<i>Calathea matudae</i>and<i>C. sousandradeana</i>, New Species of Marantaceae from Mexico and Northern Central America
Bibliographic record
Abstract
Two species of Marantaceae, Calathea matudae H. Kenn. & Ganders from Chiapas, Mexico, to Honduras, and C. sousandradeana H. Kenn. & Ganders from Veracruz and Oaxaca, Mexico, are described as new for inclusion in Flora Mesoamericana. Calathea matudae differs from C. atropurpurea Matuda in lacking reduced basal inflorescences, the bract acumen that is shorter and acute at the tip, the bracts that consistently dry brown, and the cross veins between the lateral veins of the leaves that are farther apart (15 to 20 per 5 mm vs. 23 to 30 per 5 mm in C. atropurpurea). Calathea sousandradeana differs from C. matudae and C. atropurpurea by the smaller, glabrous bracts with obtuse to rounded margins in the upper ones. A key is provided to the Mexican species in Calathea sect. Breviscapus Benth.
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.
