Carex sychnocephala many-headed sedge Status: State Sensitive
Bibliographic record
Abstract
tufted, without creeping rhizomes. Culms slender, 2 to 20 inches tall aphyllopodic. Leaves flat or nearly so, <1/16 to 1/8 inch wide, few but well scattered, the upper often surpassing the culms. Spikes several gynaecandrous, sessile, closely crowded in a dense, ellipsoid or ovoid head 2/3 to 1 inch long, light green or greenish-stramineous in aspect. Bracts sheathless, one or more of the lower ones much enlarged and foliaceous, 3 to 8 inches long, the spikes thus appearing to be surrounded and much surpassed by the leaves. Pistillate scales pale or colorless and largely hyaline-scarious except for the firmer midrib, commonly accuminate or shortly awn tipped, shorter than the perigynia and often largely concealed among them. Perigynia pale greenish or stramineous, very slender, mostly 1/8 to inch long and <1/16 inch wide, 5 to 7 times as long as wide, planoconvex, several-nerved dorsally, few-nerved ventrally, with an elongate, narrow, strongly serrulate, bidentate beak. Stigmas 2. Achenes lenticular, 1/16 inch long and <1/16 inch wide. Identification Tips: The bracts at the base of the heads are long and foliaceous (3 to 8 inches), much longer than the heads, giving this sedge a distinctive appearance. Phenology: Flowers June through August. Range: Occurs from British Columbia to Ontario, southward 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
