| Common Silverbell is a shrub or small tree most common in the southwestern quarter of North Carolina. Two varieties of Halesia tetraptera exist, var. tetraptera (Common Silverbell), which is a shrub or small tree mostly found along streams in the Mountains and Piedmont, and Halesia tetraptera var. monticola (Mountain Silverbell), which is a large tree of cove forests in the higher Mountains. Flower size also differs between the two varieties: var. tetraptera has smaller flowers (petals <2 cm long) with the style excerted; var. monticola has larger flowers (petals 2-3 cm long) with the style included.

| Leaf detail. The finely serrate leaves are paler and pubescent below. H. tetraptera is the only species of Halesia in NC; this species has been confused with H. carolina in older floras, such as Radford et al. Franklin, Macon Co., NC 5/13/06. |
| Unripe fruits. The four-winged fruit, technically a drupe, is dry when ripe. Since Halesia is named for a Mr. Hales, it should be pronounced Heylz'-ee-ah, though Huh-lee'-zee-ah is more commonly heard. Franklin, Macon Co., NC 5/13/06. |
