The technical term used for the androecium in a flower of China rose ($Hibiscus\ rosa$-$sinensis$) isWhen the filaments of the stamens are united into one bunch or bundle while the anthers remain free, the androecium is called monadelphous.
In china rose all the filaments are fused to form a single staminal tube around the style, so its androecium is monadelphous.
Diadelphous: stamens united in two bundles, as in pea (9 + 1).
Polyadelphous: stamens united in more than two bundles, as in citrus.
Polyandrous: stamens free from one another.
Hence the term for china rose is monadelphous.
