Abstract

fetched live from OpenAlex

Abstract Digitaria killeenii A. S. Vega et Rúgolo, a new species from Bolivia, is described and illustrated. Additional micromorphological characters in the spikelets are also described. The presence of an apical, abaxial pair of stomata on the upper lemma and the presence of occasional brownish hairs on the lower palea constitute the first report in the genus Digitaria. The taxonomic position of D. killeenii is discussed and its inclusion in section Clavipilae (Stapf) Henrard is proposed. A comparative table and some remarks about the related taxa are included. Communicating Editor: Fred Barrie

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
