Pomaderris is a genus of about 80 species of flowering plants in the family Rhamnaceae, the species native to Australia and/or New Zealand. Plants in the genus Pomaderris are usually shrubs, sometimes small trees with simple leaves arranged alternately along the branches and bisexual, woolly-hairy flowers arranged in racemes or panicles. The flowers are usually yellow and often lack petals.
Plants in the genus Pomaderris are shrubs, sometimes small trees, the young stems, lower surfaces of the leaves and flower parts are covered with woolly, star-shaped and simple hairs. The leaves are arranged alternately along the branches and are simple, with brown stipules at the base of the petiole but that are usually shed as the leaf matures. The flowers are arranged in small cymes, the groups arranged in racemes or panicles, and are usually yellow. The flowers have five sepals but the petals are usually absent or fall off as the flower opens, and there are five stamens in each flower. The fruit is a capsule that eventually splits into three valves. [2] [3] [4] [5]
The genus Pomaderris was first formally described in 1805 by Jacques Labillardière in his Novae Hollandiae Plantarum Specimen . [6] The genus name means "a covering of leather or skin" referring to the valves of the fruit. [5]
Species of Pomaderris occur in all Australian states and the Australian Capital Territory, but not the Northern Territory and in both the North and South Islands of New Zealand. Sixty-five of the species are native to Australia and the other five are from New Zealand. There is some overlap. A distinctive feature of the leaves, branches, and twigs of this genus, is that they are hairy.
Pomaderris species are used as food plants by the larvae of some Lepidoptera species including Aenetus ligniveren .
A few of species in this genus are known to horticulture; the most commonly cultivated species is P. aspera , the hazel pomaderris.
The following is a list of Pomaderris species accepted by Plants of the World Online as at December 2021, [7] other than P. ferruginea which is accepted by the Australian Plant Census: [8]
Leptospermum is a genus of shrubs and small trees in the myrtle family Myrtaceae commonly known as tea trees, although this name is sometimes also used for some species of Melaleuca. Most species are endemic to Australia, with the greatest diversity in the south of the continent, but some are native to other parts of the world, including New Zealand and Southeast Asia. Leptospermums all have five conspicuous petals and five groups of stamens which alternate with the petals. There is a single style in the centre of the flower and the fruit is a woody capsule.
Grevillea, commonly known as spider flowers, is a genus of about 360 species of evergreen flowering plants in the family Proteaceae. Plants in the genus Grevillea are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds.
Leucopogon is a genus of about 150-160 species of shrubs or small trees in the family Ericaceae, in the section of that family formerly treated as the separate family Epacridaceae. They are native to Australia, New Zealand, New Caledonia, the western Pacific Islands and Malaysia, with the greatest species diversity in southeastern Australia. Plants in this genus have leaves with a few more or less parallel veins, and tube-shaped flowers usually with a white beard inside.
Prostanthera, commonly known as mintbush or mint bush, is a genus of about 100 species of flowering plants in the mint family Lamiaceae, and all are endemic to Australia. Plants are usually shrubs, rarely trees with leaves in opposite pairs. The flowers are arranged in panicles in the leaf axils or on the ends of branchlets. The sepals are joined at the base with two lobes. The petals are usually blue to purple or white, joined in a tube with two "lips", the lower lip with three lobes and the upper lip with two lobes or notched.
Persoonia, commonly known as geebungs or snottygobbles, is a genus of about one hundred species of flowering plants in the family Proteaceae. Plants in the genus Persoonia are shrubs or small trees usually with smooth bark, simple leaves and usually yellow flowers arranged along a raceme, each flower with a leaf or scale leaf at the base. The fruit is a drupe.
Olearia, most commonly known as daisy-bush, is a genus of flowering plants belonging to the family Asteraceae, the largest of the flowering plant families in the world. Olearia are found in Australia, New Guinea and New Zealand. The genus includes herbaceous plants, shrubs and small trees. The latter are unusual among the Asteraceae and are called tree daisies in New Zealand. All bear the familiar daisy-like composite flowerheads in white, pink, mauve or purple.
Baeckea is a genus of flowering plants in the myrtle family, Myrtaceae, all but one endemic to Australia. Plants in the genus Baeckea are shrubs or small trees with leaves arranged in opposite pairs, white to deep pink flowers with five sepals and five petals, and five to fifteen stamens that are shorter than the petals.
Westringia is a genus of Australian shrubs. As with other members of the mint family their upper petal is divided into two lobes. There are four stamens - the upper two are fertile while the lower two are reduced to staminodes. The leaves are in whorls of 3 or 4.
Dillwynia is a genus of about 20 species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in this genus are shrubs with simple leaves and yellow or red and yellow flowers similar to others in the family.
Cassinia is a genus of about fifty-two species of flowering plants in the family Asteraceae that are native to Australia and New Zealand. Plants in the genus Cassinia are shrubs, sometimes small trees with leaves arranged alternately, and heads of white, cream-coloured, yellow or pinkish flowers surrounded by several rows of bracts.
Philotheca is a genus of about fifty species of flowering plants in the family Rutaceae. Plants in this genus are shrubs with simple leaves arranged alternately along the stems, flowers that usually have five sepals, five petals and ten stamens that curve inwards over the ovary. All species are endemic to Australia and there are species in every state, but not the Northern Territory.
Hovea is a genus of about forty species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in this genus are sub-shrubs, shrubs or small trees with simple leaves and purple, blue or mauve flowers with a white centre. The fruit is a pod containing brown to blackish seeds. Species of Hovea occur in all Australian states, the Australian Capital Territory and the Northern Territory.
Gompholobium, commonly known as glory peas or wedge-peas, is a genus of plants in the pea family Fabaceae and is endemic to Australia. Most species have compound leaves composed of three leaflets and all have ten stamens which are free from each other and a distinctive arrangement of their sepals.
Bossiaea is a genus of about 78 species of flowering plants in the pea family Fabaceae and is endemic to Australia. Plants in this genus often have stems and branches modified as cladodes, simple, often much reduced leaves, flowers with the upper two sepal lobes larger than the lower three, usually orange to yellow petals with reddish markings, and the fruit a more or less flattened pod.
Daviesia, commonly known as bitter-peas, is a genus of about 130 species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in the genus Daviesia are shrubs or small trees with leaves modified as phyllodes or reduced to scales. The flowers are arranged singly or in groups, usually in leaf axils, the sepals joined at the base with five teeth, the petals usually yellowish with reddish markings and the fruit a pod.
Spyridium is a genus of plants in the family Rhamnaceae. It includes about 30 species found in southern Australia.
Lepidosperma is a genus of flowering plant of the family Cyperaceae. Most of the species are endemic to Australia, with others native to southern China, southeast Asia, New Guinea, New Caledonia and New Zealand.
