Dracaena (romanized form of the Ancient Greek δράκαινα - drakaina, "female dragon") is a genus of about 40 species of trees and succulent shrubs classified in the family Ruscaceae in the APG II system, or, according to some treatments, separated (sometimes with Cordyline) into a family of their own, Dracaenaceae or in the Agavaceae. Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Liliopsida is a Botanical name for the class containing the family Liliaceae (or Lily Family Asparagales is an order of Flowering plants The order must include the family Asparagaceae, but other families included in the order have varied markedly Ruscaceae is a family of Flowering plants in the order Asparagales that includes several genera previously included in the Liliaceae, for example in Domenico Agostino Vandelli (c 1735 - June 27, 1816) was an Italian naturalist.

The segregate genus Pleomele is now generally included in Dracaena. The genus Sanseviera is closely related, and has recently been synonymized under Dracaena in the Kubitzki system. Sansevieria (mother-in-law's tongue is a genus of about 70 species of Flowering plants in the family Ruscaceae, native to tropical and subtropical regions A system of plant taxonomy, the Kubitzki system was published in The system is important as being a comprehensive multivolume treatment of the

Dracaena have a secondary thickening meristem in their trunk. A meristem is a tissue in all Plants consisting of undifferentiated cells ( meristematic cells) and found in zones of the plant where growth can take place This monocotyledonous secondary thickening meristem is quite different from the thickening meristem found in dicotyledonous plants and is termed Dracaenoid thickening by some authors. Monocotyledons or monocots are one of two major groups of Flowering plants (angiosperms that are traditionally recognised the other being Dicotyledons Dicotyledons, or "dicots", is a name for a group of Flowering plants whose Seed typically has two embryonic leaves or Cotyledons There This character is shared with other members of the Agavaceae and Xanthorrhoeaceae among other related families. Agavaceae is a family of Plants that includes many well-known Desert and dry zone types such as the Agave, Yucca, and Joshua Xanthorrhoeaceae is the Botanical name of a family of Flowering plants.

They can be divided into two groups based on their growth habits:

  1. A group of tree-size species with stout trunks and stiff, broad-based leaves, growing in arid semi-desert areas, and known as dragon trees. A desert is a Landscape or region that receives very little precipitation.
  2. A group of smaller, shrubby species with slender stems and flexible strap-shaped leaves, growing as understorey plants in rainforests (and very popular as houseplants), and known collectively as shrubby dracaenas. Rainforests are Forests characterized by high Rainfall with definitions setting minimum normal annual rainfall between 1750–2000 mm (68-78 inches

Several other species previously included in Dracaena are now treated in the genus Cordyline. Dracaena draco, the Canary Islands Dragon Tree or Drago is a subtropical Dragon Tree native to the Canary Islands, Cape Dracaena fragrans ( Corn Plant Cornstalk Dracaena) is a Flowering plant Species in the family Ruscaceae, that resembles Dracaena marginata (Madagascar Dragon Tree or Red Edged Dracaena is a Flowering plant in the family Ruscaceae, native to Madagascar. Dracaena reflexa, commonly called Pleomele or the Song of India, is a Species of Dracaena (family Ruscaceae Dracaena sanderiana, known as Ribbon Dracaena, Lucky Bamboo, Belgian Evergreen or sometimes Ribbon Plant, is a species of Cordyline is a Genus of about 15 species of woody Monocotyledonous Flowering plants classified in Asparagaceae or alternatively

Uses

A bright red resin, dragon's blood, is produced from D. Dragon's blood is a bright red Resin that is obtained from different species of four distinct plant genera Croton, Dracaena, draco and, in ancient times, from D. cinnabari. Some species such as D. deremnsis, D. fragrans, D. godseffiana, D. marginata, and D. sanderiana are popular as houseplants. Rooted stem cuttings of D. sanderiana are widely marketed in the U. S. A. as "Lucky Bamboo", although only superficially resembling true bamboos. Bamboo is a group of Woody perennial Evergreen Plants in the True grass family Poaceae, subfamily
