Anatomy of the shrimp plant, Justicia brandegeana (Acanthaceae)
Bibliographic record
Abstract
Justicia brandegeana is a popular ornamental plant in North America commonly known as the shrimp plant. In the wild, it grows as a shrub in semi-arid climates. Little is documented on the anatomy of this plant, therefore the purpose of this study was to determine the anatomy of the shrimp plant at the cellular level through various hand sectioning and staining techniques. It was determined that many anatomical features of this plant were synonymous to those of a typical dicotyledonous plant. However there were unique features of this plant that can be linked to its hot/dry environment such as a layer of suberized parenchyma in the stem surrounding the vascular tissue, a thick band of secondary xylem in the stem and root, phi thickenings in cortical cells just inside the exodermis in mature root, and expansion of the Casparian bands in the endodermis consistent with the secondary growth of the vascular tissue in the root. Further research is necessary on plants that have also adapted to semi-arid environments in order to compare and contrast the adaptations found in the anatomy of J. brandegeana.

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.
