The Taxonomic Status of Medicago Sinskiae: Insights from Morphological and Molecular Data
Bibliographic record
Abstract
Abstract Medicago sinskiae is a poorly understood but fast-expanding species in western and southwestern Iran. The present study was performed to investigate its relationships with other taxa in the M. rigidula complex including M. constricta, and M. rigidula s.l. (including M. rigiduloides). The Principal Component Analysis (PCA) and cluster analysis were conducted on 29 morphological characters. The group was also examined based on the Internal Transcribed Spacer (ITS) region of the nuclear ribosomal DNA. The morphological and genetic analyses indicated M. sinskiae (including both spiny and spineless variants) was a separate species, most closely related to M. rigidula and M. rigiduloides. The results also showed that the pod of this species had thornless and thorny varieties. Due to the distribution pattern and its presence in the collected samples, M. sinskiae is considered as a species with rapid expansion in the west and southwest of Iran.

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.
