Flowers

Flower is that of the plant which is concerned in the sexual reproductive process of angiosperms. The formation of the flower is preliminary to the production of fruit’s seeds.

The flower consists of six parts. They are the calyx the corolla, the stamens or stamina, the pistil or pointal, the pericarp and the receptacle.

The outer-most circle of the flower is called the calyx from the Latin word meaning cup. Its duty is to protect the more delicate parts and organs within. Within the calyx is the corolla, which has a Latin name meaning little crown. The corolla is that beautiful part of a flower which attracts our attention from the variety of its tints. Its duty is to protect still more the seed-producing organs in the centre.

Within the corolla there is a circle of slender stalks. Each of these has a small knob or long, tube-shaped structure and its tip. These stalks are called stamens from the Latin word meaning thread. They have two parts – the filament and anther.

The filament is the stem of the stamen. Its only duty is to hold up the knob at its top. The anther is a knob at the top of the filament.

The innermost organ of the flower is the pistil. It is the seed-producing part of the flower. The pistil consists of three parts: the germen or future seed-vessel; the style and the summit or stigma. The stamens and pistil form the most essential parts of a flower.

Neither sepals nor petals are directly involved in seed production.

The pericarp is in fact the germen grown to perfection. It varies considerably in form, size and substance.

The receptacle is the base or bottom part of the blossom. It generally stands between the calyx and corolla, and supports or connects all the remaining parts of a flower.

Flowers should be collected prior to or just about the time of pollination.
