What are monadelphous stamens?

Monadelphous stamens are stamens in which the filaments are fused together into a single bundle, while the anthers remain free.

This condition is commonly found in plants of the Malvaceae family, such as hibiscus (China rose). The fused filaments form a tube-like structure around the pistil.

Example: Hibiscus (China rose)

Important Exam Point: In monadelphous stamens, only the filaments are united; the anthers remain separate.

Quick Fact: "Mono" means one and "adelphous" means brotherhood, indicating that the stamens are joined into one group.
