Abstract

fetched live from OpenAlex

General Description: The leaves are strongly papillose on upper surface, involute (edges rolled back), and glaucous (waxy); the widest leaf blades are 1/16 to 1/8 inch wide; the culms are round or very obtusely trigonous (3-angled), and smooth below the inflorescence; long, creeping rhizomes are present. Identification Tips: Carex rostrata and C. utriculata differ conspicuously in their leaves and flowers spikes. C. rostrata leaves are narrow, inrolled, strongly glaucous, and have the stomata on the upper blade surface. Leaf blades of C. utriculata are broader, bright green, and have stomata on the lower surface. The fruiting spikes of C. rostrata are more slender than those of C. utriculata. C. rostrata is currently restricted to the NE part of WA, while C. utriculata has a much broader distribution. Phenology: Flowers and fruits in July and August. Range: Alaska, most of Canada, and northern portions of the United States. In WA, it is currently restricted to the northeast, in the Okanogan Highlands physiographic province. Habitat: Quaking or floating peat in association with slender sedge (C. lasiocarpa) along lake shoreline. Other associated species include mud sedge (Carex limosa), bogbean (Menyanthes trifoliata), pink elephants (Pedicularis groenlandica), great sundew (Drosera anglica), many-spiked cottongrass (Eriophorum polystachion), yellow pond lily (Nuphar polysepalum) and water horsetail (Equisetum fluviatile). Elevation 4500-5000 feet. C. utriculata grows in shallow water on firm substrate with water sedge (C. aquatilis). Ecology: The species is presumably dependent upon physiographic and hydrologic conditions suitable for maintenance of bog systems. Specific information on the species ’ ecology is not available.

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.
