Genus Identification: Identification notes: Seedlings and fire sprouts are superficially very similar to Nyssa sylvatica, but can be separated in the following ways: bundle scar 1 per bud scar, narrowly crescent-shaped (vs. Nyssa with 3 distinct, circular, bundle scars arranged in a broad V pattern), leaves never with teeth (vs. Nyssa leaves sometimes with a few irregular teeth), leaves glabrate to tomentose with curly hairs (vs. glabrous or with a few straight, forward-pointing hairs), leaves with sessile to short-stipitate glands on upper surface of midrib and outer petiole, later becoming necrotic spots (vs. leaves without glands).
