Key to Tasmanian Dicots
Patersonia (Iridaceae) 4b:403
Tasmania has two native species of Patersonia. Both species have long, flat, thick leaves that form clumps in heaths and sedgeland (P. fragilis) or swampy places (P. occidentalis). The flowers are pale to moderately bright blue to violet, with three obvious petal-like sepals, and three much smaller petals.
