Asterella Drummondii
''Asterella drummondii'' is a liverwort in the family Aytoniaceae, which was first described as ''Fimbraria drummondii'' by Taylor in 1846, from material collected by Ronald Gunn Ronald Campbell Gunn, FRS, (4 April 1808 – 13 March 1881) was a South African-born Australian botanist and politician. Early life Gunn was born at Cape Town, Cape Colony, (now South Africa), the son of William Gunn, lieutenant in the Britis ... in Tasmania, and James Drummond (for whom it is named) in Western Australia from the Swan River. It is found in all states of Australia, in semi-arid areas. Description ''Asterella drummondii'' is a liverwort occurring on soil crusts or organic material in both wet and dry habitats. The thallus usually has a single tongue-like shape but sometimes appears as a star shaped rosette with a red/black margin, making the species easily found. When the thallus is dry, it rolls up to expose dark wavy margins. The fruiting bodies occur on dark stalks on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

James Drummond (botanist)
James Drummond (late 1786 or early 1787 – 26 March 1863) was an Australian botanist and naturalist who was an early settler in Western Australia. Early life James Drummond was born in Inverarity, near Forfar, Angus, Scotland, the eldest son of Thomas Drummond, a gardener and botanist. His younger brother Thomas Drummond (1793–1835) was also a botanist. The latter emigrated to Cuba and died there. Both brothers originally worked with their father on the Fothringham estate in Inverarity. He was baptised on 8 January 1787. His father, Thomas Drummond, was a gardener at Fotheringham estate. Little is known of his early life, but he certainly followed the usual course of apprenticeship leading to his "qualification" as a gardener. In 1808, he was employed by Mr Dickson (most probably George Dickson of Leith Walk, Edinburgh). In the mid-1808, Drummond (aged 21) he was appointed curator of the botanic garden that was being established by the Cork Institution, in the cit ...

Swan River (Western Australia)
The Swan River () is a river in the south west of Western Australia. The river runs through the metropolitan area of Perth, Western Australia's capital and largest city. Course of river The Swan River estuary flows through the city of Perth. Its lower reaches are relatively wide and deep, with few constrictions, while the upper reaches are usually quite narrow and shallow. The Swan River drains the Avon and coastal plain catchments, which have a total area of about . It has three major tributaries, the Avon River, Canning River and Helena River. The latter two have dams (Canning Dam and Mundaring Weir) which provide a sizeable part of the potable water requirements for Perth and the regions surrounding. The Avon River contributes the majority of the freshwater flow. The climate of the catchment is Mediterranean, with mild wet winters, hot dry summers, and the associated highly seasonal rainfall and flow regime. The Avon rises near Yealering, southeast of Perth: it meand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thallus
Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts (leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen record ...
