  • The average number of organs per whorl is given. Ler, Landsberg erecta; PSt, petal/stamen; rSt, rudimentary stamen; F, filament; StC, stamen/carpel.

  • a The first 25 flowers were examined on each of five plants.

  • b The first 25 flowers were examined on each of six plants.

  • c The number of first-whorl organs with petal tissue along their margins (see Figure 1F) increased in more apical positions.

  • d 5% of the total first-whorl organs had petal tissue along their margins.

  • e Number of flowers with defect/total number of flowers.
