Abstract Parsonsia praeruptis is described from the
Surville Cliffs, North Cape. It differs from the widespread New Zealand
species
P. capsularis by its non-twining, non-climbing habit, shorter,
ovate leaves with a subcordate base, smaller inflorescences, and glabrous calyx
lobes.
P. praeruptis is an ultramafic endemic and has a total range of
less than 120 ha. Its conservation status is assessed as "Rare" because of
threats from browsing animals and weeds. A key to New Zealand species of
Parsonsia is provided.
