help with diuris ID
I wish I could help with this one audz. I love all the fantastic terrestrial species but am really not that experienced with the southern types. I know a bit about the tropical ones but that won't help us with this one.
Others here may be able to help with ID confirmation I think.
Tops photo and the info you added is great!
Regards wellsy
Thanx wellsy
Hopefully some knowlegeable& helpful soul will inform ;) Will add more pics in the hopes of identification....Native Aussie Terrestrials are Intriguing to me.
Diuris sulphurea
Info from an old book of mine on 'Native Orchis of Australia' authors Leo Cady and E.R.Rotherham
This coud be Diuris aurea. Spring flowering terrestrial from NSW and Queensland.
Bernard
Diuris sulphurea or aurea
Hi Bernard, nothing wrong with old books, there is some great info in them.
Has your book got a photo of aurea and if so, is it pure yellow and how many ridges can you see on the labellum????
Bill
Diuris sulphurea or aurea
Bill- The picture of aurea in this book (as in most old books with colour images) is not very clear and not sharp enough to determine the number of ridges on the labellum. The so-called ears are a clear golden yellow, the dorsal and labellum same colour with a few brown spots. The tails are mostly green with some yellow inside.
According to the authers D.aurea is similar to D.sulpherea differing in the colour of the flower and the shape of the labellam and by having two raised callus plates at the base of the labellum. It is very variable in colour and in the shape of the labellum mid-lobe, which varies from almost orbicular to ovate, the flower colour varies from golden-yellow to orange-yellow with brownish marks.
To further complicate matters, the authers are of the opinion that in the western plains area of NSW a large number of species have been described which have origintd from cross-fertilisation.
hope this helps
Bernard
Diuris sulphurea
That is great info Bernard, clearly tells us that aurea has two raised callus plates on the labellum.
A.N.O.S.-Qld. Kabi Group use sulphurea as their floral logo and the description is one single ridge on the labellum as the photo above shows.
I think we can put this to bed now as Diuris sulphurea.
Bill
Diuris aurea or sulphurea ?
I just checked my "Field Guide To The Native Orchids of Southern Australia" and I am afraid to say it doesn't resemble either the Diuris aurea OR sulphurea.
The lip on both these plants is far bigger than this image you have posted.
The aurea doesn't have the two round shaped petals above the flower as this image does, and the sulphurea has large elongated paddle shaped petals above the main flower. I can scan them and post them if required.
It most closely resembles the D.laxiflora if anything.
Interesting, I think I know just the person to help out.
On the box it said Windows XP or better, so I bought a Mac !
Diuris continues!!!!!
Thanks Anton, I was hoping this Diuris was asleep!!!! lol
The most important thing is that we get the correct info on the Website. Trying to identify species orchids like this one is very hard considering the angle of the photo that we have to work with.
Anton and anyone else that is interested, please take a look at this link, www.ourshopfront.com/kabi/ Go to orchids of Brisbane for photo of Diuris sulphuria.
Let us know what you think Anton, it might save you scanning and posting from the Field Guide.
Bill
It Sure Does Continue !!!!
This site shows the Diuris sulphurea very well, and I STILL think it looks different to the image here. ;o))
http://orchids.rnr.id.au/Diuris1/index.html
But, I have been know to be wrong once....or twice. :oD
Interested in your thoughts on these images. As a photographer I just wish people would take a little more time to
capture images of plants a bit better to show detail.
I have a few terrestrials on my web site in the ORCHID SECTION, SUBSECTION AUSTRALIAN NATIVES.
www.antondrew.com Interested in what you think.
Bill, I have sent your image to Kevin Western, one of Australia's top native cultivators for ID as well. He is a personal friend
of over 30 years, we'll see what he comes up with.
Anton
I'm not responsible!!!lol
I'm not responsible!!!lol
Thanks for the credit Anton but it's Audz's photo not mine.
Hopefully Kevin can identify it for us but I think he might be out of town at the moment.
Diuris??????
Hey debatees! I have more pics!!! Want me to add them??? Confuse you all more...spark more debate??? <3<3<3 I LOVE THIS <3<3<3 Audz....
absolutely...
absolutely...we love a good friendly debate here.
We love it even more when we get a good outcome and settle the original reason for the debate.
Regards wellsy
Should you let sleeping dogs lie ? ;o))
Kev Western has taken a peek last week, and said there are too many variables to put an exact name to this flower.
It may be a loner, or part of a group. He came up with a list of questions to ascertain how you would decide
if it is the D. sulphurea, so, we decided to put it in the too hard basket.
So, if someone wants to get to the bottom of this and has the answers he requires, give Kev a buzz.
Anton
Diuris sp. is the best name?
so Diuris sp. is the best name for this one at the present time I guess?
Do we all agree?
Regards wellsy
Agreed
All in favour say AYE !
Aye ! :o))
Anton
Diuris.....
Can I get in touch with Kev Western??I may be able to answer all on the long list....Audz
