Fig. 1. — Stomatal characteristics of two Begonia species. The upper panel displays representative micrographs from the abaxial side of B. coccinea and B. plebeja. Scale bar=20 μm. Stomatal patterning was determined from epidermal peels of B. coccinea and B. plebeja. Graphs represent (A) stomatal density (light grey) and stomatal size (dark grey), (B) stomatal stomatal index, (C) maximum stomatal opening, and (D) percentage of stomatal closure relative to the maximum for that species. Data are means ±SE of n >60 stomata. The asterisk indicates a statistical difference (P<0.05), as determined by two-tailed t-test.
