    Study Notes

    Complete and Incomplete Flowers

    • A complete flower has all four sets of floral leaves: sepals, petals, stamens, and carpels attached to the receptacle.
    • An incomplete flower lacks one or more of these sets.

    Perfect and Imperfect Flowers

    • Unisexual flowers are either staminate (stamen-bearing) or pistillate (pistil-bearing) and are imperfect.
    • Bisexual flowers are perfect or hermaphroditic.
    • Monoecious plants have staminate and pistillate flowers on the same individual plant.
    • Dioecious plants have staminate and pistillate flowers on separate individual plants.

    Whorled and Spiral Arrangements

    • In most flowers, sepals, petals, stamens, and carpels are arranged in whorls or circles on the axis of the flower.
    • In some flowers, one or more sets of flower parts are arranged in spirals.

    Floral Symmetry

    • Regular flowers have petals of similar shape that radiate from the center of the flower and are equidistant from each other.
    • Irregular flowers have petals that are dissimilar, do not radiate from the center, or are not equidistant from each other.

    Union of Flower Parts

    • In some flowers, parts of a whorl are united, a condition known as coalescence or connation.
    • Synsepaly refers to the union of sepals along their edges.
    • Sympetaly refers to the union of petals.
    • Synandry refers to the union of stamens.
    • Syncarpy refers to the union of carpels.
    • Adnation refers to the union of parts of different whorls.

    Elevation of Flower Parts

    • In some flowers, the receptacle is convex or conical, and the flower parts are arranged one above another.
    • The arrangement of flower parts in this order: sepals, petals, stamens, and carpels.
    • An ovary positioned above the points of origin of the perianth parts and androecium is superior.
    • An ovary positioned below the points of origin of the perianth parts and androecium is inferior.
