Explanation:
The stigma of anemophilous flowers is always rough and sticky to increase the ability to capture pollen.

Features of wind pollination syndrome include a lack of scent production, a lack of showy floral parts, reduced proportion of nectar, production of enormous numbers of pollen grains.
This distinguishes them from entomophilous and zoophilous species.
