The large basal leaves are sometimes more than two feet in length, oblong lance-shaped, broadening above the base, smooth but with thick ribs and veins and long petioles; stem leaves long- pointed and much smaller. Panicle very large and dense, sometimes nearly two feet in length, its branches nearly erect, often with leafy bracts among the whorled flowers. These are small and green with six sepals, six stamens and three styles, the calyx differing from that of the following species in that only one of the three enlarged, heart-shaped, veiny inner sepals or valves has a small tubercle on its back, or sometimes merely a thickening of the base of its midrib.
