Sporobolus pyramidatus (Lam.), Whorled Dropseed Habit: Perennial, in spreading or prostrate tufts. Culms: 10-40 cm. tall, erect or decumbent at the base, branching. Blades: Crowded at the base, mostly less than 10 cm. long, 2-4 mm. wide, often sparingly hairy at the base, the white margins scabrous. Sheaths: Shorter than the internodes, pilose at the throat. Ligule: A ring of hairs less than 1 mm. long. Inflorescence: Panicle pale, exserted, narrowly pyramidal, 3-7 cm. long or rarely longer, the branches verticillate, spreading, 1-3 cm. long, somewhat viscid, closely spikelet-bearing on the upper two thirds. Spikelets: 1-1.5 mm. long, 1-flowered, awnless, lead colored, shining, rachilla disarticulating above the glumes. Glumes: First obtuse, about 0.4 mm. long, the second acute, as long as the lemma and palea. Lemmas: About as long as the second glume, acute, 1-nerved. Palea: 2-nerved, about equaling the lemma, acute. Fruit: Grain free from the lemma and readily dropping off, pericarp loosely enclosing the seed, often thin and evanescent. Habitat: Sandy or gravelly soils, alkaline areas. April-October. Kansas Range: South central.
