Status:

Common in moist to dry woods, especially on the Coastal Plain, less common in the Piedmont, and not present in the mountains. Despite its alternate common name of "Spanish Oak," Southern Red Oak is a tree native to the southeastern United States.

Description:

A medium to tall tree. Leaves are variable but many are readily identifiable by their three, sharp, main lobes, the central one commonly quite long, narrow, and often curved (accounting for the species epithet "falcata," or sickle-shaped). Upper leaf surfaces are dark green and smooth, undersides finely hairy. Bark is dark and smooth on small and medium-sized branches, darker and shallowly fissured on large trunks. Acorns are small, with saucer-shaped cups that are tapered or funnel shaped at the base.

Relationships:

Has been recorded as a host plant for Banded Hairstreak.

Host plant to many moth species including the Buck Moth (Database of the World's Lepidopteran Hostplants).

There are 461 records in the project database.
