• Label: Ovary position
• Entity URI: https://w3id.org/APD/traits/trait_0012444
• Type: categorical
• Definition: A floral organ morphology trait [TO:0000862] which is the position [PATO:0000140] of the plant ovary [PO:0009072] relative to the other flower [PO:0009046] organs [PO:0009008], in particular whether the ovary is attached above or below the perianth [PO:0009058] organs (the petals [PO:0009032] and sepals [PO:0009031]).;The position of the flower ovary relative to the insertion level of the remaining floral organs.
• Additional comments: The ovary is the part of the gynoecium where the ovules are produced. The ovary may be located on the receptacle and thus be positioned above the insertion level of the remaining floral organs (i.e., the ovary is superior and the flower is hypogynous). Alternatively, the ovary may be embedded in the receptacle and therefore be located below the insertion level of the remaining floral organs (i.e., the ovary is inferior and the flower is epigynous). Flowers with a hypanthium may either have a superior ovary (perigyny; e.g., many Rosaceae) or an inferior ovary (epiperigyny). It is also possible that the ovary is inferior to a certain degree only, such as half-inferior, if the receptacle is surrounding the ovary to its mid-level. Definition and trait values derived from Schoenenberger et al. (2020) for their character '102. Ovary position (D1)'
• Allowed values:

  value	description
  half_inferior	Flower where the receptacle is surrounded by the ovary to its mid-level.
  inferior	Flower with inferior ovary, where the ovary is embedded in the receptacle and therefore located below the insertion level of the remaining floral organs.
  one_quarter_inferior	Flower where the receptacle surrounds up to one quarter of the ovary.
  superior	Flower with superior ovary, where the ovary is positioned above the insertion level of the remaining floral organs.
  three_quarters_inferior	Flower where the receptacle surrounds more than three quarters of the ovary.
