Previous theories regarding the center of origin of F. albida include that
of Chevalier ([4], cited by Wickens [13] ), who believed the species originated
in northern Africa and spread south and east. Aubrrville ([19, cited
and supported by Wickens [ 13] ) on the other hand, argued that the species
arose in the east and south near rivers and was spread by man into the
west. Neither of these hypotheses, however, were based on data from accessional
trials, or derived from examination of rangewide genetic diversity.
