Convention On International Trade In Endangered Species

CITES Secretarial, PO Box 456,1219 Ch telaine, Geneva, Switzerland Habitat destruction is the major cause of the decline in wildlife populations, but the second most important threat is the exploitation of plants and animals (and their products) of wild origin.

Succulents are defined as plants that are able to withstand drought because of the water stored in some of their organs. They constitute a widespread group, being represented in several families of flowering plants and, to some extent, in the Gymnosperms as well.

Mokaceae Link Dicotyledons

The Moraceae family includes about 50 genera and over 1,200 species which are very diverse in habit, ranging from large trees to small herbaceous plants, usually with milky latex. Rowers are small and, in most genera, are wind pollinated. (Ficus flowers are pollinated by insects.) The flowers are grouped in inflorescences, with thickened axes forming an invaginated receptacle. The most extreme form is found in Ficus the flowers are actually inside the fig, and the pulp we eat is composed of...

Succulent Families And Genera

The families and the genera illustrated in this dictionary are described briefly in this chapter. Some reference books, most of which are monographic studies, that may be of use to interested readers are included in Further Reading. The most complete work on succulent plants is undoubtedly the three-volume A Handbook of Succulents Plants by H. Jacobsen, which covers most succulents in cultivation, although it does not include the most recent discoveries. Several periodicals specialize in...
