Question

One of these bears coma for anemochory?

• A. Cinchona
• B. Calotropis
• C. Alstonia
• D. Both (B) and (C)

Answer 1

The correct option is D Both (B) and (C)

Anemochory is defined as seed dispersal by wind. Common dispersal syndromes of anemochory are wing structures and brown or dull coloured seeds without further rewards. Anemochory is commonly found in open habitats, canopy trees and dry season deciduous forests. Anemochory is facilitated by coma in Calotropis and Alstonia.
In Calotropis and Alstonia, a tuft of hair called as plume or coma develops as a crown of seeds. Cinchona anemochory is by wings and not by coma.
Therefore, the correct answer is option D.
