Polianthion is a genus of plants in the Rhamnaceae family, first described by Kevin R. Thiele in 2006. [1] [2] The genus name derives from the Greek polios (grey) and anthion (little flower), and describes the small, densely grey-pubescent flowers. [3]
The Rhamnaceae are a large family of flowering plants, mostly trees, shrubs, and some vines, commonly called the buckthorn family. Rhamnaceae is included in the order Rosales.
Banksia burdettii, commonly known as Burdett's banksia, is a species of shrub or tree of the genus Banksia in the family Proteaceae. It occurs on sandplain country north of Gingin, Western Australia. Growing to 4 m (13 ft) in height, it has long serrated leaves and large, bright flower spikes, initially white before opening to a bright orange, that appear mainly in late summer. Edmund Gilbert Baker described B. burdettii in 1934, naming it after its collector, W. Burdett.
Banksia praemorsa, commonly known as the cut-leaf banksia, is a species of shrub or tree in the plant genus Banksia. It occurs in a few isolated populations on the south coast of Western Australia between Albany and Cape Riche.
Banksia prionophylla is a shrub endemic to Western Australia. Known only from a single population of around 70 plants in a remote part of Western Australia, it is considered rare but not endangered. It was first discovered in 2001, and published under the genus Dryandra in 2005, before being transferred into Banksia in 2007.
Cryptandra is a genus of flowering plants family Rhamnaceae and is endemic to Australia.

Kevin R. Thiele is currently an adjunct associate professor at the University of Western Australia and the director of Taxonomy Australia. He was the curator of the Western Australian Herbarium from 2006 to 2015. His research interests include the systematics of the plant families Proteaceae, Rhamnaceae and Violaceae, and the conservation ecology of grassy woodland ecosystems. He also works in biodiversity informatics, developing and teaching the development of interactive multi-access keys, and has been involved in the design of software for the Global Biodiversity Information Facility.
Spyridium is a genus of about thirty species of flowering plants in the family Rhamnaceae, and is endemic to Australia. Plants in the genus Spyridium are shrubs or subshrubs usually with small leaves, flowers usually in clusters of small composite heads, the individual flowers small and densely woolly-hairy, and the fruit a capsule. Species of Spyridium are found in all Australian states except Queensland.
Spyridium globulosum, commonly known as basket bush, is a species of flowering plant in the family Rhamnaceae and is endemic to coastal areas in the south-west of Western Australia. It is a shrub with relatively large leaves and heads of flowers covered with whitish hairs.
Trymalium is a genus of shrubs or trees in the family Rhamnaceae. The species are endemic to Western Australia but for one, Trymalium wayi, that occurs in South Australia. They are found in forest and semiarid woodland and shrubland of the kwongan in southwest Australia, and the outlying species of South Australia is found on rocky slopes, notably at the Mount Lofty and Flinders Ranges.
Alphitonia petriei, commonly known as the white ash, is a rainforest tree in the family Rhamnaceae from eastern and northern Australia. Other common names include red ash, white-leaf, pink almond and pink ash. It was originally collected from the Johnstone River in October 1917 by H. Ladbrook, but the designated type for this species was collected by Cyril Tenison (C.T.) White in March 1922 from the Barron River near Kuranda. It was described and named in 1925 by K.W. Braid and White who assigned the species epithet petriei in honour of W.R. Petrie, who alerted them to its distinctness.

Spyridium burragorang, is a flowering shrub in the family Rhamnaceae. It has dense clusters of whitish flowers at the end of branches, alternate leaves and is endemic to New South Wales.
Pomaderris rotundifolia is a species of flowering plant in the family Rhamnaceae and is endemic to Western Australia. It is an upright, spreading shrub that typically grows to a height of 0.1–1.5 m, its branchlets covered with star-shaped hairs. The leaves are more or less round leaves and the flowers are white to pink. In most respects it is similar to other species of Pomaderris occurring in Western Australia but has more prominent bracts, shorter pedicels and well developed petals. Flowering occurs from June to October.
Spyridium bifidum, commonly known as forked spyridium, is a species of flowering plant in the family Rhamnaceae and is endemic to South Australia. It is an erect shrub with densely softly-hairy young stems, wedge-shaped to linear leaves sometimes with a two-lobed tip, and densely woolly heads of white-velvety flowers.

It is a shrub that typically grows to a height of 0.1–1.6 m and has white to cream-coloured or yellow flowers from February to October. It grows on coastal dunes and stony hillsides in near-coastal areas in the Esperance Plains, Jarrah Forest and Warren bioregions of southern Western Australia.
