Small colony. Only two in flower and they looked like they were finishing. The petals were small, but I could not check the calli as the flowers were closing, but feel confident they were not C. valida, which I have seen many times before.
Hi Peter, I think on current knowledge there is only C valida locally. (There is a C aff valida which is chemically different but it is visually identical). I'm not sure that the C aff valida in the ACT orchid book is still present or still recognised.
