The taxonomic status of Mimulus sookensis (Phrymaceae) and comments on related aspects of biology in species of Erythranthe
Bibliographic record
Abstract
Mimulus sookensis Benedict et al. (2012) is a tetraploid from the Vancouver Isl and area, western Oregon, and northwestern California hypothesized in molecular studies to be of hybrid origin between diploid Erythranthe [Mimulus] nasuta and diploid Erythranthe [Mimulus] guttata . The putative non-nasutus parent in these studies apparently is more accurately identified as Erythranthe [Mimulus] microphylla. Molecular evidence indicates that M. sookensis had two independent origins (disjunct northern and southern population systems) or perhaps a s many, at least, as 11 independent origins. In the study that identified two origins, molec ular evidence clusters the non-nasutus parent of the northern tetraploids among populations sampled from centra l California counties, but the nonnasutus parent of the southern tetraploids was not identified . Mimulus sookensis and typical E. nasuta often can be distinguished by slight differences in sizes when growing side-by-side, but size ranges of plants, flowers, and fruits are completely overl apping when the populational perspective is broadened, and the tetraploid is otherwise similar to the di ploid in every morphological respect. It is impossible to distinguish them in the herbarium. In contras t, experimental hybrids and naturally occurring nasuta-microphylla hybrids apparently of contemporary origin are intermediat e in morphology. Other examples of hybridization and introgression between Erythranthe nasuta and E. microphylla /E. guttata are reviewed. The origin and status of the hexaploid hybrid Mimulus peregrinus are reviewed and two associated nomenclatural combinations are made: Erythranthe peregrina ( Vallejo-Marin ) Nesom, comb. nov. , and Erythranthe ◊ robertsii (Silverside) Nesom, comb. nov.

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.
