Mirbelia platylobioides starts to flower alongTourist Road

Mirbelia platylobioides is rampantly in flower along Tourist Road, Kangaloon, down on the flat dry sandstone edges, there, (not in the wet, swampy bits, nor in the tall, wet Eucalypt forest country).

Apart from some of the Hardenbergia plants in flower, this is one of the earliest of the local pea plants to come into flower.

 It is a prostrate plant (most of the time), with bright golden orange flowers.

 I like the heavily veined leaves of this plant.

 

 This is the flower as seen when one is walking along.

When the seeds are produced, the pods are hairy, 

and they have a flattened base, and are roughly flat in cross-section.

There is a depressed line down the centre of the pod.

Sunset serenade

As the sun set slowly in the west, 

I went out onto the back deck to listen.

If you have birds around your home, 

try to listen to their calls as the sun rises or sets.

Sunset from my back deck tonight

Blackbirds were whistling beautifully (listen towards the end of this sound file), with the occasional clattering cluk, cluk, cluk alarm noise (unfortunately, that call is at the start of the attached sound file - which gives totally the wrong impression of their beautiful whistling call).

Pied Currawongs were carolling in the distance.

Magpies joined in with some of their piping calls.

And then a pair of Kookaburras joined in, to bid the day farewell with their wonderful call.

Two new species of Orchids for me.

Technically, I have seen the first species before today, but only as dried (finished) flowers.
To say that the plant needs to be seen (when fresh) to be appreciated is an understatement.

These plants were found in the Budgong Fire Trail, in the Shoalhaven Vallly,,

It is called the Mayfly Orchid. Nemacianthus caudatus

What a weird and wonderful thing it is.

This is the first time I have seen this species.

I didn't know what it was at first.

Mount Rae Greys

My friend Mark Selmes, from Mt Rae forest, between Crookwell and Taralga, NSW often sends me images he has taken of the Grey Kangaroos and/or Wallaroos with whom he shares life in the Mt Rae forest. Tonight I am sharing some of his latest images.

His latest message was: "Pics - wild eastern grey with joey - spending a bit of time out of pouch,but sticking close to Mum."

"La Pieta" (Mt Rae style)

"Watching animals in the wild -especially at play- allows us to observe
qualities we all share

and helps us to realise that we have a common bond.
(even with the most maligned of species)."

Can I climb up, Mum?

"Without the world of nature in all its many forms 

we would all be poorer in spirit 

and eventually as natural ecosystems collapse so would our world."

"Hope you enjoy the pics, I know I enjoyed taking them."
Mark

Cute Joey - thinking up a prank to play on Mum.

My own comment is that Mark is (for his sins) now serving time on the Board of the Nature Conservation Council of NSW.

I have previously shared with you images of some of the lovely Orchids which Mark has found growing at the Mt Rae Forest, including the endangered Buttercup Doubletail Orchid, Diuris aequalis.

Having seen some of the wild creatures which live in the Mt Rae Forest, I am sure you will agree that their home ought be protected from native forest logging.

Better weather, better photos of Bird Orchids

Following on from yesterday's post on the Bird Orchids on the Budderoo Plateau, the weather was better today (at least not raining), and the flowers were one day more mature, and hence more open.

We found this particularly fine plant today,

just begging to be photographed.

Illawarra Bird Orchid - Simpliglottis chlorantha

While waiting to take these photos, I noticed that the labellum 

is very subject to movement on the wind.

These plants have a hinge in the labellum stalk.

The movement of the labellum was quite noticeable.

Here is a close-up shot of the osmophores (scent glands)

on the labellum of one of the flowers.

Compare the real thing 

with the botanical illustration below, (from PlantNET)

Labellum detail of the Illawarra Bird Orchid ("osmophores" or scent glands)

Unless you actually see these strange scent glands, 

it is hard to imagine that they are real. 

They look like green and red dobs of jelly, 

but are more solid than they look.

As a fringe benefit, I realised that there was tiny Flower Spider 

hiding up inside the column of one of these Bird Orchid flowers.

The yellow pollinia sacs are the point where

the Orchid needs a pollinator to come to. 

And that's where the Spider is waiting!

Cunning little things, aren't they?
It was tiny - not much bigger than a match-head.

Illawarra Bird Orchids start to flower on Budderoo Fire Trail

I have posted about the Bird Orchids of Budderoo Plateau in previous years.

I cannot help it.

They are so extraordinary, and so localised that I always feel a glow of satisfaction when I find them.

This year, they have started to flower today, 17 August. I have found them flowering as early as 19 July in 2008, and yet they have been known to flower as late as 23 September.

This plant is known also by the name Illawarra Bird Orchid -  a reference to the "open-mouthed" posture of a baby bird, begging for food.

I have been watching these plants for about 5 weeks, firstly as leaves, then as leaves with small buds, then leaves with large upright buds, and today flowers just opening, despite the light rain which was falling. Situation normal on the Budderoo Plateau. These plants grow in shallow soil over a sandstone rock shelf. They flower in late winter, and early spring, when the shallow soil is frequently wet. This heathland on shallow soil is a harsh environment, subject to extreme drying out over summer. These plants become totally dormant at that stage - they lose their leaves and hide under the soil. A good survival strategy.

I am referring to this plant by the name Simpliglottis chlorantha, but PlantNET obstinately refuses to recognise that name. So, when I refer to the illustration from their site, I use the name which they use, Chiloglottis chlorantha.

Note the extraordinary large calli 

or osmophores (scent-producing glands)

on the broad labellum (on left of image).

These plants grow in and under the low heath plants 

and "Eggs and Bacon" Pea flowers

which thrive on the shallow moist, peaty soil over the rock shelves of the area.

The genus name "Leucopogon" refers to "white bearded".
This plant is in the family Ericaceae, known as "heath plants"

 The flower here is seen from the side. 

The "lateral sepals" protrude out in front of the flower,

then curve downwards at their tips.

Illawarra Bird Orchid - Simpliglottis chlorantha - earns its green name (chlorantha)

This is a fresh flower, and so the labellum is held quite close 

to the column.

The large pollen grains (pollinia) are just visible

held above the labellum.

Note the green and red glands (calli) on the labellum

These Orchids have two fresh green leaves flat on the ground.

The leaves are often partially covered by leaf litter.

Illawarra Bird Orchid has a red throat under the labellum.

Daffodils "Tete-a-Tete" in flower (early) and Spring Wattles

Last year I published photos of these lovely little Miniature Daffodils "Tete-a-Tete" on 27 August. It coincided with Daffodil Day.

This year, these same plants are flowering two weeks earlier than last year.

Miniature Daffodils "tete-a-tete"

They are lovely little flowers, which I always find to be "cheerful" plants. Linguistically, I should say the make me feel cheerful.

The other thing which also makes me feel cheerful, at this time of year, are the Wattles. In fact I had some assistance today to clean up several trailer loads of branches of Wattles which were damaged several weeks ago, in the heavy winds which caused havoc around Robertson. So, this is a photo from two years ago. But the flowers were just as spectacular this year.

Acacia decurrens in my yard.

But this next one is a puzzle. The only truly natural wattles in Robertson are the Blackwood Wattles - Acacia melanoxylon. This other plant, however, is self-seeded in my front yard, but does not actually belong here.

It is now well over 2 metres tall, but I have been waiting for it to flower, so I could identify it, before deciding whether or not to let it grow. I wanted to know what it was, and where it might have come from, before making that decision. 

Acacia longifolia grows commonly at my friend Jim's place, at Carrington Falls, on the sandstone plateau there, in the heavy, black soil. It is rampantly in flower down there at present. My plant is just starting to flower.

Acacia longifolia - a native wattle which is not natural in Robertson

The leaves of this species are very variable, as demonstrated by these leaves taken from three separate plants, all growing along the same roadside edge, at Cloonty Road, Carrington Falls.

The top leaf is 230mm long.  The shortest leaf is approximately 130mm. These were all mature leaves - the longest ones on each branch I selected from. In other words, the shortest one was not just a small (undeveloped) leaf, on the end of a branch.

Acacia longifolia leaves - very variable in length.

Acacia longifolia - note "pulvinus" and gland at base of leaf.

"pulvinus: the swelling at the base of the petiole, often capable of changing form to bring about movement of leaf, sometimes glandular or responsive to touch. A similar swelling near the apex of a petiole is referred to as an upper pulvinus."

Flowers of this species of Wattle are in a "rod" formation.

Here is a better image of the flowers of another specimen of A. longifolia growing at Ulladulla - in flower last Saturday.

I have tagged this post as "Spring 2011", even though that is technically incorrect. It looks, smells and feels like Spring, so damn it, I am going to call it a Springtime post.
