. Contributions from the Botanical Laboratory and the Morris Arboretum of the University of Pennsylvania, vol. 13. Botany; Botany. 324 Rhodora [September Ij m fruit), each with a pair of inconspicuous bracteoles at the base 1^ lower-bracts leafy-ovate below, lanceolate or linear above, little longer than the pedicel, finely callose-denticulate, smooth or ciliate Calyx in anthesis campanulate, smooth, becoming much inflated in fruit, oval to sub-globose, X mm. Capsule inferior. Calyx-lobes subulate or linear, () mm. long, smooth or rarely slightly ciliate; auricles none. Flower inconspicuous, 8-10 mm long, including calyx. (In this species the corolla is quite short in proportion to the calyx, being only about 7 mm. long.) Corolla violet-blue to nearly white, sometimes with a suggestion of pink which shows plainly m dried material; base of the lower lip pubescent- corolla otherwise smooth. Corolla-tube entire, except for the dorsal lissure; lobes of the lower lip oblong, shorter than the tube; the two upper lanceolate. Filament-tube mm. long, slightly pubescent below, united % of its length above. Anther-tube mm. long bluish-gray, the two smaller anthers tufted at the tip, the three larger merely pubescent on the backs. Annual. This species is readily identified in flower by the campanulate calyx rather long calyx-lobes, and the short corolla, which seems even shorter in proportion to the large calyx. Flowering specimens are sometimes mistaken for L. spicata, as the branches often do not develop until frmt has appeared on the main axis. Fruit matures quickly, so that a single plant is in flower during a long period and still has only a few flowers open at a time, instead of the long flower spike of L. spicata.—Dry woods, fields, roadsides and waste places- an aggressive, weedy species.
