tubular flower; disk floret
Botanical term for the small, tube-shaped individual flowers that make up the central disk of a composite flower head (e.g., in sunflowers or daisies). Compare with 管状花 (かんじょうか), a synonym.
See also: 管状花 (かんじょうか)
Many tubular flowers are clustered in the center of a sunflower.
In Asteraceae plants, two types of florets can be seen: tubular flowers and ray flowers.
Refers to ray florets, the strap-shaped flowers often found around the edge of a composite flower head, contrasting with the central tubular flowers (筒状花).
Compound of 筒状 (tubular, cylindrical) + 花 (flower). The term is a modern botanical coinage based on the flower's shape.
