Among the low herbaceous and evergreen genera, the Apocyman (Indian Hemp), Amsonia, and Vinca (Periwinkle), are common border ornamental plants. Propagated by cuttings and divisions of the clumps or stools in spring. AroidecB or Araceee (Arum Family).—A large order of herbaceous perennial plants with tuberous rhizomes. The most familiar genera in cultivation are Aloeasia, AmorpJiophaUus, Anthurium, Caladium, Coloca- sia (Tanya), Diffenbachia, and Richardia (Calla). The flowers are very minute, unisexual or perfect, produced on a central organ called a spa- dix, and this surrounded by a large spathe, which is sometimes—as in the AmmphaphdOMS .Bij««rt—two feet or more in diameter, and emiting ».

The rhizomes of some of the genera contain an acrid watery juice, as in the wild Indian Turnip {Ariscema), while in others, such as the Oolocasia esculenta, they are edible when cooked. This edible species is known in oiir Southern States, where it has become naturalized, as the Tanya. It is largely employed as a bedding-out plant in the Northern States, the leaves growing to an immense size, and the general habit and form of the plant is shown in figure 105. The Richardia or Calla Lily, as it is called, is a well-known and common window and greenhouse plant. The Caladiums are what may be termed hot-house plants, requiring a high temperature and moist atmosphere to insure the full development of their billliant colored and h
