Perianth

 

in the flowers of angiosperms, the modified bracts that surround the stamens and pistils. Simple perianths are composed of bracts of the same color. Tulips, lilies, buckwheat, beets, and goosefoot have simple perianths. Perianths with small, usually green calyxes and larger, variously colored coronas are said to be double. Such perianths characterize wild roses, crowfoot, and bellflowers.


Perianth

 

(1) A covering surrounding the generative organs of angiospermous plants.
