Indigofera

Queensland

This key requires flowers to be present, especially for length. However, even if the petals have already fallen, the staminal tube often persists and is usually only slightly shorter than the keel. Pods are required for some couplets: these species almost always have pods present. Stipules may be deciduous early, but can usually be found at the base of immature leaves. A hand lens may be needed to observe hair characters.
