Cotyledon areoles are reported for the first time in Phaseoleae subtribe Kennediinae. All three genera, Kennedia, Hardenbergia and Vandasina, have cotyledon areoles in mature dormant seeds. The remarkably uniform seeds also consistently have an adaxial palisade layer in cotyledons and a greatly expanded middle endosperm layer, which appears to consist primarily of normal legume cell-wall galactomannan.
