Bibliographic record
Abstract
culms of this tufted perennial grass are erect, 28 to 59 in. (70 to 150 cm) tall, often grooved above the nodes, and hairless. The ligules are up to in. (0.5 to 2.7 mm) long, jagged edged and hairy margined. The blades are flat or folded, 1/16 to in. (1.5 to 6 mm) broad, and hairless to rough hairy above. The margins of the blades have short, stiff hairs. The inflorescence is paniculate, with racemes of spikelets borne at the ends of each panicle branch. The spikelets are born in twos at the nodes: one sessile and one pedicellate. The pedicellate spikelet is 1/8 to in. (4 to 5 mm) long. The sessile spikelet is 1/8 (4 to 7.5 mm) long. The glumes of the sessile spikelet are usually nearly equal, covered with rough, stiff trichomes on the lower half, or mostly hairless. The first glume is 5 to 7 nerved with the margins folded inward, clasping the second glume. The second glume is keeled and 3-nerved. Each spikelet is 2-flowered, with one fertile floret and one empty floret. The fertile lemma is 1/8 to in. (4.2 to 6.5 mm) long, bearing an awn that is abruptly bent at the joint, to in. (6 to 16 mm) long and usually twisted below. Identification Tips: There is only one species of Schizachyrium in the Pacific Northwest. It blooms quite late compared to most perennial grasses, but can be distinguished at the vegetative stage by its strongly reddish cast. Phenology: This taxon is generally identifiable from July through September. Range: Schizachyrium scoparium can be found from Alberta to

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
