There are many flower types in Gesneria, but most of the species readily available in horticulture are characterized by red tubular flowers and rosette habits (e.g., G. reticulata and G. cuneifolia). The shrub habit of Gesneria is rare in cultivation, and the flowers of these species are not typical of material that is more readily available in cultivation. Many shrubs of Gesneria have campanulate (bell-shaped) flowers that are coriaceous (leathery). The outer surface of the shrubby species’ flowers appears waxy because they are covered with resin deposits (Fig. 3). A selection of campanulate corollas with resin deposits is featured in Figure 3. Another character of many Gesneria flowers is the presence of fimbriations along the margins of the corolla lobes (Figs. 2B, F & H).
