dracaena

American Heritage® Dictionary of the English Language, Fourth Edition

1. n. Any of several tropical plants of the genera Dracaena and Cordyline, some species of which are cultivated as house plants for their decorative foliage.

Century Dictionary and Cyclopedia

1. n. A genus of liliaceous trees, natives of the tropical regions of Africa, Asia, and Polynesia, including about 35 species. The leaves are large, lanceolate, and entire, often somewhat fleshy, and are borne in tufts at the ends of the branches. The flowers are small and the fruit is baccate. Various species are cultivated in greenhouses and in ornamental grounds on account of their foliage and tropical habit, though some that are known under the name belong rather to the related genus Cordyline. The most remarkable species is the dragon-tree, D. Draco, of the Canary islands, which yields a resin called dragon's-blood. It is of rapid growth, and attains sometimes a gigantic size. A famous tree at Orotava, on Teneriffe, which was destroyed by a hurricane in 1867, was about 75 feet high and 79 feet in circumference near the base, and was of nearly the same size in 1402.
