Arnold, I run into the same reference in marine biology books. For botany, lithophyte is the general expression for rock growing. I find some of the terms a bit wanting in that they are inconsistent, but, so is it... we must adapt ourselves! So we have, epiphyte, lithophyte, geophyte, saprophyte, hmmm, dendrophyte, what else?
