Morphology
rein + Orchis
The first element 'rein' is not a transparent English lexical item here (and would more likely be read as the strap 'rein'), while 'Orchis' only signals an orchid genus and does not convey the specific ‘kidney-shaped lip’ feature. The botanical/Latin origin and the specialized morphological meaning are not inferable by a B1 learner who knows the constituent words, so the expression is not compositionally predictable.
Etymology
Rein orchis may come from an old word for 'kidney' because the orchid's lower petal looks like a small 'kidney'; the part rein points to that shape and orchis is the name for the orchid plant, so the name simply describes the plant's kidney-shaped part.
