Having the ovary free, but the petals and stamens borne on the calyx; -- said of flower such as that of the cherry or peach.
Perigynous ovaries have the flower parts (calyx, corolla, and androecium) attached to a hypanthium. The hypanthium is found only in dicots and is a fusion of the calyx, corolla, and androecium whorls forming a small cup-shaped structure that surrounds the ovary. The base of the hypanthium is typically attached to the receptacle as is the case with the members of the rose family (Rosaceae) and is therefore said to by hypogynous. The hypanthium can also be epigynous, that is, attached to the top of the ovary, as is the case with the fuschia flower. DIAGRAM: Ovary Position PHOTO
A type of flower structure in which sepals, petals and stamens appear to arise on the side of the ovary.
With perianth parts and stamens borne on an hypanthium that surrounds, but is not fused to, the superior ovary (Fig. 4.21).
a. (Gr. peri, around; gyne, female) growing in a ring around the pistil, as the stamens; having stamens, etc. growing in this way, said of a flower.
The perianth (sepals and petals) and androecium (male parts) are fused at the base so that the sepals, petals, and stamens appear to arise from the rim of a floral cup (the hypanthium). This condition is frequently found in plants of the rose family (Rosaceae).
other floral structures attached to extension of the receptacle which partially encloses ovary
a flower in which the receptacle forms a cup (hypanthium) surrounding, but not fused to the pistil and the stamens, petals and sepals are attached on the edge of the cup.
of perianth segments and stamens, arising from a cup or tube (hypanthium) that is free from the ovary but extending above its base. cf. epigynous, hypogynous.
