Leaves ovate, rhombic-ovate or the upper lanceolate, slender-petioled, acute at both ends, 1-3' long, with a pair of rigid stipular spines i'-i' long at each node, the midvein excurrent; flowers monoecious, the pistillate in numerous capitate axillary clusters, mostly shorter than the petioles, the staminate in dense terminal linear-cylindric spreading or droop- ing spikes i'-6' long; bracts lanceolate-subulate about as long as the 5 scarious oblong mucronate- tipped i-nerved sepals, and the thin imperfectly cir- cumscissile utricle; stamens 5.

Nearly or quite glabrous, rather pale green, stem diffusely branched, prostrate and spreading on the gorund, ridged, 6'-2° long, often forming mats. Leaves obovate or spatulate, i'-i' long, obtuse or acute at the apex, narrowed into slender petioles, sometimes longer than the blades; flowers polyg- amous, in small axillary clusters mostly shorter than the petioles; bracts oblong to lanceolate-subulate, little longer than the 3 to 5 oblong-lanceolate acute or cuspidate sepals; stamens 3; utricle nearly smooth, circumscissile, equalling or slightly longer than the sepals. In waste places, especially along the principal routes of travel, Maine to southern Ontario and North Dakota, sout
