Poaceae is a large monocotyledonous plant family encompassing the true grasses, characterized by herbaceous, often culm-forming stems with hollow internodes, leaves composed of sheaths, ligules, and linear blades, and a distinctive inflorescence of spikelets bearing reduced, wind-pollinated florets. Flowers are typically subtended by glumes and lemmas, with lodicules facilitating anthesis, and produce single-seeded dry fruits (caryopses) in which the seed coat is fused to the pericarp. Poaceae exhibits C3, C4, and intermediate photosynthetic pathways, occupies diverse terrestrial habitats worldwide, and plays central roles in primary productivity, biogeochemical cycling, and the evolution of grass-dominated ecosystems.
Harvesting tall fescue above annual bluegrass seed heads could help reduce contamination and seed-cleaning costs. Preliminary Oregon research found that cutting at 28 centimeters (11 inches) rather than 5 centimeters (2 inches) ...

When a 10,000-year-old prairie is plowed up to plant corn or a savanna is consumed by a strip mall, these once-grassy expanses, if left to regrow, can eventually look vaguely like they did before. But a growing body of research ...
