Duration: Annual Nativity: Native Lifeform: Forb/Herb General: Annual herb to 33 cm tall, dioecious. Leaves: Petiolate, blades lanceolate, 3-8.5 cm long, 0.8-2.2 cm wide, attenuate at base, acute at apex, sparsely villous, distinctly 3-veined, sometimes with 2-4 widely spaced teeth. Flowers: Spikes 1.5-14.5 cm long, interrupted near base, on peduncles 0.5-3.8 cm long, sparsely to densely villous; bracts subulate to narrowly triangular to broadly triangular, 2.4-4 mm long, narrowly scarious-margined at base, ciliate; ovate sepals, 2-3 mm long, broadly scarious-margined, acute to acuminate at apex, evenly hirsute; corolla lobes erect, enclosing capsule, lanceolate, 2-3.5 mm long, 4 stamens. Fruits: Capsule breaking at middle, seeds deep red, 1-2.5 mm long, about 1 mm wide. Ecology: Found in sandy soils, often common in shrublands from 1,500-3,000 ft (457-914 m); flowers March-May. Notes: Difficult to distinguish from P. virginica, minus the unmistakable character of the red seeds. Barring fruiting structures, it is difficult to distinguish the two apart. Ethnobotany: Unknown, but other species in this genera have a variety of uses. Etymology: Plantago translates to foot-sole in reference to leaf habit on ground, while rhodosperma means red-seeded. Synonyms: None Editor: SBuckley, 2010
