noun
centrifugal inflorescence
A botanical term for an inflorescence where the oldest flowers are at the center and younger ones develop outward.
遠心花序では、中心から外側に向かって花が咲いていく。
In a centrifugal inflorescence, flowers bloom from the center outward.
求心花序 is the opposite pattern, where the youngest flowers are at the center and older ones are on the outside.
Compound of 遠心 (centrifugal) and 花序 (inflorescence). The exact historical derivation is uncertain; the term is a modern botanical coinage.
