The calyx is small, four-toothed and persistent; the corolla salver-shaped with a long tube and four limb segments; the stamens two, sessile in the corollatube; the style bifid and included; and the fruit, n two-chambered, four-seeded capsule. There are numerous slight variations in cultivation, and 8. Josikaa from Transylvania has flowers which, very unlike those of the other forms, are scentless.
