I might add these are much smaller than oranges kinda like the size of Halos. The skin is very smooth. It tastes like very sweet Navel orange.

There are several 'trunks' I didnt see an actual stump where it could have been cut. I suppose it could be coming from roots or an underground stump. It could be a group of seedlings, I suppose lol. We have never seen fruit back there in the 5 years we have lived here and seedlings take 6 yrs or so to fruit.

I’d guess it’s a mandarin seedling.

Clearly some sort of mandarin, most likely a Satsuma

Thanks you guys! I have an Owari Satsuma but the fruit shaped differently than this. This one is round but is kinda flattened on both the ends. The skin is really smooth. I went out and dug around the bottom of the trunks. They were buried under a bunch of leaves and stuff, and I did find a place that was cut or broke off like maybe someone originally cut a tree down. So if these are suckers, the original tree must not have been grafted or it would be a sour orange right? and these are definitely not sour at all.

I took some pics of the tree before it got dark tonight. The trees around it have lost their leaves for the winter so it shows up now. It is tall and skinny about 10ft. It was trying to reach for light most of the year, I guess. Normally, the citrus blends in and was hidden in the 'thicket' of green lol.

Since the fruit is so good, I plan to cut these other 2 trees down (on the left and right of the green leafed area) that are shading the citrus out.

I need help figuring out what to do with the "trunks"..just leave them or thin it to one or two?

The whole citrus tree (the green part) you can't see the trnks from here.

The bottom where I uncovered the leaves and soil.

Side of the bottom..all those trunks come from the base...I think..

Close up of the leaves

I had to look up what a Changsha was. It does sound like it could be that or something very similar. I read that the stems could be thorny and some of these are. It also said the fruit didn't have very many seeds but these were very seedy though. They had like 2 to 3 seeds per segment. They were so good that I totally forgive that :)

What a lucky find!!! Take care of that tree regardless of its official name...sounds delicious! Enjoy.

Changsha tangerines are known for being seedy. I believe you have a Changsha

Thank Laura. I plan to :) Hopefully I can figure out what to do with the trunk area and get it cleaned up. There is a thorny green vine growing all through that area as well that does not look fun to clear out lol.

poncirusguy, thanks for the ID! It sure is good I feel like today was my lucky day lol. Plus, I learned what a Changsha is. I read it is extemely cold hardy so that is a big plus since I am in NE FL and we have got into the teens before although some years we don't freeze at all.

I agree with Poncirusguy sounds like a changsha.

That is so cool... to find a mature, already fruiting one, with delicious fruit on it.

Could be Changsha or just any old seedling from a mandarin.

Regardless of what it is, it sounds and looks delicious! That is a nice, very hardy tree which we would all love to be able to grow in our yards! Nice find! :)
