Abstract

Flowers from 15 species of the genus Dalea (Leguminosae) were cleared and stained. Complete isolation of the xylem of the gynoecium, androecium and corolla from the pedicel xylem was found except in two species. The most obvious feature was the "discontinuity plate" formed by the merger of the xylem of the gynoecial traces in a characteristic mass of tracheoidal cells near the base of the flower. Variation in the floral vascular pattern appears to have taxonomic implications.
