A Source Book Of The Genus Phytophthora PDF Download

Excerpt from Identification of Phytophthora Species The genus Phytophthora does not readily lend itself to a natural scheme of classification. Too few morphological distinctions and the too ready tendency of such distinctive lines to overlap have. Necessitated a more or less arbitrary method of classification. Consequently, there is and perhaps always will be a certain lack of permanency in our keys. As more organisms are studied and more knowledge is accumulated, certain seemingly well-established species may be discarded or new ones established.
