## Abstract

A new and distinct variety of Pinus thunbergiana tree (popularly known as Japanese black pine). A specifically selected, genetically superior plant which is able to absorb more iron from the soil than other seedlings of Pinus thunbergiana resulting in a more uniform green color of the needles. Another distinguishing characteristic of this selection is the absence of needle tip burn (or browning) associated with smog.

## Claims
