The Restionaceae, also called restiads and restios, are a family of flowering plants native to the Southern Hemisphere; they vary from a few centimeters to 3 meters in height. Following the APG IV (2016): the family now includes the former families Anarthriaceae, Centrolepidaceae and Lyginiaceae, and as such includes 51 genera with 572 known species. Based on evidence from fossil pollens, the Restionaceae likely originated more than 65 million years ago during the Late Cretaceous period, when the southern continents were still part of Gondwana.
Knightia is a small genus of the family Proteaceae endemic to New Zealand, and named in honor of Thomas Andrew Knight. One extant species, K. excelsa (Rewarewa) is found in New Zealand, while a fossil species from upper Miocene deposits in Kaikorai has been described as Knightia oblonga. Two species from New Caledonia, described in the genus Knightia have been placed in the genus Eucarpha by Lawrie Johnson and Barbara Briggs in their influential 1975 monograph "On the Proteaceae: the evolution and classification of a southern family"., although the nomenclatural combinations have never been published as of today.

It is an evergreen shrub to small tree and is endemic to the heaths and button grass sedgelands of western Tasmania. It occurs most often in moist heath and scrub and occasionally in the alpine regions, but generally prefers well-drained but poor soils. It can grow in some rainforests where it forms a small tree but is normally a shrub in all other situations. The heaviest concentrations are along the island's south coast. Its leaves are dark green, hairless and almost succulent. Masses of white flowers are produced in erect spikes from the ends of the branches. Measuring 8 to 12 cm high, they appear in January and February.
