Gloxinia
a genus of plants, order Gesneraceæ. Some of the species are among the more popular flowers, and are well known to gardeners by their foxglove-shaped flowers of varied colors, each standing on a separate stalk-in some forms with the opening of the tube directed downward; in others standing erect. The gloxinia generate buds from fragments of their leaves, under the hands of the cultivator.
