Abstract

fetched live from OpenAlex

rhizomes, plant totally submerged except for a flowering spike; fruiting in late June-late August. SIMILAR SPECIES: Potamogeton hillii is a member of a distinctive group of pondweeds with linear, wholly submerged leaves. Many members of this group are similar. Leaves are variable and subject to environmental control, and stipules, inflorescences, and fruits are useful for good identification. This species is distinguished by the largest fruits in the group (3-4 mm. long), a capitate inflorescence, and short peduncles. TOTAL RANGE: Irregularly from MA and VT to PA and w. to Ontario, OH, and MI. STATE RANGE (as of 2008): There are post-1980 records from Ashtabula and Geauga counties. HABITAT: Cold, clear, slow-moving water in streams, ponds, and beaver ponds with a muddy substrate. Hellquist (1977, 1984) has observed it mostly in highly alkaline waters. HAZARDS: Some pondweeds are known to be very intolerant of degradation of water

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.
