From the Introduction:  "The range of citrus is enormous.  The hundreds of varieties and subspecies make it the most commonly propagated fruit, cultivated commercially in over 100 countries.  Because the yield of the average citrus tree far exceeds that of any deciduous tree (such as apple, pear, peach or plum), citrus is an economic mainstay for many countries.  The hybridization (crossbreed) process has made citrus one of the most complex fruits on earth.  This book will help you discover more exotic species---as well as learn more about the everyday orange."

Contents:  The genus citrus - with descriptive histories of 8 species, as well as known varieties with colored photos, The genus fortunella (kumquat), Unusual citrus & root stock fruits, Recipes, Citrus of the World Index.
