Plate XXV. Tall Meadow Rue - T. polygamum

Where a stream trails its sluggish length through the fields of midsummer, its way is oftentimes marked by the tall meadow rue, the feathery, graceful flower-clusters of which erect themselves serenely above the myriad blossoms which are making radiant the wet meadows at this season. For here, too, we may search for the purple flag and fringed orchis, the yellow meadow lily, the pink swamp milkweed, each charming in its way, but none with the cool chaste beauty of the meadow rue. The staminate flowers of this plant are especially delicate and feathery.
