This paper-back book of 280 double-column pages is one of the first to provide an easy way to recognize the common plants of the extremely diversified flora of Mexico. Tourists on Mexican highways are bewildered by the great number of unfamiliar trees, shrubs, and herbs they see. Since Mexico has just about all climates from perpetual snow on mountain tops to tropical heat along the coasts, habitats are provided for an enormously large number of species.
