What is Dithecous Anther?
The name “dithecous” is derived from the Greek words “di” (two) and “theca” (pollen sac). Each theca contains microscopic structures known as pollen sacs or microsporangia. Theca formation in a dithecous anther occurs when the flower’s reproductive components grow. The anther starts to form when specific cells emerge in the early stages of flower development.
In a flowering plant, the anther is commonly divided into two sections, which are known as lobes. These lobes are commonly referred to as bilobed anthers. Each lobe of the anther comprises two chambers known as thecae. These compartments are where pollen grains are formed. Dithecous anther lobes are those that have two compartments each. Examples are angiosperms and crotalaria, solanum, and mustard.

Dithecous Anther – Structure, Formation, and Theca
The dithecous anther is a bilobed structure found in flowering plants’ stamens. The dithecous anther consists of four microsporangia, two in each lobe. Upon maturation, the anther undergoes dehiscence, releasing pollen for pollination and fertilization. Dithecous anthers examples include solanum and mustard.
The dithecous anther plays a crucial role in the sexual reproduction and genetic diversity of angiosperms. In this article, we will learn about the structure, function, and formation of the dithecous anther in detail.
