Vanilla Tahitensis

Vanilla tahitensis (aka Vanilla x tahitensis) is a natural hybrid between two vanilla species. A long time ago, an insect pollinator (maybe a bee) carried pollen from a V. odorata flower and transferred it to a V. planifolia flower. The bean ripened and seeds eventually grew from that bean resulting in what we call Vanilla x tahitensis (the "x" means it's a hybrid).
