Structurally, there are usually two flower forms (e.g. the ‘pin’ and ‘thrum’ forms of the primrose) which ensure that the pollen collected from the stamens of one type is deposited on the stigma of the other (see ENTOMOPHILY). There is also SELF-INCOMPATIBILITY between pollen and stigma from the same flower type, although there is compatibility between flowers of different types. Compare HOMOSTYLY. |
