Abstract

fetched live from OpenAlex

Arundinella mainlingensis (Poaceae), a new species from Xizang, China is described and illustrated. This new species forms a sister group relationship with A. yunnanensis on the molecular phylogenetic tree, sharing common morphological characteristics such as ligule extremely short, glumes glabrous and 4−5 mm long and lemma with an apical awn. Arundinella mainlingensis differs from A. yunnanensis in having stems with 3 or 4 nodes, clustered basal leaves, densely covered with tubercle-based hairs on the margins and the adaxial surface, less cauline leaves and lower florets that are male or neuter with short anthers about 1.2 mm long. Arundinella mainlingensis is primarily found in south-eastern Xizang, including Nyingchi, Mainling and Bomê, whereas A. yunnanensis is only observed in Gongshan, Yunnan. These differences further reinforce the classification of the two as distinct species.

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.
