Backyard and Beyond

Starting out from Brooklyn, an amateur naturalist explores our world.

As John Burroughs said, “The place to observe nature is where you are.”

The Other Sweetgum

Liquidambar acalycina, which iNaturalist calls Chang’s Sweetgum. These are the Burgundy Flush variety, but this has been such a rotten year for foliage. Compared to American Sweetgum, Liquidambar styraciflua, the leaves here are different, but the smaller, longer-horned seedpod is the quickest way to tell them apart.

Here again is an American Sweetgum pod.
Chang’s on the left, American on the right.
Reversed here: American on left, Chang’s on right.

  1. Thank you for the excellent detailed photos. They are very helpful in identifying the tree.

    the difference in horn length gives rise to the function of the horns. I can’t imagine their purpose, but would like to know.
