RIB-GRASS, BUCKHORN, ENGLISH PLANTAIN.. b Fig. 27.—Seeds of rib-grass (Pl<ui- tago lanceolata): a, front and back views of seeds; b, natural size of seeds. Seeds oval-oblong, If-3 mm. long, flattened, one face convex, the other having a deep groove and rounded, infolded edges which scarcely meet at one end; surface smooth or slightly uneven, shining in fresh seed, brown or somewhat amber-colored; scar situated at the center of the grooved face; embryo straight, in the center of the endosperm, usually evident through the somewhat transparent endosperm and seed coat. When placed in water the seeds develop a coat of transparent mucilage. (Fig. 27.)
