Deciduous, native to south-east USA and Mexico.
Deciduous trees that have a vibrant display of red seven-pointed leaves in autumn.
Known as liquid ambers here (after their gum resin), they have many other names: American sweetgum, sweet gum, hazel pine, American-storax, bilsted, red-gum, satin-walnut, star-leaved gum or alligator-wood.
Likewise the distinctive spiky fruit carries many nicknames: burr (or bir) balls, gum balls, space bugs, monkey balls, bommyknockers, sticker balls,
or goblin bombs.
Timber from these trees is highly prized in the south-eastern USA, and is called satin walnut. It is used in carpentry and as plywood veneer. The sleeping cars of railway carriages were often lined with satin walnut.
