Muhlenbergia racemosa (Michx.) Green Muhly Habit: Perennial, from stout creeping scaly rhizomes. Culms: Erect or reclining 50-100 cm. tall, simple or sparingly branched, smooth or rough below the panicle and the nodes. Blades: Flat, mostly appressed, 5-12 cm. long, 2-6 mm. wide, scabrous. Sheaths: Shorter than the internodes, or those of the branches overlapping. Ligules: Erose-truncate, 1 mm. long. Inflorescence: Narrow, compact or lobed, bristly panicle 3-10 cm. long, erect or slightly nodding, the branches rather distinct, overlapping. Spikelets: 4-6 mm. long, much crowded, subsessile, 1-flowered, flower perfect, rachilla disarticulating above the glumes. Glumes: Including the awn 4-6 mm. long, subequal, scabrous on the keel at least, stiffly awntipped. Lemmas: About 3 mm. long, one half to two thirds as long as the glumes, acuminate to awn-pointed, pilose below, scabrous above, the 3-nerves prominent. Palea: Thin, subequal, nearly equal to the lemma. Fruit: Grain closely enveloped by the lemma. Kansas Range: Except southwest and southeast. Remarks: The largest of our Muhlenbergias.
