in botany, a genus of the hexandra monogyria clasps. The corolla is tunnel-shaped, the filaments are inserted into the base of the petals; and the capsule consists of three cells. There are only three species of the aletris, viz. the farinosa, a native of America; the capensis, a native of the Cape of Good Hope; and the fragrans, a native of Africa. The two first are perennial plants, and the last is a fruit-bearing shrub. These are all ranked among the aloes of different authors. See Aloe.
