O is for orogeny

OMG. It's an orchid [R possibly Dactylorhiza incarnata] a group of plants so called because their roots look like testicles = όρχεις in Greek. In Irish it's the same lus na magairli = herb of the stones/testicles. There are 56 native species [illustrated PDF guide BMNH] on These Islands. Heaven forfend that anyone should suffer an orchidectomy because of testicular cancer.
