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] |
Eremophila Jucunda
''Eremophila jucunda'' is a flowering plant in the figwort Family (biology), family, Scrophulariaceae and is Endemism, endemic to Western Australia. It is a small to medium-sized shrub with hairy branches and leaves, lance-shaped to egg-shaped leaves and cream-coloured, lilac or purple flowers. Description ''Eremophila jucunda'' is a small to medium shrub, depending on its habitat, growing to about tall on hard, stony clay to on hillsides. Its branches and leaves are covered with grey or lemon-yellow branched hairs, especially densely when young. The leaves are lance-shaped to egg-shaped, mostly long and wide. The flowers are borne singly in leaf axils on a stalk long covered in hairs similar to those on the leaves. There are 5 pale yellowish-green to purplish-brown, linear to lance-shaped sepals which are mostly long but which enlarge after flowering. The sepals are covered with hairs similar to those on the young leaves. The petals are long and are joined at their low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Sibirica
''Acacia sibirica'', commonly known as bastard mulga or false witchetty bush, is a tree or shrub belonging to the genus ''Acacia'' and the subgenus ''Juliflorae''. It is native to arid areas of Australia. Description The spreading tree or shrub typically grows to a height of with smooth fissured dark grey bark. The plant generally has a rounded or obconic habit with several stright to crooked, spreading main stems from the base with dense and spreading crown. The slightly shiny, glabrous, green to grey-green phyllodes are variable in shape and size They have a linear to narrowly oblong or narrowly elliptic shape and are in length with a width of about . The phyllodes are coriaceous and have an erect or spreading arrangement. The plant flowers between May and July but sometimes as late as September with Inflorescences that have rudimentary racemes which are scattered over the plants and not particularly showy. The spikes are bright golden with small flowers, that eventually form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Aneura
''Acacia aneura'', commonly known as mulga or true mulga, is a shrub or small tree native to arid outback areas of Australia. It is the dominant tree in the habitat to which it gives its name ( mulga) that occurs across much of inland Australia. Specific regions have been designated the Western Australian mulga shrublands in Western Australia and Mulga Lands in Queensland. Description Mulga trees are highly variable, in form, in height, and in shape of phyllodes and seed pods. They can form dense forests up to high, or small, almost heath-like low shrubs spread well apart. Most commonly, mulgas are tall shrubs. Because the mulga is so variable, its taxonomy has been studied extensively, and although ''A. aneura'' is likely to be split into several species eventually, there is as yet no consensus on how or even if this should be done. Although generally small in size, mulgas are long-lived, a typical life span for a tree undisturbed by fire is of the order of 200 to 300 yea ...

Ironstone
Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore compound from which iron (Fe) can be smelted commercially. Not to be confused with native or telluric iron, which is very rare and found in metallic form, the term ''ironstone'' is customarily restricted to hard, coarsely banded, non-banded, and non-cherty sedimentary rocks of post-Precambrian age. The Precambrian deposits, which have a different origin, are generally known as banded iron formations. The iron minerals comprising ironstones can consist either of oxides, i.e. limonite, hematite, and magnetite; carbonates, i.e. siderite; silicates, i.e. chamosite; or some combination of these minerals.U.S. Bureau of Mines Staff (1996) ''Dictionary of Mining, Mineral, & Related Terms.''
