Gaylussacia Kunth 2024, Nov. Gen.
Bibliographic record
Abstract
2. Gaylussacia Kunth, Nov. Gen. Sp. Pl. 3: 275. 1818. Subshrubs to shrubs, occasionally small trees; branches glabrous or with non-glandular or glandular trichomes, generally with frequent glands on the leaves, especially on the abaxial surface. Leaves more frequently alternate, commonly imbricate; petiole more frequently robust; blades chartaceous to coriaceous, flat or conduplicate, margin flat or slightly to strongly revolute, often with apical glands. Inflorescence in panicle or raceme, axillary or subterminal, bracteate at the base of the inflorescence; bract 1, inconspicuous, bracteoles 2. Bisexual flowers, pentamerous, actinomorphic, diplostemonous, pendulous; calyx conical at the base, not fleshy, short lobes, not accrescent to the fruit; corolla gamopetalous, urceolate, tubular, cylindrical or campanulate, white, pink, or red, lobes straight or recurved; stamens 10, equal among themselves, erect, filaments flattened, anthers bifid, dorsifixed in the lower half, with poricidal dehiscence, truncated thecae, devoid of appendage; ovary inferior, pseudo-10-locular, uniovulate locules, filiform style, and truncated stigma. Fruit type drupoid (nuculanium), with 10 pyrenes; fusiform seeds. Gaylussacia comprises 54 species (Romão et al. 2017) distributed throughout the Americas in three main zones: 1. Eastern North America, from the southern United States to southern Canada; 2. Northern South America, especially in Colombia and Venezuela; and 3. Eastern Brazil, mainly from the states of Bahia to Paraná (Romão 2011). In Brazil, 43 species are identified, of which 42 are exclusive to the country. Recognition of the genus is relatively straightforward, requiring the combination of shrubby habitat and small, showy, campanulate or variations of this flower shape, along with the presence of an inferior ovary with uniovulate locules, and 10 stamens of equal length with straight filaments.
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.
