Leaves usually solitary, 8'-4° long, pedately divided into 5-17 segments, much longer than the scape; segments obovate or oblong, 3'-io' long, 9"-4' wide, abruptly acute at the apex, narrowed to a sessile or nearly sessile base, entire or the lateral ones somewhat lobed; scape sheathed by membranous scales at the base; spathe greenish or whitish, narrowly convolute, acuminate, 1-2' long, enwrapping the spadix, the upper part of which tapers into a slender appendage exserted 1-7' beyond its apex; inflorescence of the staminate plant nearly as long as the tubular part of the spathe; in the monoecious plant the pistillate flowers are borne on the lower part of the spadix; ovary turbinate, with 6-8 bottle-shaped ovules; stigmas depressed; berries reddish-orange in large ovoid heads. Mostly in wet woods and along streams, but sometimes in dry soil, Maine to Ontario and Minnesota, south to Florida, Kansas and Texas. May-June. 2. PELTANDRA Raf. Journ. Phys. 89: 103. 1819. Bog- herbs, with entire sagittate acute or acuminate leaves, the long petioles sheathing the shorter scape at the base. Spathe elongated, convolute, or expanded above. Flowers monoecious, covering the whole spadix. ' Perianth none. Staminate flowers uppermost, consisting at first of irregularly 4-sided oblong flat-topped shields, from the edges of which appear 6-10 imbedded anthers opening by apical pores, the shields ultimately shrivelling and leaving the linear-oblong anthers nearly free. Ovaries ovoid, surrounded at base by 4 or 5 white fleshy scale-like staminodia, i-celled; ovules solitary
