What's the difference between corolla and perianth?

Corolla


Definition:

  • (n.) The inner envelope of a flower; the part which surrounds the organs of fructification, consisting of one or more leaves, called petals. It is usually distinguished from the calyx by the fineness of its texture and the gayness of its colors. See the Note under Blossom.

Perianth


Definition:

  • (n.) The leaves of a flower generally, especially when the calyx and corolla are not readily distinguished.
  • (n.) A saclike involucre which incloses the young fruit in most hepatic mosses. See Illust. of Hepatica.

Example Sentences:

  • (1) In contrast, mutations in another floral homeotic gene, APETALA2 (AP2), result in the replacement of the perianth organs by the reproductive organs.
  • (2) In ag mutants, the loss of AG function leads to the conversion of these organs to the perianth organs (petals and sepals).
  • (3) The proper time to pick the flower buds comes when they are fully developed before the perianth appears.
