Abstract
It has been shown by statistical methods that in Angiosperms significant correlation exists between micropyle formation by both the integuments and six other floral and vegetative characters which are admittedly primitive. A subjective assessment of the primitiveness of the feature in question (i.e., micropyle formation by both the integuments) supports the statistical findings.
