Liliaceae Family

Tepals

Liliaceae flowers have:

  • 3 (Calyx) sepals and 3 (corolla) petals that look alike and are often called tepals
  • 6 stamens - Androecium
  • Gynoecium: a single pistil with a superior ovary of 3 fused carpels

They are usually actinomorphic or radially symmetic, not so frequently zygomorphic or bilaterally symmetric

Perianth

The perianth typically consists of two whorls of undifferentiated or weakly differentiated petaloid tepals with 3 distinct members in each whorl, or less frequently all of the segments are connate into a common perianth tube or perigynous or epigynous zone that sometimes has an adnate corona.

Androecium

The Androecium or male part of a lily flower is usually made up of 6 stamens.

Each stamen consists of a thin, stalklike filament with an enlarged end called an anther.

Pollen is produced within the anther. The pollen is released when a mature anther ruptures.

Gynoecium

The Gynoecium or female part of a lily flower is usually consists of single pistil which is made up of three fused carpels.

Syncarpous is the term applied to flowers with two or more fused carpels.

A carpel has three parts:

  • The stigma is the terminal portion that receives pollen. It is somewhat glutinous.
  • The style is the stalk connecting the stigma with the ovary below. It transmits the male gamete to the ovule.
  • The ovary which contains the female reproductive cell or ovule
Fertilization of the ovule results in the development of the carpel into a fruit.
