Boronia is a genus of about 160 species of flowering plants in the citrus family Rutaceae. Most are endemic to Australia with a few species in New Caledonia, which were previously placed in the genus Boronella. They occur in all Australian states but the genus is under review and a number of species are yet to be described or have the description published. Boronias are similar to familiar plants in the genera Zieria, Eriostemon and Correa but can be distinguished from them by the number of petals or stamens. Some species have a distinctive fragrance and are popular garden plants.
Darwinia, sometimes commonly known as mountain bells or simply bells, is a genus of about 70 species of evergreen shrubs in the family Myrtaceae, endemic to southeastern and southwestern Australia. The majority are native to southern Western Australia, but a few species occur in South Australia, New South Wales and Victoria. The genus was named in honour of Erasmus Darwin, grandfather of Charles Darwin by Edward Rudge in 1816. Most darwinias grow to a height of between 0.2 and 3 m, and many are prostrate shrubs. Most have small, simple leaves and the flowers are often grouped together, each flower with five red, white or greenish petals and ten stamens. In many species, the flowers are surrounded by large, colourful bracts, giving rise to their common names.
Commelinaceae is a family of flowering plants. In less formal contexts, the group is referred to as the dayflower family or spiderwort family. It is one of five families in the order Commelinales and by far the largest of these with about 731 known species in 41 genera. Well known genera include Commelina (dayflowers) and Tradescantia (spiderworts). The family is diverse in both the Old World tropics and the New World tropics, with some genera present in both. The variation in morphology, especially that of the flower and inflorescence, is considered to be exceptionally high amongst the angiosperms.
Flindersia is a genus of 17 species of small to large trees in the family Rutaceae. They have simple or pinnate leaves, flowers arranged in panicles at or near the ends of branchlets and fruit that is a woody capsule containing winged seeds. They grow naturally in Australia, the Moluccas, New Guinea and New Caledonia.
Homoranthus is a genus of about thirty species of plants in the myrtle family Myrtaceae and all are endemic to Australia. Plants in this genus share similarities with those in both Darwinia and Verticordia. They are shrubs with their leaves arranged in opposite pairs and with flowers appearing either singly or in small groups, usually in upper leaf axils. They are found in Queensland, New South Wales and South Australia. The genus was first described in 1836. None of the species is common nor are they well-known in horticulture.
Acradenia is a genus of two species of tree or shrub in the family Rutaceae and is endemic to Australia. These plants have leaves that are trifoliate, arranged in opposite pairs and flowers that have five sepals, five petals and usually ten stamens of unequal lengths.
Disphyma is a genus of flowering plants in the family Aizoaceae that are native to New Zealand, Australia and southern Africa. Plants in this genus are prostrate, annual or short-lived perennial shrubs with succulent leaves and daisy-like flowers arranged singly on the ends of shoots with petal-like staminodes, many stamens and usually five styles.
Disphyma crassifolium, commonly known as round-leaved pigface or salty fingers is a species of flowering plant in the family Aizoaceae native to Australia and the Cape Provinces of South Africa. It is a prostrate, succulent annual shrub or short-lived perennial plant with stems up to 2 m long, leaves that are three-sided in cross-section with a rounded lower angle, and purple daisy-like flowers with staminodes up to 30 mm (1.2 in) long.
Carpobrotus glaucescens, commonly known as pigface or iceplant, is a species of flowering plant in the family Aizoaceae and is endemic to eastern Australia. It is a succulent, prostrate plant with stems up to 2 m long, glaucous leaves, daisy-like flowers with 100 to 150 light purple to deep pinkish-purple, petal-like staminodes and red to purple fruit. The fruits ripen mainly in Summer and Autumn. It usually only grows very close to the sea.
Triplarina is a genus of seven species of flowering plants in the family Myrtaceae. They are Baeckea-like shrubs with small leaves arranged in opposite pairs and flowers with five sepals, five more or less round petals, and fourteen to eighteen stamens that are shorter than the petals. Species of Triplarina occur in New South Wales and Queensland usually growing in woodland or forest.
Senna septemtrionalis, commonly known as arsenic bush, is a species of flowering plant in the family Fabaceae and is native to Central America, the southern United States and Mexico, but is naturalised in many other countries. It is an erect shrub with pinnate leaves, with four or five pairs of egg-shaped leaflets, and yellow flowers arranged in groups of five to eight, usually with seven fertile stamens and four staminodes in each flower.
Roscoea cautleyoides is a perennial herbaceous plant occurring in the Sichuan and Yunnan provinces of China. The scientific name is also spelt Roscoea cautleoides. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but R. cautleyoides, like other species of Roscoea, grows in much colder mountainous regions. It is sometimes grown as an ornamental plant in gardens.
Roscoea praecox is a perennial herbaceous plant occurring in the Yunnan province of China. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but R. praecox, like other species of Roscoea, grows in much colder mountainous regions. It is sometimes grown as an ornamental plant in gardens.
Gunniopsis papillata, commonly known as the twin-leaved pigface, is a species of succulent plant in the iceplant family, Aizoaceae and is endemic to inland areas of Australia. It is an annual herb with pimply, spatula-shaped to egg-shaped leaves and flowers with white or yellow petals.
Bouchardatia is a genus of two species of tree in the family Rutaceae, one species endemic to eastern Australia, the other to New Guinea. They have compound leaves with three or five leaflets, and are arranged in opposite pairs. The flowers are bisexual, arranged in panicles, each flower with four sepals, four petals and eight stamens, the petals and stamens all free from each other. The fruit has up to four ridged follicles fused at the base, each containing a single seed.
Disphyma papillatum, commonly known as Chatham Island ice plant, is a species of flowering plant in the family Aizoaceae and is endemic to the Chatham Islands of New Zealand.
