Abstract

fetched live from OpenAlex

A taxonomic revision of the Schoenus compar - Schoenus pictus and allies group is presented, following a recent taxonomic realignment that transferred 24 southern African species into Schoenus from Tetraria and Epischoenus. In light of recent field collections and a thorough review of herbarium specimens, we revise the delimitations and distributions of three species (Schoenus compar, Schoenus arenicolus and Schoenus pictus) and raise Schoenus pseudoloreus to species level from its previous status as a variety of Tetraria sylvatica. In addition, we describe three new species (Schoenus aureus, Schoenus megacarpus and Schoenus filiculmis) predominantly occurring in the Cape Floristic Region of South Africa. Species in this group have either dilated primary inflorescence bracts or membraneous marginal extensions on the bracts that either partially or entirely cover spikes. Moreover, the sheaths and ligules are most often open and membranaceous. We present an identification key for these seven species and update their nomenclature, as well as provide detailed descriptions and distribution maps.

Full frame distilled prediction

Teacher imitation

Not 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.
