(The Kew Plant Glossary (2nd Edition))
(The Kew Plant Glossary (2nd Edition))
Ovary superior
‘When the sepals, petals and stamens are inserted below the ovary‘
‘When the receptacle bearing the calyx, corolla and stamens is expanded into a (free) hypanthium‘
(The Kew Plant Glossary (2nd Edition))
‘When the receptacle bearing the calyx, corolla and stamens is expanded into a (free) hypanthium‘
(The Kew Plant Glossary (2nd Edition))
Ovary inferior
‘An ovary that has the calyx above it‘
(The Kew Plant Glossary (2nd Edition))
(The Kew Plant Glossary (2nd Edition))
Ovary half-inferior
‘An ovary that is ‘partly below and partly above the level of attachment of the perianth and stamen; partially embedded in, or surrounded by, the receptacle‘
(The Kew Plant Glossary (2nd Edition))
(The Kew Plant Glossary (2nd Edition))
Flower hypogynous
‘The sepals, petals and stamens inserted on the receptacle below and free from the ovary, the ovary thus being superior‘
(The Kew Plant Glossary (2nd Edition))
(The Kew Plant Glossary (2nd Edition))
Flower perigynous
‘When the sepals, petals and stamens are carried up around the ovary on a hypanthium‘
(The Kew Plant Glossary (2nd Edition))
(The Kew Plant Glossary (2nd Edition))
Flower epigynous
‘In epigynous flowers, the hypanthium is fused to the gynoecium, and the free parts of the sepals, petals, and stamens appear to be attached to the top of the gynoecium.‘
