I had hoped to find masses of Sun Orchids at Penrose, but the weather was not in my favour. But there were many Beard Orchids out (Calochilus platychilus). The Purplish Beard Orchid (formerly known as Calochilus robertsonii)
|Lilac coloured Diuris punctata and Podolepsis daisies.|
In a closer shot you can see the masses of Diuris.
|Diuris punctata amongst the Podolepsis daisies.|
Here is one of the large-flowered Diuris punctata
|Diuris punctata - lilac form.|
Here you can see a Beetle which is busy eating the Diuris flower.

|Oligochaetochilus calceolus - labellum has been triggered closed|
The Labellum of this plant has long fine "spikes" (trichomes).
The Labellum is movement sensitive, as part of its reproductive function
for the labellum senses if an insect comes to the flower, and
the labellum snaps shut (as in the previous image).
On the way back to Marulan, I found where there is another species of the "rufa" group, Oligochaetochilus aciculiformis. These plants were quite small, and very hard to find.
This flower has a different pattern of hairs on the labellum
to the previous species.
Tiny short hairs at the top and bottom of the labellum
and long hairs on the sides.
|Oligochaetochilus aciculiformis. Note the short hairs as well as the long ones on the side.|
