If you can get a photo of the underside of the leaves Hirere. If you look closely you should be able to see a few c. 2mm long whiteish hairs if it has hybridised with P. tomentosa
Hi Mike, apologies for late reply. I'm not too sure if this photo is any better than the last, but here is a photo of the underside of the leaf.
Another underside shot
And the top side
Thanks Hirere, I can't see any hairs on the leaves so think this is Pimelea orthia which is a nice discovery to make. Well done
