  2. Gynoecium - Wikipedia

    en.wikipedia.org/wiki/Gynoecium

    If the hypanthium is absent, the flower is hypogynous, and the stamens, petals, and sepals are all attached to the receptacle below the gynoecium. Hypogynous flowers are often referred to as having a superior ovary. This is the typical arrangement in most flowers. If the hypanthium is present up to the base of the style(s), the flower is ...

  3. Ovary (botany) - Wikipedia

    en.wikipedia.org/wiki/Ovary_(botany)

    A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm.Because gymnosperms do not have an ovary but reproduce through fertilization of unprotected ovules, they produce naked seeds that do not have a surrounding fruit, this meaning that juniper and yew "berries" are not fruits, but modified cones.

  4. Floral morphology - Wikipedia

    en.wikipedia.org/wiki/Floral_morphology

    Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.

  5. Plant reproductive morphology - Wikipedia

    en.wikipedia.org/wiki/Plant_reproductive_morphology

    Close-up of a Schlumbergera flower, showing part of the gynoecium (specifically the stigma and part of the style) and the stamens that surround it. Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.

  6. Quinoa - Wikipedia

    en.wikipedia.org/wiki/Quinoa

    A perfect flower has five sepals, five anthers and a superior ovary, from which two to three stigmatic branches emerge. [15] The green hypogynous flowers have a simple perianth and are generally self-fertilizing, [14] [16] though cross-pollination occurs. [17]

  7. Glossary of plant morphology - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_plant_morphology

    In some flowers, a tube or cup-like hypanthium (floral tube) is formed above or around the ovary and bears the sepals, petals, and stamens. There may also be a nectary producing nectar. Nectaries may develop on or in the perianth, receptacle, androecium (stamens), or gynoecium. In some flowers nectar may be produced on nectariferous disks.

  8. Proteaceae - Wikipedia

    en.wikipedia.org/wiki/Proteaceae

    In many genera, the most obvious feature is the large and often very showy inflorescences, consisting of many small flowers densely packed into a compact head or spike. This character does not occur in all Proteaceae, however; Adenanthos species, for example, have solitary flowers. In most Proteaceae species, the pollination mechanism is highly ...

  9. Receptacle (botany) - Wikipedia

    en.wikipedia.org/wiki/Receptacle_(botany)

    The receptacle (grey) in relation to the ovary (red) in three types of flowers: hypogynous (I), perigynous (II), and epigynous (III) In angiosperms, the receptacle or torus (an older term is thalamus, as in Thalamiflorae) is the thickened part of a stem (pedicel) from which the flower organs grow.
