Unarmed herbs, shrubs or small trees. Inflorescence a terminal panicle-like cyme. Calyx 5-lobed, much shorter than the corolla tube, usually somewhat accrescent in fruit. Corolla white, yellow, pink, red or purplish; tubular with a short limb. Stamens 5; anthers included (in ours), dehiscing by longitudinal slits. Fruit a capsule with a large number of minute seeds; capsule enclosed by a persistent papery calyx.

In the nineteenth century, young tobacco plantings came under increasing attack from flea beetles (Epitrix cucumeris and/or Epitrix pubescens), causing destruction of half the United States tobacco crop in 1876. In the years afterward, many experiments were attempted and discussed to control the flea beetle. By 1880, it was discovered that replacing the branches with a frame covered by thin fabric would effectively protect plants from the beetle. This practice spread until it became ubiquitous in the 1890s.
