Plants in the genus ''Hemiandra'' are shrubs with sessile leaves arranged in opposite pairs, petals with five lobes arranged in two "lips" and the fruit a capsule usually containing four nuts.
==Description== Plants in the genus ''Hemiandra'' are prostrate to medium shrubs with rigid, leathery, sessile leaves arranged in opposite pairs. The flowers have five egg-shaped sepals fused at the base and five petals fused at the base to form a corolla with two "lips". The upper lip short of the corolla is erect with two lobes, the lower lip longer, spreading and three-lobed. The middle lobe itself often has two lobes. The flowers are white, pink or purple, often spotted in the throat. There are four stamens and a single style with two stigmas. The fruit is a capsule usually containing four nuts.<ref name=FloraBase>{{FloraBase | name = ''Hemiandra'' | id = 22012}}</ref><ref name="DEC">{{cite web |title=''Hemigenia'' and ''Hemiandra'' |url=https://www.dpaw.wa.gov.au/images/documents/about/science/pubs/seednotes/sn16_hemigenia.pdf |publisher=Western Australian Government Department of Environment and Conservation |access-date=31 January 2021}}</ref>
