Abstract
Abstract— During bryophyte surveys in the Antón River watershed, Coclé Province, Panama, we discovered a minute rheophytic liverwort representing an undescribed species of Cephaloziellaceae. Phylogenetic analyses based on nuclear ITS1‐2 and plastid rbcL DNA markers placed the new species within Cephaloziella , where it resolved in a clade with C. microphylla , C. kiaeri , and C. recurvifolia in the ITS tree, and with C. microphylla alone in the rbcL tree. We describe the species as Cephaloziella minutiloba . The new species is morphologically distinct by its minute size, flagelliform shoots, scattered violet rhizoids, succubous and highly unequally conduplicate leaves with a prominent ventral lobe and a strongly reduced dorsal lobe bent over the ventral lobe, and crenate-dentate leaf margins. The gynoecia on short ventral branches are made up of 2‐3 series of highly connate, crenate bracts and a 5-plicate perianth with a fringed mouth. This new species expands our understanding of morphological diversity and rheophytic adaptation within Cephaloziella . The morphological affinities of the species are discussed, and the importance of integrative taxonomic approaches in liverwort systematics is emphasized.

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 it
