Gun tree is the common name for the genus "Eucalyptus".
Despite its name, no species of gum tree, or eucalyptus, is used in making gum. The "Chewing Gum tree" is the nickname for the Sapodilla tree, which is native to Central and South America. Chewing gum is made from a thick, milky, latex juice called "chicle" which is extracted from the sap of the sapodilla tree.
The sweet gum tree gets its name from the aromatic resin it produces, which has a sweet fragrance reminiscent of gum. This resin, known as "gum" or "balsam," exudes from wounds in the bark and was historically used for medicinal purposes and as a chewing gum. The tree's scientific name, Liquidambar styraciflua, also reflects its gum-producing properties.
