Datura flower is a funnel-shaped flower and can be seen in creamish white, pink or light violet colours.
The following parts of Datura flower are given below Floral Parts:
(a) Pedical: Small green stick-like structure, which holds the flower on the stem.
(b) Thalamus: The top of the pedical forms a flat disc-like structure. The thalamus holds all other parts of the flower on it.
(c) Calyx: The outermost cup-shaped green structure is the calyx. In this flower five green leafy sructures unite to form the cup-shaped calyx. These five leafy structures are called sepals.
(d) Corolla: The whorl of petals next to calyx is known as corolla. In Datura flower corolla may be creamish white pink or violet in colour.
Sexual Parts:
(a) Androecium or Stamen: It is the third inner whorl of a complete flower. It is composed of five stamens. Each stamens has two parts, the lower position of it is a five thread like filament and the upper position is an elongated swollen anther. In Dhatura flower the filaments remain attached to the petals but the anther remain free. Each anther has two lateral lobes joined side by side. Within anthers numerous pollen grains are stored.
(b) Gynoecium or Pistil: The innermost whorl of a complete flower is the gynoecium or pistil. The unit of gynoecium is called carpel. Datura flower has two carpels in its gynoecium. The two carpels join together to form a long-necked pitcher-shaped structure. The swollen base of it is the ovary which holds ovules in it. The long tube-like part emerging from the ovary is called style. The apex of the style is slightly swollen and sticky, it is called stigma. Stigma catches the pollen grains during pollination.
