PEACH TREE Prunus persica
Thousands of years before Wilson's time, China was exporting many of its
botanical treasures, and the peach tree is a prime example. Its species name,
persica, springs from the mistaken belief among European naturalists
that the plant was native to Persia. In fact, botanists now think that peaches
were introduced to the Middle East and Mediterranean regions along the Silk
Road as long ago as 2000 B.C. Other flowering trees with edible fruits,
including oranges, may have traveled a similar path.
