Diagram showing the stigma-style-ovary system of the female reproductive organ of a plant. The stigma is fixed to the apex of the style, a narrow upward extension of the ovary. The stigma ( pl.: stigmas or stigmata) [1] is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower .

stigma. 1. The receptive tip of the carpel, which receives pollen at pollination and on which the pollen grain germinates. The stigma is adapted to catch and trap pollen, either by combing pollen off visiting insects or by various hairs, flaps, or sculpturings. The stigmas of certain plants show haptotropic movements.

The stigma itself forms the distal portion of the style, or stylodia, and is composed of stigmatic papillae, the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface.
The stigma is the receptive tip of the carpel(s), which receives pollen at pollination and on which the pollen grain germinates. The stigma is adapted to catch and trap pollen, either by combining pollen of visiting insects or by various hairs, flaps, or sculpturings.
The stigma sits at the apex of the column in the front but is pointing downwards after resupination (the rotation by 180 degrees before unfolding of the flower). [ citation needed ] This stigma has the form of a small bowl, the clinandrium , a viscous surface embedding the (generally) single anther.
