I'm trying to find out what kind of tree this leaf coming from.
Where is this tree located, is it wild or in a garden, have you seen it bloom, how tall, can you show a picture of the whole thing ... lots more details would be helpful.
My dad planted it from a seed but not sure what but a fruit tree for sure. it is only one foot tall now.
And where is it located? United States, elsewhere? If US, what state?
Citrus trifoliata ?
What is the scale of the picture? The texture of the leaf stalk doesn't really look like a tree leaf. On Citrus trifoliata there isn't such a disparity in size between the terminal leaflet and the other two imo.
A picture of the whole plant would be really helpful.
Agreed on leaf. But it was my best guess. The leaflets individually look like a Ceratonia siliqua, round with notch at tip. But I can't figure this, yet.
