Fig 173. [Rib-Grass. Narrow-leaved Plantain. Plantago lanceolata L.]

Rib-Grass. Narrow-leaved Plantain. Plantago lanceolata L. Seeds shining, amber-colored to brown, oval, 2–2.5 mm. long, shaped like a shallow, thick-walled canoe with ends rounded alike, a dark scar occupying the middle of the narrow concave side, a faint, transverse groove across the convex side near the middle sometimes apparent. Often found mixed with clover seeds from which it is very difficult to separate. Introduced from Europe.

Fig 174. [Broad-leaved Plantain. Plantago major] L.

Broad-leaved Plantain. Plantago major L. Seeds, light to dark brown or very nearly black, 1–1.5 mm. long, slightly flattened, with acute edges very variable in shape, oval, oblong, rhomboidal and trapezoid, the surface roughened by slender, colored ridges, appearing under the lens as slightly wavy lines, radiating from the scar. The clear light green color of the lower end of the leaf-stem is an easy mark to distinguish this plant from another broad-leaved plantain, P. Rugelii in which the base of leaf is red. Introduced from Europe. About door yards.
