Rugel's Broad-leaved Plantain. Plantago Rugelii Decne. Seeds dark brown to black, much like those of P. major, but larger, 1.5–2.5 mm. long slightly flattened, with edges acute, very variable in shape, oval oblong, rhomboidal, surface minutely roughened and dull, but wholly without ridge or lines as in P. major. Native of this country. Lower end of leaf-stalk red, and not clear green as in P. major. A vile pest in clover fields.

Blue Field Madder. Sherardia arvensis L.

Surface dull brown, clothed with small white hairs, obovoid, 2–2.5 mm. long. Introduced from Europe, not often found in the northern states.
