- n. collective term for the outer parts of a flower consisting of the calyx and corolla and enclosing the stamens and pistils
In the female flower the perianth is the same as in the former, the stamens sterile.
Applied to a perianth, which is tough, thin, and femi-tranfparent; as in Statice Armaria, or Thrift, Centaurea glaf -
Many of the recorded instances of so-called metamorphosis of the parts of the flower to sepals have occurred in monocotyledonous plants, or others in which the calyx and corolla are of the same colour, and constitute what is frequently termed the perianth; and as this is usually brightly coloured (not green) it is more convenient to group the metamorphoses in question under the general term Petalody, which thus includes all those cases in which the organs of the flower appear in the form of coloured petal-like organs, whether they be true petals or segments of a coloured perianth.
B, The "perianth" with the small perichaetial leaves below it.
To these leaves surrounding the sporophylls, the general name of "perianth" or
The segments of the perianth also closed on the pistil, but more slowly than the stamens.
Bud angled, perianth lobes joined, fleshy with a red surface.
Remarks: The other member of this genus in Kenya, H. africana, is different in that it has no hairs at the edge of the perianth lobes.
This crown is connected at the base of the divisions of the perianth, which divisions do not go to the base of the flower, but form what may be called an outer tube.
In the scilla there is no corona, neither a tube, but the petal-like sepals or divisions of the perianth are entire, going to the base of the flower.
