Bibliographic record
Abstract
6. Pleurotaenium subcoronulatum var. detum West & G.S. West 1896: 235, pl. 13: figs 2, 3 Type locality: USA. Description: The apices of the semicells are dilated and a clear abrupt constriction is situated at a distance of approximately one seventh of the semicell length from the pole (Fig. 4E). The cell wall is very slightly undulated beyond the basal inflation. The number of tubercles ranges from 26–30. The cells are about 11–19 times longer than wide. Cells are 404–446 µm long, and 29–38 µm wide at the base of the semicell. The apex is 27–28 µm wide, while the width at the constriction is 20–27 µm. Distribution: North America: Canada (Irénée-Marie 1939; Poulin et al. 1995), USA (West & West 1896; Smith 1924; Brown 1930; Prescott et al. 1975; Dillard 1990; Akin & Meyer 1996; Marshall et al. 2005; Laderman & Domozych 2005; Smith 2010). Central America: Cuba (Comas 2009). South America: Argentina (Tell 1985), Brazil (Bicudo & Ungaretti 1986; Souza 2008). Africa: Democratic Republic of the Congo (Van Oye 1953; Golama Swana Kaketa 1996), Guinea (Bourrelly 1975), Mozambique (Rino 1972); Sierra Leone (Grönblad et al. 1968); Uganda (Grönblad et al. 1964); Zimbabwe (Rich 1935). Lakes on borders of African countries: Tanganyika, Victoria (Cocquyt et al. 1993). Asia: Japan (Hirose et al. 1977), Russian Federation (Medvedeva 2023). Australia and New Zealand: Australia (Day et al. 1995).

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.
