It is an open, straggly shrub with densely hairy branches, three-part leaves and groups of up to fifteen flowers with four creamy-white petals and four stamens. DescriptionZieria vagans is an open, straggly shrub which grows to a height of {{convert|2|m|ft|sigfig=1|abbr=on}} and has thin branches covered with soft hairs when young. The leaves are composed of three narrow elliptic leaflets, the central leaflet {{convert|32-45|mm|in|sigfig=1|abbr=on}} long and {{convert|3-6|mm|in|sigfig=1|abbr=on}} wide. The leaves have a petiole {{convert|5-13|mm|in|sigfig=1|abbr=on}} long. The lower surface of the leaflets is more or less glabrous and the upper surface is rough and has a dense covering of hairs. The flowers are arranged in groups of three to fifteen in leaf axils, the groups shorter than the leaves. The groups are on a hairy stalk {{convert|5-13|mm|in|sigfig=1|abbr=on}} long. The flowers are surrounded by scale-like bracts {{convert|1-6|mm|in|sigfig=1|abbr=on}} long which remain during flowering. The sepals are triangular, about {{convert|1|mm|in|sigfig=1|abbr=on}} long and wide and the four petals are creamy white, elliptic in shape, about {{convert|2|mm|in|sigfig=1|abbr=on}} long, {{convert|1-1.5|mm|in|sigfig=1|abbr=on}} wide and hairy on both surfaces. There are four stamens. Flowering occurs between August and February and is followed by fruits which are more or less glabrous capsules about {{convert|4|mm|in|sigfig=1|abbr=on}} long and {{convert|2|mm|in|sigfig=1|abbr=on}} wide.[1]Taxonomy and namingZieria vagans was first formally described in 2007 by Marco Duretto and Paul Forster from a specimen collected in a state forest near Binjour and the description was published in Austrobaileya.[2] The specific epithet (vagans) is a Latin word meaning "wandering" or "unsettled",[3] referring to some populations of this species growing between woodland and vine thicket.[1]Distribution and habitatThis zieria is only known from the Gurgeena Plateau near Binjour in the Brigalow Belt bioregions where it grows in or near vine thicket dominated by Backhousia kingii.[1] References1. ^1 2 {{cite journal|last1=Duretto|first1=Marco F.|last2=Forster|first2=Paul I.|title=A taxonomic revision of the genus Zieria Sm.
