Which term describes stamens united into two or more bundles, as in citrus?

Explanation:
Stamens arranged into bundles is the key idea here. In citrus, the filaments don’t all fuse into one single stalk (monadelphous) and they don’t split into just two bundles (diadelphous). Instead, the filaments form several distinct bundles, more than two, around the flower. That pattern is described by the term polyadelphous. The other option, polyandrous, would point to having many stamens, but not specifically to how the stamens are grouped or fused, so it doesn’t capture the bundle arrangement the way polyadelphous does.
