Abstract

fetched live from OpenAlex

A comprehensive molecular study, using sequence data from nuclear ITS rDNA and plastid rbcL and matK exons, rps16 intron, and the trnL-F intronic and intergenic spacer, was used to assess the taxonomic status of Thecanthes Wikstr., and to evaluate the relationships within Pimelea Banks & Sol. ex Gaertn. and Thecanthes (Thymelaeaceae). Both genera are Australasian and they constitute the subtribe Pimeleinae, which is characterised by a reduction to two stamens. Previous studies indicated a close relationship among Pimelea, Thecanthes and Gnidia L. species from tropical Africa. We conclude that Pimelea and Thecanthes form a strongly supported clade, with Thecanthes possibly included within Pimelea, although we await further data before formally proposing a series of new taxonomic combinations.

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.
