Upper lip of the corolla ob- long, entire; the lower little shorter, erect, 2-plaited, with 3 very short and broad ebtuse lobes. Anther-cells parallel. Capsule ovate. Seeds linear, with a loose chaff-like coat. — A perennial minutely pubescent upright herb, 3-6 dm. high, with leafy simple stems terminated by a loose spike of rather large dull purplish-yellow flowers ; leaves alternate, sessile, 3-nerved, entire, ovate or ob- long, the upper gradually reduced to narrow bracts; pedicels very short, with 2 bractlets under the calyx. (Dedicated to C G. Schwalbe, an obscure German botanist.) 1. S. americina L. — Wet sandy soil, Mass. to La., near the coast. May- July. LENTIBULARlACEAE (Bladderwort Family) Small herbs {growing in toater or wet places), loith a 2-lipped calyx, and a 2- lipped personate corolla, 2 stamens with {confluently) 1-celled anthers, and a 1-celled ovary with a free central placenta, bearing several anatropous seeds, with a thick straight embryo, and no albumen. Corolla deeply 2-lipped; the lower lip larger, 3-lobed and with a prominent palate, spurred at the base in front; the palate usually bearded. Ovary free ; style very short or none ; stigma 1-2-lipped. Capsule often bursting irregularly. Scapes 1-few-flowered.—The following are the two principal genera. 1. «Utricularia. Calyx-lobes mostly entire. Upper lip of corolla erect. Filaments strongly incurved. Foliage usually dissected, bladder-bearing. 2, Pinguicula. Calyx with upper lip deeply 3- and lower 2-cleft. Corolla-lobes spreading. Fila- ments straighter. Terrestrial, with entire rosulate leaves next the ground. 1. UTRICTTLArIA L. B
