About Geranium solanderi Carolin
Geranium solanderi is a perennial spreading herb whose growing tips grow upward. Stems reach up to 50 cm in length and are covered in coarse hairs. It has a swollen, often turnip-shaped taproot. Leaves on flowering stems are opposite and palmatisect, meaning they are cut into lobes extending more than halfway toward the center in a palmate arrangement. These leaves measure 1–3 cm long by 1.5–5 cm wide, have 5–10 lobes, are hairy, and grow from a leaf stalk (petiole) up to 5 cm long. Flowers are most commonly paired, rarely solitary, borne on an inflorescence stalk (peduncle) 1–4 cm long. Each individual flower sits on its own flower stalk (pedicel) 2.5–5 cm long. Sepals are 5–9 mm long. Petals are pink, 5–12 mm long, and often marked with yellowish veins. Anthers are yellow. Fruits measure 12–25 mm long, and the seeds produced are black. The Noongar people of south west Western Australia traditionally used cooked older red tuberous roots of this species to treat diarrhoea.
