Calliandra calothyrsus: implications of plant taxonomy, ecology and biology for seed collection.
The importance of Calliandra calothyrsus in agroforestry throughout the tropics is described. Information on the species taxonomy, habit, ecological amplitude, and reproductive biology is presented and implications for the seed collection strategy are discussed. Guidelines for sampling are included and the process of provenance delimitation is described. Specific details including topographical, political, climatic, edaphic and ecological maps of the provenance sites are given. The ability to achieve real improvement in species performance is discussed in relation to the perceived potential and limitations of the species in agroforestry systems. Authors' summary.
