Floral Development and Phylogenetic Position of<i>Schismatoglottis</i>(Araceae)
Bibliographic record
Abstract
In the inflorescence of Schismatoglottis, atypical sterile flowers are present between the male and female zones. Contrary to what occurs in Cercestis and Philodendron, where the atypical flowers are bisexual, in Schismatoglottis the atypical flowers consist of aberrant male or female flowers. These atypical unisexual flowers have different forms depending on their position in the inflorescence. The atypical flowers located near the male zone share characteristics with staminate flowers, and those located near the female zone have features in common with pistillate flowers. The developmental pathway of atypical flowers in Schismatoglottis is already channeled in the direction of female or male flowers before the appearance of aberrant appendages. Interpistillar sterile structures located in the female zone correspond to modified female flowers. The systematic position of Schismatoglottis is not fully resolved on a molecular phylogenetic analysis of 45 genera of Araceae, on the basis of chloroplast trnL intron and trnL‐F intergenic spacer sequences. The floral ontogenetic pattern in Schismatoglottis represents a different pathway in the evolution of unisexual flowers in the subfamily Aroideae.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
