Calectasia Pignattiana
''Calectasia pignattiana'', commonly known as the stilted tinsel lily or Pignatti's star of Bethlehem, is a plant in the family Dasypogonaceae growing as a perennial herb and is endemic to the south–west of Western Australia. It is only known from ten locations, four of which are on road verges. The species is classified as vulnerable. Description ''Calectasia pignattiana'' is a prickly, rhizomatous herb growing to a height of about 50 cm. Unlike some other members of the genus (such as '' C. grandiflora'') this species lacks a rhizome but has stilt roots 10–60 mm long. The stems are up to 60 cm long and slender, with many lateral branches, occasionally with adventitious stilt roots up to 150 mm long protruding from the upper branches. The leaves are 5.2–11.5 x 0.9–1.4 mm and glabrous. The six petals are dark blue, gradually fading to white with age and the central anthers are yellow, turning orange-red with age. Flowers appear ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commelinids Of Australia
In plant taxonomy, commelinids (originally commelinoids) (plural, not capitalised) is a clade of flowering plants within the monocots, distinguished by having cell walls containing ferulic acid. The commelinids are the only clade that the APG IV system has informally named within the monocots. The remaining monocots are a paraphyletic unit. Also known as the commelinid monocots it forms one of three groupings within the monocots, and the final branch; the other two groups are the alismatid monocots and the lilioid monocots. Description Members of the commelinid clade have cell walls containing UV-fluorescent ferulic acid. Taxonomy The commelinids were first recognized as a formal group in 1967 by Armen Takhtajan, who named them the Commelinidae and assigned them to a subclass of Liliopsida (monocots). The name was also used in the 1981 Cronquist system. However, by the release of his 1980 system of classification, Takhtajan had merged this subclass into a larger one, and no ...

Endemic Flora Of Western Australia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

European Rabbit
The European rabbit (''Oryctolagus cuniculus'') or coney is a species of rabbit native to the Iberian Peninsula (including Spain, Portugal, and southwestern France), western France, and the northern Atlas Mountains in northwest Africa. It has been widely introduced elsewhere, often with devastating effects on local biodiversity. Its decline in its native range due to myxomatosis, rabbit calicivirus, overhunting and habitat loss has caused the decline of the Iberian lynx (''Lynx pardinus'') and Spanish imperial eagle (''Aquila adalberti''). It is known as an invasive species because it has been introduced to countries on all continents with the exception of Antarctica, and has caused many problems within the environment and ecosystems; in particular, European rabbits in Australia have had a devastating impact, due in part to the lack of natural predators there. The European rabbit is well known for digging networks of burrows, called warrens, where it spends most of its tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kwongan
Kwongan is plant community found in south-western Western Australia. The name is a Bibbelmun (Noongar) Aboriginal term of wide geographical use defined by Beard (1976) as Kwongan has replaced other terms applied by European botanists such as sand-heide (Diels 1906) or sand heath (Gardner 1942), giving priority to the language of people who have lived continuously in the southwest for more than 50,000 years. Recent archeological evidence shows occupation of the Kwongan for at least 25,500 years. Thus, kwongan has come again into common usage for the Southwest Australian Floristic Region's shrubland vegetation and associated countryside, equivalent to South Africa's fynbos, California's chaparral, France's maquis and Chile's matorral as seen in these other regions of the world experiencing a Mediterranean climate. Etymology To reflect contemporary orthographies, linguists strictly spell kwongan as (Douglas 1976, Dench 1994), or (von Brandenstein 1988). As with so many oth ...

Quairading, Western Australia
Quairading is a Western Australian town located in the Wheatbelt region. It is the seat of government for the Shire of Quairading. History The town was named for Quairading Spring, derived from a local Aboriginal word recorded in 1872 by surveyor Alexander Forrest. The first European settler in the area is believed to be Stephen Parker, who settled in nearby York. From 1859 to 1863, his son Edward Parker cleared land east of York towards Dangin, before Edward's son Jonah took over Dangin and the surrounding area. Jonah Parker subdivided his property and made Dangin a private townsite, surrounded by his land. A Methodist, Jonah Parker banned alcohol in the town and these factors led to residents leaving Dangin. The Government made available new land in nearby Quairading, and gave settlers a block for free if they cleared the land and lived there for seven years. Many settlers took up the offer and moved into the area between 1903 and 1908. The Greenhills Road Board, estab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dasypogonaceae
Dasypogonaceae is a family of flowering plants, one that has not been commonly recognized by taxonomists; the plants it contains were usually included in the family Xanthorrhoeaceae. If valid, Dasypogonaceae includes four genera with 16 species. The 2016 APG IV system places the family in the order Arecales, after several studies revealed the family as a sister-family to Arecaceae. The earlier APG III (2009), APG II (2003), and the 1998 APG system all accepted the validity of the family, assigning it to the clade commelinids, but leaving it unplaced as to order. The commelinids are monocots, the broad group to which, in any event, these plant clearly belong. The family is endemic to Australia, and comprises 16 species in four genera. The best known representative is ''Kingia australis ''Kingia'' is a genus consisting of a single species, ''Kingia australis'', and belongs to the plant family Dasypogonaceae. The Aboriginal name bullanock is used as a common name for the plant. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calectasia
''Calectasia'' is a genus of about fifteen species of flowering plants in the family Dasypogonaceae and is endemic to south-western Australia. Plants is this genus are small, erect shrubs with branched stems covered by leaf sheaths. The flowers are star-shaped, lilac-blue to purple and arranged singly on the ends of short branchlets. Description Plants in the genus ''Calectasia'' are small, often rhizome-forming shrubs with erect, branched stems with sessile leaves arranged alternately along the stems, long and about wide, the base held closely against the stem and the tip pointed. The flowers are arranged singly on the ends of branchlets and are bisexual, the three sepals and three petals are similar to each other, and joined at the base forming a short tube but spreading, forming a star-like pattern with a metallic sheen. Six bright yellow or orange stamens form a tube in the centre of the flower with a thin style extending beyond the centre of the tube. Taxonomy The genus ...

Glabrousness (botany)
Glabrousness (from the Latin ''glaber'' meaning "bald", "hairless", "shaved", "smooth") is the technical term for a lack of hair, down, setae, trichomes or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescen ...
