perigynous

The androecium has 2 stamens inserted in the perigynous zone and alternate with the lobes.

Such flowers are termed perigynous or half-epigynous.

The hypanthium are well-developed, resembling calyx tube tepals and the stamens perigynous.

Perigynous flowers are often referred to as having a half-inferior ovary (or, sometimes, partially inferior or half-superior).

The flower is perigynous (sepals, petals and stamens around the edge of the ovary) the ovary is superior.

(Fusion of sepals, petals and stamen fused in a tube) Prunus rivularis is defined as a perigynous plant.

In these flowers, the ovary is physically lower than the lobes of the sepals and petals and below the point of attachment of the stamen filaments - the ovary is still considered to be superior but the flower is termed perigynous.
