<i>Ceiba pentandra</i> (Malvaceae) and associated species: Spiritual Keystone Species of the Neotropics
Bibliographic record
Abstract
Among the 18 species included in the Ceiba genus in the Malvaceae (Bombacoideae) family, Ceiba pentandra (L.) Gaertn. is not only the tallest and most widespread but also occupies the most prominent place in Neotropical cosmovisions. In this ethnobotanical review, we compare perceptions and uses of Ceiba and related species across Indigenous and Afro-descendant cultures ranging from the Caribbean to the Argentinian Chaco. Ceiba’s widely shared role as axis mundi (particularly in Amazonia), psychopomp, and as a shelter of major forest spirits makes it a perfect example of a Spiritual Keystone Species, a new concept inspired from the concept of Cultural Keystone Species and defined here for the first time.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
