Botany
Halesia (tetraptera var.) monticola, the mountain silverbell, is a species of flowering plant in the small family Styracaceae. This large deciduous shrub was originally included in H. carolina, but was identified first as a subspecies by Rehder in 1914 and then as a species by Sargent in 1921. More recently, some authoritative sources regard it only as a subspecies or variety, while other authoritative sources regard it as a species, as it is treated here.
