Some details of the internal architecture of potato and canna starches were obtained from uniformly crushed granules. The growth appears to' be principally by intus susception and proceeds along a hilum canal toward the periphery of the granules. The presence of a cavity and hilum canal in potato starch granules is used to explain some swelling phenomena such as bubble formation and invagination. Some evidence of a membrane encasing potato and canna starches is cited. The internal details of wrinkled-pea starch were also studied; the expected shell-type layering was found with this starch and the growth is apparently by apposition.
