I planted some seeds from my Australian Round Lime tree's fruit a couple of years ago.  The seedlings look very unusual, the leaves don't look like the parent and they resemble conifer needles.  Wondering if it's a hybrid with one of my 25-30 other citrus trees. Anyone seen anything like these before?

Probably not a hybrid. Citrus australis has a juvenile leaf stage and a mature leaf stage. Over time the leaves will go from conifer shaped to diamond shaped leaves.

Looks like a thorny rosemary.

They do look a little unusual. Are they under strong grow lights that could compact growth/ short nodes ?
Each individual leaf looks a little different to the australis seedlings I have grown before.
I will double check some of my seedlings for leaf shape.
You could try tasting a leaf from the seedling and the seed tree to see if there is any strong difference indicating a hybrid.

I think those are juvenile leaves.

Yes definitely Juvenile leaves, and long and strap like, as usual for C. australis.
Being in Australia, I have collected and grown some seed from the wild around Brisbane.
Can't say I have had seedlings that look exactly like those in the pics.
Also have a feeling that the leaves should be slightly more pointed than round ended.

Take a look at my website page with photos of wild Citrus australis plants growing in D'Aguilar National Park, about 50miles from Brisbane.

You will see the various different leaf forms as the plant matures. The juvenile leaves are just like yours.
