Juglans microcarpa var. "stewartii". Where the range of "J. microcarpa" overlaps with "J. major", the two species interbreed, producing populations with intermediate characteristics. This phenomenon has also been found where "J. microcarpa" trees grows near "J. nigra trees. "Juglans" (literally "Jupiter's acorn") is the Latin name of the walnut. "Microcarpa" means "having small fruit". Juglans microcarpa Juglans microcarpa, known also as the little walnut, Texas walnut, Texas black walnut or little black walnut (as it belongs to the "black walnuts" section "Juglans" sect.

Fruit tree pollination Fruit tree pollination Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma, either in the same flower or in another flower. Some tree species, including many fruit trees, do not produce fruit from self-pollination, so pollinizer trees are planted in orchards. The pollination process requires a carrier for the pollen, which can be animal, wind, or human intervention (by hand-pollination or by using a pollen sprayer). Cross pollination produces seeds with a different genetic makeup from the parent plants; such seeds may be created
