Type A: In parentheses, the number of starch grains that are closer in shape and size to sorghum (see also Figures S1, S2, and S3).
Type B: ovalish with a central fissure (17–20 μm).
Type C: strongly facetted starch grains (20 μm).
Other unidentified: in parentheses, starch grains that cannot be identified due to damage.
