'''Sweetgum''' (''Liquidambar'') is a genus of four species of [[flowering plant]]s in the family [[Altingiaceae]], though formerly often treated in the [[Hamamelidaceae]]. They are all large, [[deciduous]] [[tree]]s, 25-40 m tall, with [[leaf shape|palmate]]ly lobed [[leaf|leaves]] arranged spirally on the stems. The [[flower]]s are small, produced in a dense globular [[inflorescence]] 1-2 cm diameter, pendulous on a 3-7 cm stem. The [[fruit]] is a woody multiple [[capsule (fruit)|capsule]] 2-4 cm diameter (popularly called a "gumball"), containing numerous [[seed]]s.<br />
<br />
;Species<br />
*''[[Liquidambar acalycina]]'' - Chang's Sweetgum (central & southern [[China]])<br />
*''[[Liquidambar formosana]]'' - [[Chinese Sweetgum]] (central & southern [[China]], southern [[Korea]], [[Taiwan]], [[Laos]], northern [[Vietnam]]).<br />
*''[[Liquidambar orientalis]]'' - [[Oriental Sweetgum]] or [[Turkish Sweetgum]] (southwest [[Turkey]], [[Greece]]: [[Rhodes]]).<br />
*''[[Liquidambar styraciflua]]'' - American Sweetgum (eastern [[North America]] from [[New York (state)|New York]] to [[Texas]] and also eastern [[Mexico]] to [[Guatemala]]).<br />
<br />
The genus was much more widespread in the [[Tertiary]], but has disappeared from [[Europe]] due to extensive [[glaciation]] in the north and the [[Alps]], which has served as a blockade against southward migration. It has also disappeared from western [[North America]] due to climate change, and also from the unglaciated (but nowadays too cold) [[Russian Far East]]. There are several [[fossil]] species of ''Liquidambar'', showing its [[relict]] status today.<br />
<br />
===Uses===<br />
The wood is used for furniture, interior finish, paper pulp, veneers and baskets of all kinds. The heartwood once was in furniture, sometimes as imitation mahogany or circassian walnut. It is used widely today in flake and strand boards. Sweetgum is a foodplant for various [[Lepidoptera]] [[caterpillar]]s, such as the [[gypsy moth]].<br />
