Stigma is the receptacle part of the carpel ,which is the female floral whorl. During the process of fertilisation, pollen grains get deposited on the stigma. A long and feathery stigma is generally found in flowers pollinated by wind. Their feathery nature helps in trapping pollen grains transported by wind.
