Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Decumbent to ascending perennial; stems to 50 cm long, with sparse to dense, short, retrorsely appressed hairs and occasionally c. spreading hairs; taproot cylindric to napiform. Leaves orbicular to reniform, 1–4.5 cm long, deeply palmatisect into 3–7, very narrow-linear, deeply trisected (often further divided) primary lobes; ultimate lobes obtuse to acute; upper surface with sparse tiny, curved to appressed hairs; stipules narrow-ovate to lanceolate, acuminate, margins sometimes membranous. Flowers solitary or paired; peduncles 0.8–2.5(–4.5) cm long; pedicels 0.8–2.4 cm long. Sepals ovate to narrow-elliptic, 4.5–7 mm long, acute, pubescent with minute glandular and eglandular hairs, and some longer hairs, mucro 0.5–1 mm long, margin c. translucent; petals obovate, 6–9 mm long, truncate to retuse, bright pink to magenta; anthers yellow. Fruits 11–15 mm long; mericarps with short recurved hairs becoming longer toward awn and dorsal rib, and scattered long hairs, suture margins long-ciliate; seed slightly rugose with small isodiametric alveolae.

A widespread species, occurring predominantly in lowland grasslands and grassy woodlands. Tolerates seasonal drought, but intolerant of prolonged inundation.

Most Victorian material differs from typical Geranium retrorsum from New Zealand as circumscribed by Gardner (1984). Further assessment of this species may result in Victorian (?and Australian) material being reclassified at an infraspecific level.
