A new species of pink-flowered Leptocereus (Cactaceae) from Cuba
Bibliographic record
Abstract
A new species of Leptocereus (Cactaceae) from Cuba is described and illustrated. We compare Leptocereus gonzaleztorresii sp. nov. based on morphological and anatomical data with other cacti of the Cuban subclade of pink-flowered Leptocereus (L. leonii, L. scopulophilus, L. wrightii), to which it belongs. Twenty-one vegetative and reproductive characters were analyzed through canonical discriminant and classificatory analyses to evaluate the separation between species. Leptocereus gonzaleztorresii is characterized by flowers with external stamens with aborted anthers, and brown fruits. Classificatory analyses correctly classified 100 % of the individuals of L. gonzaleztorresii. We provide an identification key to the Cuban subclade of the pink-flowered Leptocereus.

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.
