The arborescent taxa of Dracaena which form the dragon tree group comprise five species found in Macaronesia, Morocco D. A new species of dragon tree, Dracaena tamaranae A. Marrero, R. This new species differs from D. In contrast, D. In this paper, we also present a study of the taxonomy, habitat and ecology of all the species of the dragon tree group.

These are found in thermo-sclerophyllous plant communities of tropical-subtropical regions which are rather xerophilous and have a rainfall range of — mm. Our study indicates two independent colonization events for Dracaena in Macaronesia. In addition, we suggest that the dragon tree group provides an example of two major biogeographical disjunctions between East and West Africa.

We postulate that this group has a Tethyan origin, a hypothesis supported by fossil and palaeoclimatic data, and thus parallels the distribution and dispersal pattern of other taxonomic groups. Acta Botanica Academiae Scientiarum Hungaricae 14 , 3—4 — III Compositae—Gramineae.

Dracaena tamaranae

Dracaena draco , the Canary Islands dragon tree or drago , [3] is a subtropical tree in the genus Dracaena , native to the Canary Islands, Cape Verde, Madeira, and locally in western Morocco, and introduced to the Azores. It is the natural symbol of the island of Tenerife , together with the blue chaffinch. Dracaena draco is a monocot with a branching growth pattern currently placed in the asparagus family Asparagaceae , subfamily Nolinoidae. At about 10—15 years of age the stem stops growing and produces a first flower spike with white, lily-like perfumed flowers, followed by coral berries. Soon a crown of terminal buds appears and the plant starts branching. Each branch grows for about 10—15 years and re-branches, so a mature plant has an umbrella-like habit.
