Morphology
A learner who knows 'semaphore' (a visual signaling device) and 'plant' can compositionally infer this refers to a plant that signals or displays movement, so the general sense is accessible from the parts. However, the precise biological detail—that small lateral leaflets rotate in response to sunshine—is specialized and not fully predictable from the constituents alone, so the expression is only partially transparent.
Etymology
Semaphore plant may come from the way its small leaflets move like flags or arms people use to 'send signals'. That's why the name refers to a plant that seems to 'signal' by moving its leaves.
