Calytrix Gomphrenoides
''Calytrix gomphrenoides'' is a species of flowering plant in the myrtle family Myrtaceae and is endemic to the Kimberley region of Western Australia. It is a glabrous, multi-stemmed shrub with linear leaves and white flowers turning pink as they age, with 16 to 18 stamens in a single row. Description ''Calytrix gomphrenoides'' is a glabrous, multistemmed shrub that typically grows to a height of up to and has linear leaves that are mostly long and wide on a petiole long. There are stipules up to long at the base of the petioles. The flowers are borne in dense heads of 15 to 40 flowers on the ends of branches on a peduncle about long. There are papery bracteoles long and wide, but that fall off after the flowers open. The floral tube is long, almost free from the style and has 10 ribs. The sepals are joined at the base, more or less round to egg-shaped, long, excludiong an awn long. The petals are white, turning pink on the outside with a dark red base, narrowly egg- ...

Lyndley Craven
Lyndley Alan Craven (3 September 1945 – 11 July 2014) was a botanist who became the Principal Research Scientist of the Australian National Herbarium. Lyndley ("Lyn") Craven worked for the Commonwealth Scientific and Industrial Research Organisation, CSIRO plant taxonomy unit of the New Guinea Survey Group, Division of Land Research and Regional Survey from 1964 to 1967. This was part of a unit that became the Australian National Herbarium, Centre for Australian National Biodiversity Research. Craven's duties included botanical support for land resources surveys. Craven then left to study horticulture at Burnley College (Australia), Burnley Horticultural College, Victoria (Australia), Victoria, earning the degree of Diploma of Horticultural Science in 1970 before being briefly employed by the Parks and Gardens Branch of Department of the Interior, Canberra. Part of this department later became the Canberra Botanic Garden and eventually the Australian National Herbarium, Centre ...

Awn (botany)
An awn is a hairy or bristle-like growth on a plant. On the seeds of grasses such as barley or rye, they form foxtails which assist seed dispersal by being barbed and so sticking to passing animals. Also, the awns may twist or curl as they are wetted and dry out and this action can make fallen seeds walk until they fall into a crevice into which they then burrow. Besides grasses, other families of plants which have awns include Asteraceae such as sunflowers and Geraniaceae such as geraniums. In the latter, the awns help disperse the seeds by developing a tension which then catapults the seeds when the seed head ripens and dries out. Description In grasses, awns typically extend from the lemmas of the florets. This often makes the hairy appearance of the grass synflorescence. Awns may be long (several centimeters) or short, straight or curved, single or multiple per floret. Some biological genera are named after their awns, such as the three-awns (''Aristida''). In s ...

Flora Of Western Australia
The flora of Western Australia comprises 10,842 published native vascular plant species and a further 1,030 unpublished species. They occur within 1,543 genus, genera from 211 Family (biology), families; there are also 1,335 naturalised alien or invasive plant species more commonly known as weeds. There are an estimated 150,000 cryptogam species or nonvascular plants which include lichens, and fungi although only 1,786 species have been published, with 948 algae and 672 lichen the majority. History Indigenous Australians have a long history with the flora of Western Australia. They have for over 50,000 years obtained detailed information on most plants. The information includes its uses as sources for food, shelter, tools and medicine. As Indigenous Australians passed the knowledge along orally or by example, most of this information has been lost, along many of the names they gave the flora. It was not until Europeans started to explore Western Australia that systematic written de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calytrix
''Calytrix'' is a genus of about 83 species of flowering plants, commonly known as star flowers, in the family Myrtaceae and is endemic to Australia. Plants in the genus ''Calytrix'' are small to large shrubs with small, spreading and more or less round leaves, the flowers arranged singly in leaf axils. The flowers are Monoicy, bisexual with 5 overlapping sepals with a long Awn (botany), awn, and many stamens. Description Plants in the genus ''Calytrix'' are dwarf to large shrubs with overlapping or widely-spaced leaves, but with stipules absent or small. The flowers are arranged singly in leaf axils with 2 Bract#Bracteole, bracteoles at the base. The Hypanthium, floral tube is usually long and tube-shaped with 5 overlapping sepals with a long awn on the end and 5 lance-shaped to elliptic petals that are free from each other and fall from the flower as it develops. There are many stamens, in one to several Whorl (botany), whorls. The fruit is a small, dry Nut (fruit), nut conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 2009
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperm ...
