Morphological variation in Altingiaceae. A Liquidambar gracilipes with obconical flattened infrutescences and short styles. Leaves are simple, entire, choriaceous, and show a characteristic drip tip at the apex B Liquidambar siamensis also shows obconical flattened infructescences with simple leaves that have a serrate margin and lack of a drip tip C Liquidambar chingii showing variation in leaf morphology from palmately three-lobed leaves at left, to two-lobed leaves and simple leaves on the same branch. Infructescences are globose with long styles D Liquidambar styraciflua showing palmately five-lobed, chartaceous leaves, and globose infructescences with long styles.
