A Morphometric Study of Synechanthus (Palmae)
Bibliographic record
Abstract
Abstract Synechanthus, a genus of two species, is widely distributed from southern Mexico through Central America to the Pacific coast of Colombia and Ecuador. Univariate, bivariate, and multivariate statistical methods, based on data taken from herbarium specimens, were used to examine morphological variation between and within species. The species are clearly distinguished based on qualitative variables, and means of most quantitative variables are significantly different between the two. Synechanthus warscewiczianus is distributed more or less continuously from Nicaragua to Ecuador. No variables are correlated with latitude, but three are correlated with elevation. In central Panama, small-sized plants occur on three isolated peaks. These can be separated from larger-sized plants with discriminant analysis, and two of the three small-sized populations can be separated from each other. The distribution of S. fibrosus, from Mexico to Costa Rica, encompasses three separate populations that can be distinguished from one another by discriminant analysis. No variables are correlated with elevation or latitude. Communicating Editor: Fred R. Barrie

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.
