We were quite amazed this, one and only flower we've ever had, lasted for over a month. So a number of shots shown here as it's ages.
On the 1st day it took quite a while to unravel, but by the 2nd day you can see the lower petals have crossed and the top petal hanging overhead in an arc; almost like a ballarina.
A large native orchid standing at about 300mm high, with the labelum being about 10mm wide and the petals approximately 40mm long.

Unfortunately we just missed out on seeing this one flower. They often don't flower at all, building up strength with just one leaf over the years until the time is right. This was the 1st we knew we even had this species at our home in the Adelaide Hills.
The largest leaf was ~40mm wide

Disa Bracteata

a
SynonymMonadenia Bracteata

A very invasive weed that's difficult to eradicate. Partly because they ALWAYS have two tubers. The first one comes up with the plant fairly easily, the second not so much. The second bulb will continue the plants life if not removed. Once the flower head has seeded it's very difficult to extract the plant without spreading seed further. The only way we know is to very genlty tilt the plant into a plastic bag (without any sudden movement) to catch anything that falls off and then dig it up. It's quite possible that cut & spray will work, but we haven't tried that.

Other Common NamesBlunt Greenhood or Midget Green-hood

The rosette is more typical of greenhoods, than the swan, being very flat and small.
The rear of the labellum (the appendage) is relatively flat.
Noting the rosette in early life (August) and marking the plants to monitor them, as we did, is the best way to identify them.
This year we found a large number of specimens whose rosettes varied dramatically. We thought we had several species, but all turned out to be just the one. Photo's are on their way.

Swan & Midget orchids look almost identical. The only differences are the rosettes in early life and the rear of the labellum when in flower. The rear of the labellum is not easy to see, so the flower head needs to be turned upside down to look inside, which then often triggers the tongue to close, hiding the rear of the labellum!
The rosette in early life is quite leafy. It shrivelled up when in flower.
The rear of the labellum has a forward pointing growth.
There was a question if this and P. mutica are synonyms. But they are listed as different species under the "Census of South Australian Plants", with no records of cross-breeding.
As we use Atlas (of Living Australia) as our name reference for ALL Australian species, as it's the only database we are able to download to check spelling; we will follow Atlas with this one.
