Enantiostyly in <i>Wachendorfia</i> (Haemodoraceae): the influence of reproductive systems on the maintenance of the polymorphism
Bibliographic record
Abstract
Enantiostyly is a form of directional asymmetry in plants in which the style is deflected away from the main axis of the flower, either to the left or right side. In Wachendorfia (Haemodoraceae), a small genus of insect-pollinated geophytes restricted to the Cape Province of South Africa, populations are usually polymorphic for asymmetry. Here we investigate dimorphic enantiostyly in the four species of Wachendorfia to determine whether variation in their reproductive systems influences the maintenance of this genetic polymorphism. Experimental field pollinations of W. paniculata and W. thyrsiflora indicated higher fertility for cross- than for self-pollinations, whereas in W. brachyandra, these types of pollination produced similar levels of fertility. Outcrossing rates were highest in W. paniculata (t = 0.78-0.98), with W. brachyandra (t = 0.39-0.79) and W. thyrsiflora (t = 0.76) exhibiting mixed mating systems. Outcrossing rates in two populations of W. parviflora varied from mixed mating (t = 0.61) to predominant selfing (t = 0.07). Population style-morph ratios ranged from 1 : 1 in outcrossing W. paniculata to monomorphism in selfing W. parviflora and clonal W. thyrsiflora. In W. brachyandra, a species with delayed selfing, morph ratios were usually biased. The maintenance of enantiostyly in Wachendorfia appears to be strongly influenced by levels of disassortative mating and the balance between sexual and clonal recruitment.

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.
