Abstract
Macarthuriaceae Christenh., fam. nov. Type of the family:— Macarthuria Hügel ex Endlicher (1837: 11). These are rigid or wiry, rush-like, perennial herbs or subshrubs with green stems. Leaves are alternate, with or without a petiole, lacking stipules. The blades are simple, linear or progressively reduced upwards to scales along the stem. Leaf blades have entire margins and obscure venation. Inflorescences are many-flowered, axillary or terminal compound cymes, or flowers solitary in the leaf axils. Flowers are actinomorphic and bisexual. The five or ten sepals are in two whorls and fused at the base. Petals are five and free, or absent. The eight stamens have filiform filaments that are fused to each other at the base. Anthers are basifixed and opening by lengthwise slits. The superior ovary is composed of three carpels that are fused into a single (or rarely three) locule(s). The three stylodes are fused into a single style at the base, each with an unlobed stigma. Fruits are loculicidal capsules with up to ten seeds. The family differs from Molluginaceae and Microteaceae in having five petals (usually absent in Molluginaceae and Microteaceae), the basifixed anthers (dorsifixed in Molluginaceae and Microteaceae) and the three carpels forming a single locule (one to five carpels each forming a locule in Molluginaceae). They are shrubs that predominately photosynthesize with their rush-like stems; the leaves are often reduced and insignificant.
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.

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.
