Parts of a Hibiscus Flower

The Hibiscus (commonly known as China Rose) is widely used in biology labs to study flower anatomy because it is a perfect, complete flower. It contains both male and female reproductive parts clearly visible to the naked eye.

Key Facts

Male Part: Stamen (Filament + Anther).

Female Part: Carpel/Pistil (Stigma + Style + Ovary).

Hibiscus is a Bisexual flower (contains both male and female parts).

1. Non-Reproductive Parts

  • Pedicel: The stalk that supports the flower.
  • Receptacle: The swollen base of the flower where all parts are attached.
  • Sepals (Calyx): The green, leaf-like structures at the base that protect the flower when it is a bud.
  • Petals (Corolla): The large, bright red/pink structures that attract insects for pollination.

2. Male Reproductive Parts (Stamen)

The male part is collectively called the Stamen. In a hibiscus, many stamens are fused together to form a central tube.

  • Filament: The thin yellow/white stalk.
  • Anther: The tiny yellow, swollen tips on the filament that produce and hold the pollen grains (male gametes).

3. Female Reproductive Parts (Carpel/Pistil)

The female part is collectively called the Carpel or Pistil. It runs right through the center of the stamen tube.

  • Stigma: The sticky, dark red, 5-lobed structure at the very top of the flower. It catches pollen.
  • Style: The long tube connecting the stigma to the ovary.
  • Ovary: The swollen base hidden inside the receptacle containing ovules (eggs).
