Megasporogenesis and Megagametogenesis of Cardamine Parviflora L. (Brassicaceae)
Bibliographic record
Abstract
ABSTRACT Cardamine parviflora, “small-flowered bittercress”, is a member of the Brassicaceae family. It is found throughout the eastern part of the United States and Canada. Flowering occurs from April through July. It has, as with all mustards, four separate sepals and four separate petals, six stamens, and one pistil with two united carpels. Each carpel has many ovules that start develop from the base of the ovary. Flowers were collected near Rocky Ridge County Park, York, PA and immediately fixed in FPA50. At least 24 h later collections were serially dehydrated to 100% ETOH, and placed in Herr clearing fluid. A Nikon SMZ-U dissecting microscope was used for ovule removal and an attached DSFi1 Nikon digital camera was used to capture the images. Ovules, on the Raj slides, were viewed using a Nikon Eclipse 80i microscope with phase contrast to determine developmental stages and the attached Nikon digital cameras DS-Ri1 was used for image capture. Images of all stages of megasporogenesis and megagametogenesis were saved. A few morphological features determined from this study include are, ovules are campyloptropous, bitegmic and show Polygonum Type megagametophytic development. Developmental features reported here are compared with previous studies of Arabidopsis thaliana L. and Draba verna L.

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.
