Zieria exsul
Zieria exsul is a plant in the citrus family Rutaceae and is endemic to a small area of southeast Queensland. It is an open, straggly shrub with hairy branches, three-part leaves and white flowers in groups of up to twelve, the groups longer than the leaves and each flower with four petals and four stamens. Description. "Zieria exsul" is an open, weak, straggly shrub which grows to a height of and has relatively smooth but hairy branches. The three-part leaves have a petiole long and a central leaflet which is egg-shaped, long, wide with the  other two leaflets slightly smaller. The upper surface of the leaf is slightly hairy but the lower surface is densely hairy with woolly, star-shaped hairs. The flowers are white and are arranged singly or in groups of up to twelve in leaf axils on a mostly glabrous stalk long, the groups longer than the leaves. The sepals are more or less triangular, about long and wide and the four petals are elliptic in shape, about long and wide. The four stamens are less than long. Flowering occurs mostly occurs between August and September and is followed by fruit which  is a glabrous capsule, about long and wide. This species is similar to "Zieria compacta" except that it is a more straggly shrub and has glabrous flower stalks. Taxonomy and naming. "Zieria exsul" was first formally described in 2007 by Marco Duretto and Paul Forster from a specimen collected in Caloundra and the description was published in "Austrobaileya". The specific epithet ("exsul") is a Latin word meaning "a banished person" referring to this species having been displaced from most of its probable former range. Distribution and habitat. This zieria grows in woodland and wallum heathland near Buderim and Caloundra in  the South East Queensland biogeographic region. Conservation. "Zieria exsul" is listed as "endangered" under the Queensland Nature Conservation Act 1992.
