A taxonomic revision of Schoenus compar - Schoenus pictus and allies (Cyperaceae, tribe Schoeneae) with three new species described from South Africa
Bibliographic record
Abstract
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.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
