Characteristics of Amelanchier lucida (Rosaceae) based on an examination of the holotype and plants from the type locality
Bibliographic record
Abstract
Although reported to be essentially glabrous, a hairy ovary summit is characteristic of the fruit of Amelanchier lucida, and this helps to explain some of the variation in its taxonomic treatment by recent authors. In many instances plants would have been identified as A. stolonifera. Flowering material is here described for the first time. The erect racemes have lower pedicels 8–22 mm long, and petals are 6–7.5 mm long and 2.5–3.3 mm wide. At flowering, the leaves are tomentose but towards the end of flowering the thick tomentum is lost from the outer surfaces of the sepals and the larger leaves. Stoloniferous habit, glossy leaves, ascending sepals, and pubescent ovary summit are a distinctive combination of features of A. lucida. A key to the stoloniferous species of Amelanchier in Nova Scotia is included.
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.
