Thank you Reiner Richter & Geoffrey Cox for confirming the id of this species for us

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 ~300mm high, with the labelum being ~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.
Woo Hoo, we got the flower this year (2018) images coming soon!

African Orchid
Disa bracteata
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.

Thank you Tony and Jenny Dominelli for confirming the id of this species for us

We were very excited to find this little single stemmed plant under mallee trees, amounst the leaf/bark litter.
The whole plant is only 160mm tall, with the fruit cluster only 15mm high.
We missed this flowering last year, but now we just caught it in April ... last flower remaining.
In our area the only other midge orchid it could be is Red Midge-orchid (Genoplesium rufum).
In relation to the "sheath" photo, Robert Lawrence said "This genus only has one leaf and that is tightly wrapped around the scape. What you have in this picture is the sheath that protects the new shoot until it emerges from the ground."

Two-bristle Greenhood Orchid
Pterostylis biseta
Other Common NamesRustyhood or Veined Greenhood

These are fascinating flowers. The two bristles are sensitive to motion. John Smyth tells us this is called an "irritable labellum". An insect will land on the labelum, attracted to the flower by scent. This will trigger the bristles to close the labellum, trapping the insect inside the flower tube. It's only way out is to follow the tube and escape. In the process is brushed against the pollen, thereby fertilising this flower, or taking it's pollen to another

Midget Greenhood Orchid
Pterostylis mutica
e m
SynonymsHymenochilus muticus or Oligochaetochilus muticus

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.

Thank you Adam Dutkiewicz & Robert Mitchell for identifying and Robert Lawrence & Rusty Ryder for confirming the id of this species for us

The first flower was originally id'ed as T. nuda.
When this happened we questioned Robert Lawrence about the 2nd flower, being a different coloured hood, and he said "It is certainly not typical. It could be leucistic."
