More than orchids

Orchid hunting is not all about finding the most interesting, rarest and amazing orchids.  It’s an opportunity to immerse myself in the bush, and relax.  There are many beautiful things to see and enjoy.  Recently I saw this Egret with its mating plumage.

Egret

The bush has many beautiful and amazing areas that are such a pleasure to see.  Below are a few pictures of the patterns created by the trees.

DSC02953Sometimes I am fast enough to capture birds, but since most of the time I have the macro lens on, that is not very possible.

Misitlo birdThere are some days when I return home to look through my pictures and find something unexpected such as a mosquito captured in frame!

Orchids are beautiful but there are so many other surprises in the bush that are waiting to be found.

Ducks

Currently there is not a lot happening in the orchid world.  So today’s post is all about duck orchids.

As I had a bit more spare time over the last couple of months, I decided to try and capture the beauty of the Small Duck orchid in a pencil drawing.  The flower would easily fit inside a thumb, so my drawing is substantially larger than the actual orchid.   I did draw from a photograph that I had taken.

There is somethings so beautiful when you meet someone who is truly excited about learning.  And what’s more a teacher learns from their students.  Recently at an orchid society meeting, one of the members was very excitedly telling me about recently seeing the duck orchids and discovering how the flowers behaved and were pollinated.

I was able to point out that the duck orchid actually has a sensitive labellum, a feature that is common is several species of Pterostylis and in Bunochilus, Urochilus and OligochaetochilusThe ‘head’ of the duck orchid flips down into the ‘body’ of the flower trapping any pollinator.  This can be seen in the centre right picture.  However I had never really thought about where the pollen of the flower is, until the member asked me about a yellow spot on all his photographs!  The pollen sits at the base of the body which means the pollinator has to pass over it to escape out of the orchid and thus pollinates the orchids.  It can be seen on the duck on the far left.

100th post: Questions and Answers

Wow, 100 posts, and I was never keen on writing those English essays!  So as promised this post will be a Questions and Answer post, and thank you to everyone who submitted a questions.  They are good questions and I will try my best to answer them.

Do Australian Orchids have one season?

In Australia one or more orchid species will be flowering at any given time of the year.  Currently our summer orchids are in flower, although many of the summer orchids actually grow in swamps and thus are rare.

As I was curious as to the number of species flower per month, I took all the species that grow in South Australia and plotted them for each region.  In the northern parts of South Australia due to desert there are only one or two species present, which tend to flower in spring.  However in the southern, wetter regions, there is more likelihood of finding an orchid in flower any time of the year.  From the averages of all the regions it can be seen that the peak in the orchid season is at September to October (the beginning of Spring).

As a keen photographer, I would love to know – in a general sense – where you find a lot of your orchids?

Generally I don’t say where I find orchids partly because some of the sites that I visit are sensitive and it is not wise to have a large number of people visiting the locations.  Also with some of the rarer species, in particular the Duck Orchid, are prone to digging because people do not realize how difficult they are to grow.  No one, not even the experts have been able to grow it.  It is also illegal to take any plant (even picked flowers or capsules) from the wild without a licence.

However there are a lot of locations were you can find orchids.  Where there is native habitat in good condition, there should be orchids.  These include the Mt. Lofty Botanic Gardens (I was up there last Saturday and Dipodium are still flower – even some in bud!), Morialta Conservation Park (take the track on the left to the second falls as it has numerous winter/spring orchids growing along the edge), anywhere in Belair National Park which is a hive for orchids and actually has a few rarer species growing there.  There are many other locations in the Adelaide Hills where they can be found.  Pretty much it comes down to having quick eyes and knowing what habitat the different orchids like.  Anywhere where there are few weeds, there will generally be orchids growing.

A really good way to discover more locations and orchid species is to join an orchid club and go on an excursion with others.  I personally would recommend the Native Orchid Society of South Australia, but have I mentioned that I am their Assistant Editor?!

Arachnorchis tentaculata

The King Spider orchid – Arachnorchis tentaculata – found at Scott Creek Conservation Park

There has been a fire in the Belair National Park, is it likely that there will be a flush of orchids in the fire location come Winter/Spring?

Fire and orchids is such a complex topic.  For those who aren’t local there was a bush fire which occurred a couple of weeks ago in a national park pretty close to the city of Adelaide.  This coming season I would expect to see more orchids flower in that area, in particular the fire orchid.  I will be checking it out later this year to see what happens.  I’ve written about orchids and fire previously.

However there are long term effects of fire that are still being researched.  The following article is highly recommended reading:

Why some orchids have the trigger mechanism and some don’t?

What a lovely questions – I wish I knew the answer!  There are a number of species that have labellums that can move, from Pterostylis which flowers in the winter to the Duck Orchids which flower in late spring.  They all have different pollinators and the flowers look different.  The trigger mechanism is just one method for being pollinated.  Other orchids use different methods such as imitating a female insect or imitating another flower.  This article could be of interest:

Thank you everyone for your questions.  I learnt a few things from writing this post and I hope you did to.  Orchids are so complex and amazing!

Victorian Orchids

South Australia is the only state in Australia that does not have any epiphytic orchids.  Our state is the driest state in Australia and does not have any rainforests that could offer a suitable condition for them.  So here is a video about some orchids that grow across the border in Victoria.

In Summer…

After having four consecutive days of over 40C (104F) heat, I’m pretty sure that there are not many orchids left in flower now.  However a weeks ago, the hyacinth orchids were in full glory.  Dipodium roseum is one of the most photographed orchids in Australia.  It is often found on road side edges which makes it easy to spot.

Dipodium

It is one of the largest terrestrial orchids and can grow a few feet high.  It grows around Stringy Bark trees as it needs a special fungi to survive as it has no leaves.  Can you spot it/them in the picture below?

DSC02938

This particular species is distinguished by having stripes (rather than spots) on the labellum.  The flowers vary from pink to a soft white, and can be growing on either a dark stem on green stem.  Personally I prefer the pink flowers on the dark stems and sometimes seem to forget the other variety.  Here are two variations growing together.

Looking towards 2014

DSC029042013 was quite a fun year, and saw OrchidNotes first year anniversary in April at about 100 subscribers and in June we hit 10,000 views.  By the end of the year, both those figures had more than doubled.

WordPress has put together a summary of the statistics for OrchidNotes.

The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 16,000 times in 2013. If it were a concert at Sydney Opera House, it would take about 6 sold-out performances for that many people to see it.

Click here to see the complete 2013 report.  If you like, you can compare it with the 2012 report.  It’s so exciting to see this website growing.

And as a teaser, my next post will be about Dipodiums.  I’ll hear from you then.

Some of my favourites

So I’m back!  I’ve enjoyed having a break from blogging while my non-orchid life has been busy and full of pleasant surprises.  Anyway it has been lovely to see that people are still looking at this blog, but I do feel a bit guilty for having not posted recently.  I’ve heard from others that they know someone who reads this, and I find that really nice to know that I make others happy by sharing orchids.  Please say “hi” and let me know where you are.  I would love to hear from you all.

So for today’s post, I’m just going to re-share a few of my favourite pictures from this year.  I did not get out as often as I would have liked, but I always looked forward to hunting for orchids.

Eriochilus cuculata (1)

First off we have Eriochilus cucullatus.  A friend told me about a lovely patch of Eriochilus cucullatus and gave me the coordinates to find the colony.  There were well over a hundred plants scattered across quite a distance.  I really like this pictures with the pollen sitting on the labellum.  I still don’t know how the pollen arrived there.

Fungi

In June, my digital camera tricked me into believing that it had stopped working which worked out very conveniently because I was able to upgrade to a digital SLR camera with multiple lenses.  It’s been great fun to learn to use it properly.

Pterostylis curta

The picture above was lots of fun to take.  The orchids are in a pot, and I set up the camera on the tripod, and zoomed in from a long way away.  The picture was actually taken indoors with the window to the front garden as the backdrop.  There was just enough afternoon sun to capture the golden colours.  This image has not been edited.

Arachnorchis rigida

I was really excited to see the Arachnorchis rigida this year, after not having seen it for awhile.  I love the crispness of the flowers.  At this point I had not learnt how to colour correct the camera so there is too much blue, but I think it kind of worked for this picture.

Arachnorchis tentaculata

Eventually I learnt how to colour correct.  The bush does have a beautiful golden colour which I feel has been captured in the above picture.  I did not realized that these two spider orchids had different coloured stems until I was looking through my pictures later.  I took this picture when I was planning to photograph a field of cockatoo orchids.  That day we were expecting a storm, and thankfully I was able to take my pictures before the wind had picked up and while the sun was still out!  Below are the cockatoo orchids.

Glossodia major

While the field was still spectacular, many of the flowers had already finished.  Maybe next year, I can catch them earlier.

Caleana major

Everyone’s favourite, the large duck orchid.

duck orchidThis year finished by seeing both the duck orchids.  These are always a favourite and every year I seem to forget that they are smaller than I think!  The whole flower of the small duck orchid would be less than 1.5cm high.  I particularly like how these two small duck orchids turned out.

Below is a gallery of other pictures that I enjoyed taking.
