Abstract
Karyomorphology ofCoriaria, the only genus of the family which is controversial with respect to its affinities and the number of constituting species, is investigated on the basis of ten species (including eight narrowly defined species) representing nearly all the variation of the genus. Features common to all the species investigated are: (1) interphase nucleus has a few small or large, condensed heterochromatic blocks; (2) chromosomes at metaphase are mostly small (0.4–0.7 μm long by our methods); (3)x=20. Resemblances in chromosome morphology suggest that Coriariaceae may have affinities with Rutales/Sapindales. Differences among species are found in (1) whether somatic chromosomes are diploid (2n=40) or tetraploid (2n=80); (2) the presence or absence of a few chromosomes with thick heterochromatic segments at metaphase; when such chromosomes are present, (3) their number and (4) morphology. Karyomorphology defines wellCoriaria myrtifolia, C. napalensis andC. japonica, and further provides evidence for distinguishing at least four species withinC. ruscifolia sensu Skog.
