Achnophora tatei | |
Achnophora is a genus of flowering plants in the family Asteraceae described as a genus in 1883. [1] [2]
The only known species is Achnophora tatei. This is a rare endemic found only on Kangaroo Island in South Australia. [3]
The rhizome of A. tatei is described as thick, hairless and vertical with bundles of short thick rootlets attached. [4] [5]
Achnophora tatei leaves are in a rosette form at the base of the plant, with a long narrow leaf shape (linear) and sheath at the base of the leaf. [5]
Achnophora tatei flowers take the form of a scape (single flowering stem arising from the rhizome). [5] The flower stems are red, thread-like, almost naked and about as long as the leaves. [6] Flowers are one-headed, have a rosette of bracts (small leaf like structures) surrounding the flower (involucre) which are close to hemispheric (i.e. half of a sphere). [5]
The bracts of the flower are generally arranged in three rows of unequal length, with similar grades of size, and range in shape with the bract being egg-shaped with broader end at base (ovate) to the bract being egg-shaped with the narrow end at base (obovate). [5] The bracts are 4 to 5 millimetres long and have dry and membranous margins. [6]
The receptacle or floral axis has conspicuous oblong (having a length greater than width) scales between the flowers. [6]
The ray-flowers are female in 1 row, with about 25 ligules which are narrow, blue and are an estimated 10 millimetres long. [6]
Disc-flowers are tubular, with the style-branches being slender (capillary). [6]
Anthers (pollen bearing structure which is part of the stamen) are blunt and rounded (obtuse) at the base. [6]
Achnophora tatei is commonly known as the Kangaroo Island daisy. [7]
The genus name Achnophora is derived from the Greek word 'achne' which means chaff and 'phoros' meaning bearing. [7] This refers to the clearly visible scales of the receptacle and pappus. [7] Tatei is named after Ralph Tate (1840-1901), a British born botanist and geologist, who was a professor of Natural Science at the University of Adelaide. [7]
Achnophora tatei is found along the south coast of Kangaroo Island, South Australia. [6] The species is found in wet, swampy places. [6]
Achnophora tatei has been classified as a vulnerable species by the South Australian Government due to a restricted distribution and the impacts of increasing salinity. [7]
Calocephalus is a genus of flowering plants in the family Asteraceae. It is endemic to Australia, where it is represented in every state.
Bulbophyllum baileyi, commonly known as the fruit fly orchid, is a species of epiphytic or lithophytic orchid that is native to Queensland and New Guinea. It has coarse, creeping rhizomes, curved, yellowish pseudobulbs with a single thick, fleshy leaf, and a single cream-coloured flower with yellow, red or purple spots. It grows on trees and rocks in open forest, often in exposed places.
Dimorphocoma is a genus of flowering plants in the family Asteraceae.
Gymnarrhena is a deviant genus of plants in the family Asteraceae, with only one known species, Gymnarrhena micrantha. It is native to North Africa and the Middle East, as far east as Balochistan. Together with the very different Cavea tanguensis it constitutes the tribe Gymnarrheneae, and in the subfamily Gymnarrhenoideae.
Hymenonema is a genus of flowering plants in the family Asteraceae endemic to Greece. On each of the single or few stems, the species have one to three flowerheads consisting of yellow or yolk yellow ligulate florets, scaly pappus, greyish, pinnately segmented leaves in a basal rosette, and few smaller leaves on the 20–70 cm high stems. It contains two species: Hymenonema graecum, that is known from the Cyclades, and Hymenonema laconicum, which occurs in the central and south-eastern Peloponnesos.
Mairia is a genus of perennial herbaceous plants assigned to the family Asteraceae. All species have leathery, entire or toothed leaves in rosettes, directly from the underground rootstock, and one or few flower heads sit at the top of the stems that carry few bracts. These have a whorl of white to mauve ray florets surrounding yellow disc florets in the centre. In general, flowering only occurs after the vegetation has burned down. The six species currently assigned to Mairia are endemic to the Western Cape and Eastern Cape provinces of South Africa. Some of the species are called fire daisy in English and vuuraster in Afrikaans.
Corymbium is a genus of flowering plants in the daisy family comprising nine species. It is the only genus in the subfamily Corymbioideae and the tribe Corymbieae. The species have leaves with parallel veins, strongly reminiscent of monocots, in a rosette and compounded inflorescences may be compact or loosely composed racemes, panicles or corymbs. Remarkable for species in the daisy family, each flower head contains just one, bisexual, mauve, pink or white disc floret within a sheath consisting of just two large involucral bracts. The species are all endemic to the Cape Floristic Region of South Africa, where they are known as plampers.
Arthrochilus, commonly called elbow orchids, is a genus of about fifteen species of flowering plants from the orchid family (Orchidaceae) and is found in Australia and New Guinea. The flowers are pollinated by male thynnid wasps which attempt to mate with the flower and are held in place by hooks while the pollinium is transferred between insect and flower.
Lyperanthus, commonly known as beak orchids, is a genus of flowering plants from the orchid family, Orchidaceae, that is endemic to Australia. There are two species, one in Western Australia and the other in four eastern Australian states, distinguished by their single long, narrow, leathery leaf and dull coloured flowers which have prominent short calli on their labellum. Both form loose colonies which reproduce asexually from their tubers, and sexually using their flowers.
Atkinsonia is a hemi-parasitic shrub with oppositely set, entire leaves and yellowish, later rusty-red colored flowers, that is found in Eastern Australia. It is a monotypic genus, the only species being Atkinsonia ligustrina, and is assigned to the showy mistletoe family, Loranthaceae. It is sometimes called Louisa's mistletoe.
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.
Stenanthera is a genus of flowering plants in the family Ericaceae. Most are low shrubs with leaves that are paler on the lower surface, tube-shaped flowers and with the fruit a drupe. There are three species, formerly included in the genus Astroloma.
Myopordon pulchellum is a species of flowering plants in the tribe Cardueae within the family Asteraceae.
Mairia burchellii is a tufted perennial plant of up to 15 cm (6 in) assigned to the family Asteraceae. It has narrow leaves of up to 5 mm (0.20 in) wide, with single main vein and an entire margin. Flower heads only occur after a fire has destroyed the standing vegetation, mostly in November or between February and June. The flower heads sit individually or with a few on the tip of a purplish stalk, with a few narrow bracts, and consist of a row of pinkish ray florets around many yellow disc florets. It can be found in the southwest of the Western Cape province of South Africa.
Asterolasia phebalioides, commonly known as downy starbush, is a species of shrub in the family Rutaceae and is endemic to south-eastern continental Australia. It has densely crowded heart-shaped to wedge-shaped leaves densely covered with star-shaped hairs, and single yellow flowers borne on the ends of branchlets with star-shaped hairs on the back of the petals.
Teucrium betchei is a species of flowering plant in the family Lamiaceae, and is endemic to eastern Australia. It is a perennial herb or undershrub with rod-like stems, linear to very narrow lance-shaped leaves and white flowers.
Teucrium grandiusculum is a species of flowering plant in the family Lamiaceae and is endemic to central Australia. It is a perennial herb or shrub with toothed, egg-shaped leaves and white flowers.
Teucrium teucriiflorum is a species of flowering plant in the family Lamiaceae, and is endemic to arid and semi-arid areas of Australia. It is a semi-scandent shrub with many branches, linear to narrow lance-shaped or narrow egg-shaped leaves and creamy-white flowers.
Goodenia sepalosa is a species of flowering plant in the family Goodeniaceae and is endemic to northern Australia. It is a prostrate to ascending herb with narrow oblong to lance-shaped leaves, the narrower end towards the base, and racemes of yellow flowers.
Myosotis exarrhena is a species of flowering plant in the family Boraginaceae, endemic to Australia. Robert Brown described this species as Exarrhena suaveolens in 1810. Plants of this species of forget-me-not are perennial rosettes with ebracteate inflorescences and white corollas with exserted stamens.
