Résumé
The Casuarinaceae family includes about eighty species of shrubs and trees belonging to four genera, namely: Allocasuarina, Casuarina, Ceuthostoma, and Gymnostoma. Casuarinaceae are primarily native to the Southern Hemisphere, mostly Australia and Indo-Pacific areas, from Malaysia to Polynesia. However, the range of distribution of some genera such as Casuarina has been extended considerably through artificial dissemination. All members of the family are characterized by highly reduced leaves and photosynthetic deciduous branchlets (Midgley et al., 1983; National Research Council, 1984).
