Morphology

calyx + tube

The meaning is directly compositional: 'calyx' (the outer sepals) combined with 'tube' (a cylindrical or cup-like structure) yields a tubular structure formed by the calyx, so a learner who knows both constituents can infer it denotes the tube-like part of the flower. Although botanical and domain-specific, the sense follows ordinary noun + noun composition and is predictable across languages and contexts.

Etymology

The noun calyx tube comes from a simple shape idea: calyx is the cup-like part under a flower and tube shows its long, narrow form. So the name describes the part that holds and 'protects' the flower's inner parts like sepals and stamens.
