LEGUMINOUS STARCHES
Such as those of beans and peas ([Figs. 15, 16, 17, and 18]), produce but a slight effect under polarized light; the rings are scarcely visible, and the hilum is stellate or much cracked along a median line. This characteristic is more marked in the bean than in the pea. In the latter it resembles fresh dough kneaded again into the center as in making rolls, and in the former the shape assumed by the same after baking. In both it varies in size from .025 to .10 millimeter in length.
