AusBonsai

Can anyone help with the I.D. on this one please. They are a bush/small bushy tree that grows prolifically along the creeks in the Gold Coast hinterland. the new foliage is this red colour but mature leaves are a mid green. They have yellow flowers about the size of a 10 c piece.
I have tried a couple of plant ID apps on my android phone, but they all come up with North American plants. Can anyone recommend a good plant ID app. for Aussie plants that I can download to my android phone?

Looks like Ochna serrulata

Pretty bad environmental weed in SEQ

Pretty bad environmental weed in my front garden too ... they pop up everywhere!

Yes, definitely ochna serrulata. Thank you. Yamadori dig coming up.

Yep it is. And is great rootstock for grafting Vietnamese ochna integerrima. Here were what I tried last year.
Cheers
