Diuris are commonly called Donkey orchids because of the prominent top petals.
Diuris orientis was formerly known as Diuris corymbosa.
This species has quite some variation on the coloration, as seen by the almost yellow flower below.
I have found them quite abundant in
Flora & Fauna Reserve as well as
Baluk Willam Flora Reserve
They never seem to be by themselves, I have always found several within metres of each other.
At first glance the
Diuris sulphurea (Tiger Orchid) and
Diuris maculata (Leopard Orchid) seem similar but
the Wallflower Orchid has larger flowers and a soft edge between any dark colors and the yellow.
