Description
Plants in the genus ''Hardenbergia'' are climbing or trailing herbs or subshrubs with leaves arranged alternately along the stems. The leaves are pinnate with one, three of five leaflets with
stipules at the base and
stipellae at the base of the leaflets. The flowers are usually arranged in pairs or small clusters in leaf axils and are medium-sized, violet, white or pinkish, the
standard petal with a yellowish or greenish centre. The
sepal

Baron von Huegel who visited Australia in 1833.
