{{Unreferenced section|date=January 2024}}
It is a shrub growing to 1–2 m tall and to 3 m or more broad, with opposite simple leaves 3–7 cm long and 2–5 cm broad, with a serrated margin and a crinkled surface. The flowers are produced in erect terminal panicles, each flower white, 15–20 mm diameter, with five (rarely four) petals. The fruit is a dry capsule with numerous small seeds.
Etymology
The genus is named in honor of Edwin James, the botanist on Stephen Long's expedition in 1820 that explored the territory between the Platte and Arkansas Rivers. James was the first to collect this genus for botanical study.Fertig, USDA
