Bedfordia is a genus of flowering plants belonging to the family Asteraceae. The genus includes 3 species, all endemic to Australia.

Contents

Description

Bedfordia are shrubs or small trees.

Stems and leaves
The young branches and lower surface of leaves and the whorl that surrounds the flower heads are densely covered with short matted and stellate hairs. [2]
Leaves grow first on one side and then on the other in two ranks along the branches; not paired. Leaf edges are entire or with irregular rounded scallops, and have leaf stalks. [2]
Flowers
Heads in dense axillary branched cluster which is shorter than the leaves. Flower heads have a flat circular shape; and are surrounded by a hairy bract which is at base. Tubular, bisexual florets, scarcely longer than the bract. [2]
Fruits and reproduction
Cylindrical, grooved and not hairy achenes. Pappus bristles are finely toothed and twice as long as achenes. [2] B. salicina intergrades with B. arborescens (a tree) and B. linearis (a shrub).

Taxonomy

The genus was first formally described by Swiss botanist Augustin Pyramus de Candolle in the second volume of Archives de Botanique in 1833. [3] The genus name honours John Russell, 6th Duke of Bedford. [4]

Senecio is a genus of the daisy family (Asteraceae) that includes ragworts and groundsels. The scientific Latin genus name, Senecio, means "old man."

<i>Hakea</i> Genus of plants in the family Proteaceae endemic to Australia

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.

<i>Persoonia</i> genus of shrubs and small trees in the family Proteaceae

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.

<i>Baccharis</i> Genus of flowering plants

Baccharis is a genus of perennials and shrubs in the aster family (Asteraceae). They are commonly known as baccharises but sometimes referred to as "brooms", because many members have small thin leaves resembling the true brooms. They are not at all related to these however, but belong to an entirely different lineage of eudicots. B. halimifolia is commonly known as "groundsel bush", however true groundsels are found in the genus Senecio.

<i>Isopogon</i>

Isopogon, commonly known as conesticks, conebushes or coneflowers, is a genus of about forty species of flowering plants in the family Proteaceae, and are endemic to Australia. They are shrubs with rigid leaves, bisexual flowers in a dense spike or "cone" and the fruit is a small, hairy nut.

<i>Platylobium</i> Genus of legumes

Platylobium is a genus of shrubs in the family Fabaceae. Native to south eastern Australia, they occur in a range of habitats of the coastal regions. The genus was first described by James Edward Smith, and is closely allied to Bossiaea, another genus within the Mirbelioids.

<i>Comesperma</i>

It was defined by the French botanist Jacques Labillardière in his 1806 work Novae Hollandiae Plantarum Specimen. The genus name is derived from the Ancient Greek words come ("hair") and sperma ("seed"), and relates to the seeds bearing tufts of hair. The genus is distributed over southern Australia, particularly in the southwest of Western Australia, where 19 species are found. 24 species have been described.

<i>Senecio angulatus</i> Species of flowering plant in the daisy family Asteraceae

Senecio angulatus, also known as creeping groundsel and sometimes as Cape ivy, is a succulent plant from the family Asteraceae of the genus Senecio that is native to South Africa. It is a scrambling and a twining herb that can become an aggressive weed once established, making it an invasive species in some countries. However, it is grown as an ornamental plant for its satiny foliage and sweet-scented flowers.

The natural range of distribution on the mainland is from the Otway Ranges and Wilsons Promontory in the far south east of the Australian continent to Monga National Park near Braidwood, New South Wales. There is also an isolated occurrence in Tasmania on Cape Barren Island. Other common names are blanket bush, flannel leaf and tree blanketleaf.

<i>Adenanthos sericeus <span style="font-style:normal;">subsp.</span> sericeus</i> Subspecies of flowering plant

Adenanthos sericeus subsp. sericeus, commonly known as coastal woollybush, is a shrub native to the south coast of Western Australia.

<i>Hemiphora</i>

Hemiphora is a genus of five species of flowering plants in the mint family, Lamiaceae and is endemic to Western Australia. Plants in this genus are woolly shrubs with warty, hairy leaves and with five petals joined to form a tube-shaped flower with four stamens. These species are similar to those in the genus Chloanthes in that the base of the leaves extends down the stem. They differ from Chloanthes, in that the leaves only extend a short distance down the stem.
