Orchid taxonomy is ever-changing and many of the orchids in Our Patch (my copy is dated 2007) have been split into several other species or renamed. Thelymitra pauciflora has since been split into T peniculata, T brevifolia, and I suspect a few other things we don't have in our area. I believe T nuda has been split into T alpina, T megcalyptra and probably more. I guess in that regard Our Patch is still pretty accurate, it just hasn't kept up with orchid taxonomy...
