Procimequat

Procimequat is a triploid citrus hybrid or transgeneric hybrid, in which the Limequat that itself is a cross between lime and a round kumquat, was backcrossed with a kumquat-like fruit, named Fortunella hindsii.

The tiny fruits are orange in color, and about the size of a marble. Like some kumquats, it is eaten entirely, including the peel. It tastes like a combination of lemon, orange and celery.

Despite being triploid, the Procimequat does produce seeds, which are nucellar. That means that it comes true from seeds, no matter on the pollen source.
