Westringia parvifolia Westringia parvifolia, Family Lamiaceae, is a spreading shrub growing to 1 m high. Young shoots and flowers are covered with small, white hairs pressed closely to the surface and the branchlets are often hexagonal. Leaves are 1.5–3 mm long, oval-shaped, margins slightly recurved, and arranged along the stem with three leaves forming a ring (whorl) at each node. Flowers are pale purple to white with reddish spots and occur in the upper leaf axils, forming a terminal leafy head of 3–7 flowers (White & Francis, 1921; Boivin, 1949). It is known from a small area near Yelarbon and Inglewood in south-east Queensland. The distribution range is approximately 80 km and there is no available information on population size. Westringia parvifolia flowers between November and February. This species grows with Eucalyptus bakeri and E. viridis and between clumps of Spinifex (Triodia sp.) on sandy and stony soils (BRI collection details, n.d.; White & Francis, 1921).
The main potential threats to Westringia parvifolia include broad-scale vegetation clearing; increasing fragmentation and loss of remnants; hydrological change; and pollution (ANRA, 2007).
