I was checking some of the seeds I'm germinating, and look! This orange seed is polyembryonic!
Polyembryonic seeds are basically what happens when a plant has twins, and one seed contains more than one embryo. Some plants (like some types of mango) always grow seeds like this. In my experience, it's unusual in oranges though.
Cool, I found a botany paper about this. Apparently, some citrus cultivars have a habit of producing these polyembryonic seeds.

@InvaderXan I just wanted to mess around with growing citrus, and for some reason no one in this area sells oranges or limes with seeds. I do like grapefruit, though, so it's all fine in the end.
Oh, that’s funny. Though I’ve had similar trouble finding limes with seeds in some places. My go to option is lemons. Not sure I’ve ever found a seedless lemon. 🍋
