Melanthiaceae, also called the bunchflower family, is a family of flowering herbaceous perennial plants native to the Northern Hemisphere. Along with many other lilioid monocots, early authors considered members of this family to belong to the family Liliaceae, in part because both their sepals and petals closely resemble each other and are often large and showy like those of lilies, while some more recent taxonomists have placed them in a family Trilliaceae. The most authoritative modern treatment, however, the APG III system of 2009 (unchanged from the 2003 APG II system and the 1998 APG

It is sometimes given the English name paintbrush, not to be confused with Castilleja species which also have this name. It is an evergreen bulbous perennial geophyte, prized horticulturally for its unusual appearance and extreme tolerance of neglect. H. albiflos is the only Haemanthus species found in both winter and summer rainfall regions, and has a mainly coastal distribution from the southern Cape through the Eastern Cape to KwaZulu-Natal, showing a

Polygala serpyllifolia, the heath milkwort, is a European native perennial of heaths and grassy places.

Mertensia is a genus of flowering plants in the borage family Boraginaceae. They are perennial herbaceous plants with blue or sometimes white flowers that open from pink-tinged buds. Such a change in flower color is common in Boraginaceae and is caused by changes in soil pH. Mertensia is one of several plants that are commonly called "bluebell". In spite of their common name, the flowers are usually salverform (trumpet-shaped) rather than campanulate (bell-shaped). Mertensia is native to most of North America and to a large part of Asia from western China to northeastern Russia. Its center of

Hakea ( HAH-kee-ə, HAY-) is a genus of about 150 species of flowering plants in the family Proteaceae, 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

The Asclepiadoideae are a subfamily of flowering plants in the family Apocynaceae. Formerly, these plants together with those now in the Apocynaceae subfamilies Periplocoideae and Secamonoideae were treated as a separate family under the name Asclepiadaceae, e.g. by APG II, and known as the milkweed family. They form a group of perennial herbs, twining shrubs, lianas or rarely trees but notably also contain a significant number of leafless stem succulents. The name comes from the type genus Asclepias (milkweeds). There are 348 genera, with about 2,900 species. They are mainly located in the

Drosera peltata, commonly called the shield sundew or pale sundew, is a climbing or scrambling perennial tuberous species in the carnivorous plant genus Drosera. Among the tuberous sundews, D. peltata has the largest distribution, which includes eastern and western Australia, New Zealand, India, and most of Southeast Asia including the Philippines. The specific epithet is Latin for "shield shaped", a reference to the shape of the cauline leaves. It is either a single extremely variable species, or a complex of several closely related species of uncertain taxonomic boundaries. In Australia at

Ulex minor, the dwarf furze or dwarf gorse is an evergreen dwarf shrub in the family Fabaceae, native to eastern England, France, Spain and Portugal. It is restricted to lowland heathland habitats. It normally grows about 30 centimetres (10 in) tall, although in shaded, ungrazed conditions it may reach 1 metre (40 in). It is a low-growing shrub, forming small bushes or often growing mingled with heather. The leaves are limited to scales or small spines, and the shoots are modified into rather soft, green, densely crowded spines, about 1 cm (0.4 in) long. The flowers are yellow, 1–2 cm

Flacourtia jangomas is a species of flowering plant in the family Salicaceae. This lowland and mountain rain forest tree is sometimes referred to by the English common names Indian coffee plum, Indian plum, or scramberry. It was once placed in the Flacourtiaceae family. It is widely cultivated in Southeast and East Asia, and has escaped cultivation in a number of places. Its wild origin is unknown but is speculated to be tropical Asia, most likely India and Sri Lanka.

Celtis tournefortii, commonly known as the oriental hackberry, is a deciduous tree in the genus Celtis. The species is found in southeastern Europe from Sicily east to the Balkans and Crimea, West Asia, and the Caucasus. It can grow up to 6 metres (20 ft) in height and grows in plains and dry forests.

Epacris is a genus of about forty species of flowering plants in the family Ericaceae. It was formerly treated in a closely related but separate family Epacridaceae, but the various genera within Epacridaceae including Epacris have been revised in their relationships to each other and brought under the common umbrella of the Ericaceae. The genus Epacris is native to eastern and southeastern Australia (southeast Queensland south to Tasmania and west to southeast South Australia), and New Zealand. The species are known as heaths or Australian heaths.

Angophora is a genus of nine species of trees and shrubs in the myrtle family, Myrtaceae.
