The first Flora specific to Israel and surrounding areas. Its four parts, each comprising one volume of text and one of plates, treat some 2,470 species to be found at this meeting point of four phytogeographical regions. Many of the species and varieties included are described here for the first time or renamed since the second edition of Post's Flora. The descriptions, with few exceptions, are based on plants deposited in the Herbarium of the Hebrew University of Jerusalem.
