Acacia Thoma
''Acacia thoma'' is a shrub belonging to the genus ''Acacia'' and the subgenus ''Juliflorae'' that is endemic to arid areas of western Australia. Description The multi-stemmed and obconic shrub crowns sparse to sub-dense and typically grows to a height of with a width of . Bark on the upper branches is smooth and grey but becomes rough and longitudinally fissured at the base. It has light green new shoots with rudimentary caducous stipules that are resinous but not sticky. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The dull green to grey green, coriaceous, sub-rigid and erect phyllodes have a narrowly linear to narrowly elliptic shape and a length of and a width of . They are flat and straight to shallowly incurved with many parallel longitudinal fine nerves. Taxonomy The plant is named for Emil Thoma, a Botanical Advisor with Rio Tinto Iron Ore, who assisted Maslin and provided samples and information on the species. Distribution It is native ...

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. The species is known locally as moodjar and, more recently, the Christmas tree or Western Australian Christmas tree.

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] |
