Bruce Maslin
Bruce Roger Maslin (born 3 May 1946) is an Australian botanist, known for his work on ''Acacia'' taxonomy. Born in Bridgetown, Western Australia, he obtained an honours degree in botany from the University of Western Australia in 1967, then took up an appointment as a botanist with the Western Australian Herbarium. The following year he was conscripted to serve in the Vietnam War; he gave three years in National Service, serving in Vietnam in 1969. In 1970 he returned to his position at the Western Australian Herbarium, serving in that institution until 1987. During this time he was Australian Botanical Liaison Officer in 1977 and 1978; editor of ''Nuytsia ''Nuytsia floribunda'' is a hemiparasitic tree found in Western Australia.

Acacias Of Western Australia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Acacia Species
Several Cladistics, cladistic analyses have shown that the genus ''Acacia sensu lato, Acacia'' is not monophyletic. While the subg. ''Acacia'' and subg. ''Phyllodinae'' are monophyletic, subg. ''Aculeiferum'' is not. This subgenus consists of three clades. Therefore, the following list of ''Acacia'' species cannot be maintained as a single entity, and must either be split up, or broadened to include species previously not in the genus. This genus has been provisionally divided into 5 genus, genera, ''Acacia'', ''Vachellia'', ''Senegalia'', ''Acaciella'' and ''Mariosousa''. The proposed type species of ''Acacia'' is ''Acacia penninervis''. Which of these segregate genera is to retain the name ''Acacia'' has been controversial. The genus was previously typified with the African species ''Acacia scorpioides'' (L.) W.F.Wright, a synonym of ''Acacia nilotica'' (L.) Delile. Under the original typification, the name ''Acacia'' would stay with the group of species currently recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown Land
Crown land (sometimes spelled crownland), also known as royal domain, is a territorial area belonging to the monarch, who personifies the Crown. It is the equivalent of an entailed estate and passes with the monarchy, being inseparable from it. Today, in Commonwealth realms such as Canada and Australia, crown land is considered public land and is apart from the monarch's private estate. In Britain, the hereditary revenues of Crown lands provided income for the monarch until the start of the reign of George III, when the profits from the Crown Estate were surrendered to the Parliament of Great Britain in return for a fixed civil list payment. The monarch retains the income from the Duchy of Lancaster. Australia In Australia, public lands without a specific tenure (e.g. National Park or State Forest) are referred to as Crown land or State Land, which is described as being held in the "right of the Crown" of either an individual State or the Commonwealth of Australia; there is ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Pusilla
''Acacia pusilla'' is a shrub of the genus ''Acacia'' and the subgenus ''Phyllodineae'' the is endemic to south western Australia. Description The dome shaped shrub typically grows to a height of . It has decumbent and hairy branchlets with persistent, setaceous and recurved stipules with a length of . Like most species of ''Acacia'' it has phyllodes rather than true leaves. The crowded and grey-green and glabrous phyllodes are found on raised stem-projections and are patent to erect. The flat and linear phyllodes have a length of and a width of and are narrowed toward the base. It blooms from September to October and produces yellow flowers.

It was reclassified as ''Racosperma pusillum'' by Leslie Pedley in 2003 and transf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Laricina
''Acacia laricina'' is a shrub belonging to the genus ''Acacia'' and the subgenus ''Phyllodineae'' that is endemic to south western Australia. Description The shrub typically grows to a height of and can have a dense or spreading or domed habit.

Like most species of ''Acacia'' it has phyllodes rather than true leaves. The evergreen phyllodes are crowded and appear to be continuous with the branchlets. They are straight to shallowly curved with a pentagonal cross-section and a length and a width of with five prominent nerves. It produces cream-yellow flowers from October to November. The simple inflorescences occur singly in the axils an have sperical flower-heads that contain 17 to 30 cream to pale yellow coloured flowers. Following flowering thinly coriaceous seed pods are formed. The red-brown pods have a length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Phyllode
Phyllodes are modified petioles or leaf stems, which are leaf-like in appearance and function. In some plants, these become flattened and widened, while the leaf itself becomes reduced or vanishes altogether. Thus the phyllode comes to serve the purpose of the leaf. Some important examples are ''Euphorbia royleana'' which are cylindrical and '' Opuntia'' which are flattened. They are common in the genus ''Acacia'', especially the Australian species, at one time put in ''Acacia'' subg. ''Phyllodineae''. Sometimes, especially on younger plants, partially formed phyllodes bearing reduced leaves can be seen. The illustration (to the right) of ''Acacia suaveolens'' from ''Novae Hollandiae plantarum specimen'' shows the juvenile true leaves, together with the developing phyllodes, and the phyllodes of the mature plant. The genus, ''Daviesia'', in the family Fabaceae, is characterised in part by the plants having phyllodes. File:Acacia suaveolens 9064505997 9f14f5f117 o.jpg, ''Acacia ...
