

Capitulum (flower head) is a racemose inflorescence with the axis flattened to form a disk. The flowers are sessile with the oldest outside, and enclosed in an involucre of bracts, e.g., sunflower, marigold. The advantages of capitulum are -
(i) a single insect can pollinate numerous florets.
(ii) compactness of flowers make the condition more attractive, hence much more chances of pollination.
