FIGURE 1. Variation of the four characters used to test the delimitation of Sorghastrum canescens based on measures taken from herbarium samples. Differences in the median values have statistical significance for every character according to the Kruskal-Wallis test (p = 0.01 for spikelet length; p = 0.02 for spikelet width; p <0.01 for awn length; p <0.01 for awn/spikelet length proportion).
