Navigating the floral Milky Way: the taxonomy of the microgeophytic triggerplants (Stylidium petiolare and allies: Stylidiaceae)
Bibliographic record
Abstract
Stylidium petiolare Sond. and allies (Stylidiaceae) are a group of diminutive triggerplants from southern Western Australia that have evolved small corms capable of significant desiccation during summer dormancy. A taxonomic review of these microgeophytes has identified 14 taxa, of which S. cornuatum Wege, S. scintillans Wege and S. xanthellum Wege are newly described and S. asteroideum F.L.Erickson & J.H.Willis and S. rubricalyx F.L.Erickson & J.H.Willis are reinstated. S. emarginatum subsp. exappendiculatum Lowrie & Carlquist and S. emarginatum subsp. decipiens Carlquist are elevated to species level and their respective distributions significantly expanded following the assessment of herbarium specimens and field survey. Revised descriptions are provided for S. emarginatum Sond., S. insensitivum Carlquist, S. obtusatum Sond., S. periscelianthum F.L.Erickson & J.H.Willis, S. petiolare Sond., S. pulchellum Sond. and S. udusicola Lowrie & Kenneally. S. bolgartense F.L.Erickson & J.H.Willis is retained as a synonym of a broadly defined S. obtusatum, and S. petiolare var. paucifoliatum Sond. is newly placed into synonymy under S. xanthellum. Lectotypes are selected for S. asteroideum, S. emarginatum, S. petiolare, S. petiolare var. paucifoliatum, S. pulchellum and S. obtusatum. S. emarginatum var. macranthum E.Pritz. is newly placed into synonymy under S. emarginatum, with a neotype designated. S. scintillans, discovered during surveys of mining leases in the Yalgoo region, is considered Threatened in Western Australia, whereas S. asteroideum, S. cornuatum, S. exappendiculatum (Lowrie & Carlquist) Wege, S. periscelianthum and S. rubricalyx are all listed as being of conservation concern. Further field survey and collections of the microgeophytic triggerplants are required to refine the taxonomy presented herein and to better understand the distribution and conservation status of these taxa.
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.
