Grevillea is a diverse genus of about 360 species of evergreen flowering plants in the family Proteaceae, native to rainforest and more open habitats in Australia, New Guinea, New Caledonia, Sulawesi and other Indonesian islands east of the Wallace Line. It was named in honour of Charles Francis Greville, an 18th century patron of botany and co-founder of the Royal Horticultural Society. The species range from prostrate shrubs less than 50 cm (20 in) tall to trees 35 m (115 ft) tall. Common names include grevillea, spider flower, silky oak and toothbrush plant. Closely related to the genus Hakea, the genus gives its name to the subfamily Grevilleoideae.
Hakea is a genus of about 150 species of plants in the Family Proteaceae and are endemic to Australia. They are shrubs or small trees with leaves that are sometimes flat, otherwise circular in cross section in which case they are sometimes divided. The flowers are usually arranged in groups in leaf axils and resemble those of other genera, especially Grevillea. Hakeas have woody fruit which distinguishes them from grevilleas which have non-woody fruit which release the seeds as they mature. Hakeas are found in every state of Australia with the highest species diversity being found in the south west of Western Australia.
Exocarpos is a genus of flowering shrubs and small trees in the sandalwood family, Santalaceae. They are found throughout Southeast Asia, Australia and the Pacific Islands.
Lechenaultia is a genus of plants in the family Goodeniaceae. Some species of this genus are used as ornamental plants, in particular L. biloba, L. formosa and L. macrantha.Lechenaultia species are diverse in form: they may be woody or herbaceous, upright or prostrate with leaves flat, needle-like or virtually absent in mature plants. The genus differs from other Goodeniaceae in the structure of the stigma and the fertilization mechanism. They are found in Australia and New Guinea.

Agastachys odorata, commonly known as the white waratah, is the sole member of the genus Agastachys in the protea family. 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.
Monotoca scoparia, commonly known as prickly broom heath, is a widespread native species across south-eastern Australia. Monotoca scoparia was formerly in the family Epacridaceae but now belongs to the family Ericaceae. Monotoca is an endemic Australian genus with 17 described species occurring in all states.
Monotoca oreophila, the mountain broom heath, is a plant in the family Ericaceae. It is endemic to Victoria, Australia. Plants grow to between 0.2 and 2.5 metres high. The elliptic or lanceolate leaves are 3.8 to 11 mm long and 1.4 to 2.8 mm wide. They are stiff, convex and pointed at the apex.
