Abstract

fetched live from OpenAlex

Parasitic plant genus Cuscuta is important both economically and ecologically.This study is the result of more than fifteen years of herbarium and field studies in preparation for the floristic account of the genus in Nueva Flora de Chile.Eleven species that belong to three sections of subgenus Grammica were confirmed from Chile.Two historically reported species, C. epithymum and C. grandiflora, were not corroborated by the existing evidence.An identification key, typification, detailed descriptions and illustrations were provided to facilitate the identification of species, and their taxonomy was discussed, outlining remaining problems.Geographical distribution, ecology and host range of species were detailed.Results strongly suggested that several species are likely rare (e.g., C. andina, C. rustica, C. pauciflora) or even extinct (C.werdermannii), emphasizing the need for concerted efforts to locate these species in the wild and establish their conservation status.

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.

Not 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.
