Procimequat is a triploid citrus hybrid or transgeneric hybrid, (Citrus aurantifolia 'Mexican' x Fortunella japonica) x Fortunella hindsii, in which the limequat that itself is a cross between lime and a round kumquat, was backcrossed with the primitive Hong Kong kumquat.
The tiny fruits are orange in color, and about the size of a marble.[1] Like some kumquats, it is eaten entirely, including the peel. It tastes like a combination of lemon, orange and celery.[2]
Despite being triploid, the procimequat does produce seeds, which are nucellar[3] and thus produce plants identical to the parent, independent of the pollen source.
