Study Notes
- A stamen consists of a filament and an anther, with the filament attached to the thalamus or petal of the flower.
- The number and length of stamens vary among different flower species, leading to a wide range of sizes in nature.
- An anther in angiosperms is typically bilobed with two theca in each lobe, making them dithecous.
- There is often a longitudinal groove that separates the theca within each lobe of the anther.
- Detailed observation and diagramming of stamens from different species can reveal the diversity in size, shape, and attachment of anthers in flowers.
