This volume - the first of this series dealing with angiosperms -
comprises the treatments of 73 families, representing three major
blocks of the dicotyledons: magnoliids, centrosperms, and
hamamelids. These blocks are generally recognized as subclasses in
modern textbooks and works of reference. We consider them a
convenient means for structuring the hundreds of di cotyledon
families, but are far from taking them at face value for
biological, let alone mono phyletic entities. Angiosperm taxa above
the rank of family are little consolidated, as is easily seen when
comparing various modern classifications. Genera and families, in
contrast, are comparatively stable units -and they are important in
practical terms. The genus is the taxon most frequently recognized
as a distinct entity even by the layman, and generic names provide
the key to all in formation available about plants. The family is,
as a rule, homogeneous enough to conve niently summarize biological
information, yet comprehensive enough to avoid excessive re
dundance. The emphasis in this series is, therefore, primarily on
families and genera.
