Petrophile is a genus of evergreen shrubs, in the family Proteaceae. The genus is endemic to Australia. Commonly known as conebushes, [3] they typically have prickly, divided foliage and produce prominently-displayed pink, yellow or cream flowers followed by grey, conical fruits. [4]
The genus Petrophile was first formally described in 1809 by Joseph Knight in On the cultivation of the plants belonging to the natural order of Proteeae , preempting publication of the same name by Robert Brown in his book On the natural order of plants called Proteaceae . [5] [6]
The name Petrophile is derived from the Greek words petra = rock and philos = seeking or preferring, referring to the rocky habitat in which some species grow. [7]
The following is a list of Petrophile species and subspecies accepted by the Australian Plant Census as at November 2020: [2]
Species within this genus predominantly occur in Western Australia, but several species are found in other states including South Australia, New South Wales and Queensland. [8]
Plants in this genus, particularly those from Western Australia, require a freely draining soil. They tolerate periods of dryness and mild frosts and will grow well in full sun or part shade. They can be propagated from cuttings taken in autumn or from seed, however the production of new plants by either method can be slow. [4] [9]
Hakea is a genus of about 150 species of 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 being found in the south west of Western Australia.
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 the south-west of Western 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.
Pimelea, commonly known as rice flowers, is a genus of plants belonging to the family Thymelaeaceae. There are about 150 species, including 110 in Australia and 36 in New Zealand.
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.
Xylomelum is a genus of six species of flowering plants, often commonly known as woody pears, in the family Proteaceae and are endemic to Australia. Plants in this genus are tall shrubs or small trees with leaves arranged in opposite pairs, relatively small flowers arranged in spike-like groups, and the fruit a woody, more or less pear-shaped follicle.
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.
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.
Mirbelia is a plant genus belonging to the family Fabaceae and is endemic to Australia, occurring in every mainland state except South Australia. Plants in the genus Mirbelia are prickly, perennial shrubs with simple, sometimes sharply-pointed leaves, or the leaves absent. The flowers are arranged singly or in groups in leaf axils or on the ends of branches, the sepals joined at the base with five teeth. The petals are usually red, orange, purplish or bluish and the fruit is an inflated pod.
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.
Cryptandra is a genus of flowering plants in the family Rhamnaceae and is endemic to Australia. Most plants in the genus Cryptandra are spiny, heath-like shrubs with small, clustered leaves and flowers crowded at the ends of branches, the flowers are usually small, surrounded by brown bracts, and with tube-shaped hypanthium, the petals hooded over the anthers.
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.
Styphelia is a genus of shrubs in the family Ericaceae, native from Indo-China through the Pacific to Australia. Most have minute or small leaves with a sharp tip, single, tube-shaped flowers arranged in leaf axils and with the ends of the petals rolled back with hairs in the inside of the tube.
Petrophile conifera is a species of flowering plant in the family Proteaceae and is endemic to southwestern Western Australia. It is a bushy, much-branched shrub with pinnate, sharply-pointed leaves, and oval heads of hairy, cream-coloured to yellowish white flowers.
Petrophile filifolia is a species of flowering plant in the family Proteaceae and is endemic to southwestern Western Australia. It is a small shrub with curved, long, needle-shaped leaves and more or less spherical heads of hairy cream-coloured to pale yellow flowers.
