S ummary Angiospermic families are considered by the author as distinct evolutionary sets, directly issued by sexual segregation from the vegetative proliferation of green matter which covered Earth by the end of the Mesozoic geological period. These family sets may, and consequently must, all be fitted to a common mathematical scheme, made of a Mendelian trinomial expansion through successive, interdependent but independent, evolutionary periods in each of which has become segregately fixed a functional character. So all taxa are precisely located by means of a discontinuous numeration, whose gaps, substitute to missing links, measure dissimilarity between the actually existing forms. This discontinuity can also be translated in cartesian coordinates corresponding to morphological degree of adaptative specialization (+ or − x ), simplifying involution ( y ), recessive diversion ( z ). Families then can easily be compared, for each of their evolutionary periods as well as in totality, inside the standard, mathematical or graphical, scheme in which is expressed the comparative pressure of past and present environmental conditions.
