Juglans Juglans Walnut trees are any species of tree in the plant genus Juglans, the type genus of the family Juglandaceae, the seeds of which are referred to as walnuts. All species are deciduous trees, tall, with pinnate leaves , with 5–25 leaflets; the shoots have chambered pith, a character shared with the wingnuts ("Pterocarya"), but not the hickories ("Carya") in the same family. The 21 species in the genus range across the north temperate Old World from southeast Europe east to Japan, and more widely in the New World from southeast Canada west to California and south to Argentina.

Fruit of the poisonous tree Fruit of the poisonous tree Fruit of the poisonous tree is a legal metaphor in the United States used to describe evidence that is obtained illegally. The logic of the terminology is that if the source (the "tree") of the evidence or evidence itself is tainted, then anything gained (the "fruit") from it is tainted as well. The doctrine underlying the name was first described in "Silverthorne Lumber Co. v. United States", 251 U.S. 385 (1920). The term's first use was by Justice Felix Frankfurter in "Nardone v. United States" (1939). Such evidence is not generally admissible in court. For
