Granitites intangendus is a species of flowering plant endemic to Western Australia. It is found on granite outcrops in semi-arid regions of the midwest and south.
The only member of the genus Granitites, a name derived from its habitat, it is placed within the family Rhamnaceae. [1] It bears many similarities to the genus Alphitonia (Ash or Sarsparilla trees), which are found in distant tropical regions of Australia, suggesting that it is an ancient species that became relics by climate changes. Its lineage would therefore extend to an era, some 20 mya, when tropical species covered the southern part of the continent. [2]
The habit of this shrub is low-lying and sprawling, at 0.1 metres tall, or erect to a height of 2 metres. It has spiky branchlets, small leaves in an alternate arrangement, and small flowers that are clustered on relatively long stalks. The leaves are entire, or with a toothed margin, are linear in outline or broader at the base, may have hairs, veins that branch from the central axis, and are rolled upon themselves in a revolute manner. The flowers are generally white, the calyx and corolla might also be this colour or pinkish. Its fruit is a schizocarp, dry carpels that divide when mature into single seed bearing capsules. [3] It is found in sandy soils on granite outcrops east of Kalgoorlie, the Avon Wheatbelt and Mallee regions in the southern and eastern parts of the state. [4] Specimens have been recorded at The Humps near Hyden. [2]
The first description of the genus was made by Barbara Rye in Nuytsia in 1996. [5] The author refers to the specimens collected at Fraser's Range and Esperance Bay 120 years beforehand, which was described as a species of Pomaderris [6] by Ferdinand von Mueller. [7]
Spyridium globulosum, commonly known as basket bush, is a species of flowering plant in the family Rhamnaceae and is endemic to coastal areas in the south-west of Western Australia. It is a shrub with relatively large leaves and heads of flowers covered with whitish hairs.
Muellerolimon salicorniaceum, the sole species in genus Muellerolimon, is a succulent perennial herb or shrub that grows on salt mudflats in Western Australia.
Cryptandra arbutiflora, commonly known as waxy cryptandra, is a species of flowering plant in the family Rhamnaceae and is endemic to the southwest of Western Australia. It is a shrub with spiny branches, elliptic to linear leaves and tube-shaped white flowers.
Pomaderris paniculosa, commonly known as scurfy pomaderris, is a species of flowering plant in the family Rhamnaceae and is native to Australia and New Zealand. It is a shrub with hairy branchlets, round to elliptic or egg-shaped leaves with the narrower end towards the base and panicles of hairy, cream-coloured to greenish, sometimes crimson-tinged flowers.
Micromyrtus elobata is a species of flowering plant in the myrtle family, Myrtaceae and is endemic to the south of Western Australia. It is usually an erect shrub with small, narrowly to broadly egg-shaped leaves with the narrower end towards the base, and white flowers 3–5 mm (0.12–0.20 in) in diameter.
Enekbatus cryptandroides is a shrub endemic to Western Australia.
Pomaderris brevifolia is a species of flowering plant in the family Rhamnaceae and is endemic to the south of Western Australia. It is a slender shrub with silky-hairy young branchlets, wedge-shaped, heart-shaped or egg-shaped leaves with the narrower end towards the base, and clusters of ten to twenty cream-coloured to pale pink flowers.
Pomaderris grandis, commonly known as large pomaderris, is a species of flowering plant in the family Rhamnaceae and is endemic to a restricted part of the south-west of Western Australia. It is an erect shrub that typically grows to a height of 30–75 cm (12–30 in) and produces white flowers from July to October. It grows in rocky gullies on the slopes of Mount Manypeaks in the Esperance Plains biogeographic region of south-western Western Australia. The species was first formally described in 1862 by Ferdinand von Mueller in his Fragmenta Phytographiae Australiae. It is listed as "Priority Four" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, meaning that it is rare or near threatened.
Pomaderris myrtilloides is a species of flowering plant in the family Rhamnaceae and is endemic to near-coastal areas of southern Western Australia. It is an erect shrub with many branches, narrowly egg-shaped elliptic or wedge-shaped leaves with the narrower end towards the base, and cream-coloured to pale pink flowers.
Pomaderris rotundifolia is a species of flowering plant in the family Rhamnaceae and is endemic to Western Australia. It is an upright, spreading shrub that typically grows to a height of 0.1–1.5 m, its branchlets covered with star-shaped hairs. The leaves are more or less round leaves and the flowers are white to pink. In most respects it is similar to other species of Pomaderris occurring in Western Australia but has more prominent bracts, shorter pedicels and well-developed petals. Flowering occurs from June to October.
Spyridium oligocephalum is a species of flowering plant in the family Rhamnaceae and is endemic to the south-west of Western Australia. It is a shrub that typically grows to a height of 0.6–1.5 m, its leaves glabrous except when very young. There are large, papery, orange-brown stipules joined in pairs at their bases, at the base of the petiole. The flowers are arranged in head-like, condensed cymes on the ends of branchlets. The sepals are about 1 mm (0.039 in) long and densely covered with hairs 0.3–0.5 mm (0.012–0.020 in) long.
