Waterfall Orchids in full flower now.

This late summer season (if that's what it can be called) is looking like a good season, (if somewhat compressed in flowering time).  Other local Orchid enthusiasts confirm this impression. Nothing happening two weeks ago, and suddenly there is a "rush" of flowering.

After a very dry season through until the end of January, followed by torrential rain, then another dry spell, followed by yet another torrential dump of rain, the summer Orchids now have to rush to get their flowers opened, pollinated, and their seed capsules ripened, while the warm weather lasts.

Today, my friend Kirsten and I inspected the "Waterfall Greenhoods" (Diplodium pulchellum) at one of the local Waterfalls. There is one in particular plant which has a terrific flower, and easy to access.

The others closer to the river are also going off.

And lots of non-flowering rosettes are evident, which bodes well for this colony for next year too.

First of the new season Orchids

With Orchids, one cannot easily classify them into seasons - Winter/Spring/Summer and Autumn flowerers. Well, I use such a grouping for filing my photos, but it really does not "fit" with the reality of our seasons.

Tonight's plant is a good example of just such a problem. I think of this group of flowers, Corunastylis, as "autumn flowerers". They will be around until April, though mostly they are found in March. So I tend to file them as "autumn flowerers".

This year, we have had a burst of very heavy "late summer" rain - post cyclonic rain, in fact.

But with that rain has come a drop in temperature, the birds are behaving as if they are preparing to migrate north (those which move, anyway). And with this change in weather, up pop the first of the Corunastylis.

So, the real answer is that our Euro-centric phrases for our Australian Seasons simply do not match the reality of our seasons.

There is a similar "mis-match" towards the end of our winter. I have dubbed that time the "Season of Anticipation" when Wattles and Jonquils are in flower, and Peony buds burst through the soil. I have written about that problem before, but I have not noted the end of Summer - early Autumn seasonal mis-alignment previously. To be fairly clinical, I could simply call this season the "End of summer rainy period". It is not a romantic term, but it definitely fits Robertson, anyway. It would not fit Canberra, I know, and not Melbourne either.

However, to the point, here is the first of the new season Orchids - Corunastylis fimbriata. The "Fringed Midge Orchid". The PlantNET people still use the old name of Genoplesium fimbriatum. Have a look at Colin and Mischa's images of this species from NSW.
Note the very long "cilia" (hairs) on the tip of the Labellum
(botttom right of the image)
This "find" was a bit of a thrill for me, for while I have seen this plant once before, at Tallong, when looking for another rare species there, I had not managed any decent images of that plant.
This next image shows the other main diagnostic feature of this plant
which is the hairs lining the edge of the dorsal sepal.
You need to remember that these Orchids are "upside down"
to most Orchids, and the dorsal sepal is underneath the flower.
It is the pale green "boat-shaped" structure, with a few red lines on it.
The Dorsal Sepal is pointing downwards and backwards, at a sharp angle.
Compare this flower with the bare edges of the dorsal sepals of
Corunastylis sagittifera, which is otherwise very similar.

These tiny Orchids are very hard to photograph successfully and I will try again, even on this one specimen. But the thing I did like to see (and one cannot capture it without close-up Video footage), is that when I found this plant the little hairy labellums (labella?) were flapping in the warm, gentle breeze. David Jones in his main text, is at pains to point out the flexible nature of the hinge of the labellum. And here they were flapping in the gentle breeze. I have seen many other Corunastylis species, but I have never seen the labellum move so easily.

Here is a shot of the top of the flower stem of this particular plant. There are several others nearby, but this was the first to open.

These plants were growing in very poor sandy soil. This was close to, but definitely not in, Butler's Swamp - where the soil is peaty. Not so, for these Corunastylis - they were in pure sandy soil. I even found several plants budding up in a shallow depression in a large rock, where there appeared to be less than 2 cm of sand in the depression. The surrounding habitat was classic Southern Highlands "Sydney Sandstone" scrub, with Scribbly Gums, Stringybarks and Proteaceous shrubbery.

Another Moth - Proteuxoa sanguinipuncta

This charming Moth was hanging around my front porch two nights ago. I had not seen it before.

It looked a little like the Hunchback of Notre Dame, I thought, or else a very overweight Rugby Prop Forward (scaled down, and then dressed in a winter overcoat). It might even be thought to resemble a member of the Russian Mafia, with that rich fur stole around its shoulders.
According to Donald Hobern's very useful FlickR Gallery of Australian Moths, it is Proteuxoa sanguinipuncta. It certainly has blood red spots (as per the second name).

According to Don Herbison-Evan's site, its caterpillars feed primarily on grass.
The lower sections of the fore-wings (the only ones visible, when it is at rest, like this) are richly spotted with red, and dusted with gold and brass-coloured flecks.

It is not a showy moth, but by far one of the prettiest I have seen in a while - and it appears to be a native.
The Ermine Moth is prettier (but it is introduced). So tonight's Moth is OK, by me.
