These fruit started falling last week. They are approx. 2cm and seedless, so probably undersized this year, due to non pollination.
They probably tend to develop a more yellow skin, if they drop and sit about for a while.
I thought they tasted like a mix of very mild orange, with a kick of something else lime- like, but without any true lime flavor.
My Wife said they were so sour she couldn't taste anything !

Nicely done pic. Very Informative.

Can you share seed?

I grew these from seed, but they dont seem to be producing seed themselves. Probably not pollinated.If you search this forums old posts, I think you will find some USA sources of Microcitrus.

Thank you!!!
