Identifying Australian Native pea flowers is very difficult. I have many photographs of flowers that look slightly different, and I have spent days trying to work out whether they are the same species or different species. In my search I have discovered that there are many different species of Bush-pea, Bitter-pea, Parrot-pea, Wedge-pea, Flat-pea and Eutaxia, all of which look like variations of the same flower. This means the shape of the leaves, whether the flowers cluster or grow along the stem, whether the large back petal is standing up or laying flat, whether it is divided by a line or is smooth all the way around, how much red and yellow there is, and where these colours are distributed are all meaningful identifiers.
Using all of these identifying features, I am pretty sure, but not 100% sure, that this flower is a Bushy Parrot-Pea. The reason I chose this over similar looking flowers is due to the shape of the leaves, and the way the red on the large petal seems to follow the separating line right to the top of the petal. Other similar flowers just have yellow on the separation line. (Sorry, I don’t have a lot of botanical language, so feel free to provide me with the correct technical terms if you know them).
Our property was alive with pea-flowers in Spring. This photograph was taken in October. I will continue to try to identify the various species as time permits. Some of the most beautiful flowers are proving to be the most difficult to identify.

Maybe you’ll find a new species or sub-species!
Yes, I think I have a secret dream of doing that! Possibly won’t happen, but nice to contemplate! Lisa
Check Dillwynia glaberrima, Smooth Parrot-pea which has long leaves and fowes in clusters. Compare it with D ramossima which has shorter leaves, stems often ending in spines and solitary flowers. Let me know what you think.
Hi John, I see what you are saying. This is the photo I looked at when making my initial assessment http://www.cpbr.gov.au/cgi-bin/phtml?pc=dig&pn=4919&size=3. It seems to have long leaves and the flowers seem to be a closer colour match than the photo I was looking at for Dillwynia glaberima, which I also considered… here which seems to have some white showing between the red and the yellow on the flower.
However, I opened up a few more images for both of these and on most of the other images for Dillwynia ramosissima show much more rough-edged long leaves, so maybe the image I was looking at was mis-labelled?
I agree that the leaves on the D glaberima look to be a closer match, but the flowers on this species don’t quite look the same. I’m interested to know if you think the images I’ve linked to are representative of the plants as you know them? There are so many different flowers, all looking vaguely the same I find it really confusing. I’ll contemplate more on this and try to identify a second pea flower tonight. I have a favourite image which I am closing in on and would appreciate your opinion on that one too. Thanks, Lisa
Photos are often not very help for identification. Colour of flowers varies and size is difficlut to determine. I prefer to use PlantNET which often comes up when a scientific name is googled. The clear diagrams of useful. Try this link: http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Dillwynia~glaberrima
The flowers are in a terminal cluster rather than spread singly along the stem.
Thanks for the link John. I’ll have a look at this tomorrow. Lisa
