Figure 2From: Developmental variation and the evolution of distyly in Hedyotis caerulea (Rubiaceae) Stigma development in pin and thrum floral morphs of H. caerulea. Data of bud lengths (mm) versus height of the stigmas (mm) were plotted for each bud collected across five populations (A-E), and F provides results for all populations combined, and lines of best fit are simple linear regression of bud length predicting stigma height.Back to article page
