84 * RESEDACEAE 
Annual to perennial herbs, rarely shrubs (not in Tas.). Leaves alternate; stipules small, often reduced to glandular teeth; lamina simple, entire to deeply pinnatifid. Inflorescence a terminal spike or raceme. Flowers bisexual or rarely unisexual, irregular, occurring in axils of bracts; receptacle hypogynous to perigynous. Sepals 4–8, green, valvate in bud. Petals (0, 2)4–8, white to yellow, free, unequal, entire or lobed, the posterior 1–2 largest, the lateral 2 and the anterior 1–2 progressively smaller and less lobed. Stamens 3–50+, inserted on a nectar-secreting disk; filaments free or joined at the base; anthers bilocular. Carpels (2)3–6(7), free (not in Tas.) or united forming a unilocular ovary that is open at the top; ovules numerous, placentation parietal or basal; stigmas as many as carpels and borne on apical lobes of each carpel. Fruit a dry open capsule or berry (not in Tas.). Seeds reniform to suborbicular.
A family of 6 genera and about 80 species native to central and south-western Asia, Africa, southern Europe, Atlantic Islands and south-western North America, widely naturalized elsewhere. 1 genus and 5 species introduced in Australia, 3 species introduced in Tasmania. Resedaceae are placed in the Brassicales near Gyrostemonaceae (Australia; see Ronse de Craene & Haston 2006).

R. odorata +
+ Reseda odorata L. (Sweet Mignonette), a native of north Africa and south-eastern Europe, is cultivated throughout the world. In Tasmania, it was recorded for the first time in 2000 from a roadside at Lughrata, Flinders Island. In South Australia it is recorded as sparingly naturalized. For a full description of this species see Pearce (1982).2 of 3
