America'num, (Nutt branched. Leaves ligulate. Stem flexuous, terete, glabrous, sparingly glabrous, thick; the lower ones carinate, about as long as the stern, the upper concave at the base, erect. Flow- ers in sessile, globular heads ; fertile heads 2—5, usually sessile; sterile ones 6—9. Stigma simple, oblique.— 2£. May—June. In stagnant waters. 12—15 inches. • Burr-reed. Genus II.—TY'PHA. 19—3. (From Uphos, a bog or marsh.) Flowers monoecious, collected into a long, cylindrical spike. Sterile florets : perianth wanting. Stamens united into a com- mon filament. Fertile florets : perianth none. Pericarp pedi- cellate, surrounded at the base with hairs resembling a pappus. 1. T. latifo'lia, (L.) Stem terete, glabrous. Leaves linear, nearly a9 tall as the stem, sheathing at the base. Flowers in a cylindrical spike, the upper ones sterile, the lower ones • fertile.—If. July—Aug.
