Novae Hollandiae Plantarum Specimen
''Novae Hollandiae Plantarum Specimen'' is a two-volume work describing the flora of Australia. Facsimiles of the originals can be found in the onlinBiodiversity Heritage Library (Vol.1)anVol 2) The author was the French botanist Jacques Labillardière, who visited the region in 1792 with the d'Entrecasteaux expedition. Published between 1804 and 1806, it is one of the earliest works to describe the plants of the continent; according to Denis and Maisie Carr, " practical terms, this was the first general flora of Australia." The work describes the botanical collections made by himself and his companion on the d'Entrecasteaux expedition, Charles Riche, and the unattributed and later collections of Nicolas Baudin's expedition. Labillardière's collections were seized by the English, but were returned to him in France at the intervention of Joseph Banks. He made his collections at Observatory Island and other locations at the Archipelago of the Recherche. Extensive collection were ...

Novae Hollandiae Plantarum Specimen Title
A nova (plural novae or novas) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star (hence the name "nova", which is Latin for "new") that slowly fades over weeks or months. Causes of the dramatic appearance of a nova vary, depending on the circumstances of the two progenitor stars. All observed novae involve white dwarfs in close binary systems. The main sub-classes of novae are classical novae, recurrent novae (RNe), and dwarf novae. They are all considered to be cataclysmic variable stars. Classical nova eruptions are the most common type. They are likely created in a close binary star system consisting of a white dwarf and either a main sequence, subgiant, or red giant star. When the orbital period falls in the range of several days to one day, the white dwarf is close enough to its companion star to start drawing accreted matter onto the surface of the white dwarf, which creates a dense but shallow atmosphere. This atmospher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intaglio Printing
Intaglio ( ; ) is the family of printing and printmaking techniques in which the image is incised into a surface and the incised line or sunken area holds the ink. It is the direct opposite of a relief print where the parts of the matrix that make the image stand ''above'' the main surface. Normally, copper or in recent times zinc sheets, called plates, are used as a surface or matrix, and the incisions are created by etching, engraving, drypoint, aquatint or mezzotint, often in combination. Collagraphs may also be printed as intaglio plates. After the decline of the main relief technique of woodcut around 1550, the intaglio techniques dominated both artistic printmaking as well as most types of illustration and popular prints until the mid 19th century. Process In intaglio printing, the lines to be printed are cut into a metal (e.g. copper) plate by means either of a cutting tool called a burin, held in the hand – in which case the process is called ''engraving''; or thr ...

Adenanthos
''Adenanthos'' is a genus of Australian native shrubs in the flowering plant family Proteaceae. Variable in habit and leaf shape, it is the only genus in the family where solitary flowers are the norm. It was discovered in 1791, and formally published by Jacques Labillardière in 1805. The type species is ''Adenanthos cuneatus'', and 33 species are recognised. The genus is placed in subfamily Proteoideae, and is held to be most closely related to several South African genera. Endemic to Australia, its centre of diversity is southwest Western Australia, where 31 species occur. The other two species occur in South Australia and western Victoria (Australia). They are mainly pollinated by birds. Description Habit The growth habits of ''Adenanthos'' species range from prostrate shrubs to small trees, with most species occurring as erect shrubs. There are two basic growth forms. Plants that lack a lignotuber have a single stem. Such plants usually grow into fairly erect shrubs; and so ...

Cephalotus Follicularis
''Cephalotus'' ( or ; Greek: ''κεφαλή'' "head", and ''οὔς''/''ὠτός'' "ear", to describe the head of the anthers) is a genus which contains one species, ''Cephalotus follicularis'' the Albany pitcher plant, a small carnivorous pitcher plant. The pit-fall traps of the modified leaves have inspired the common names for this plant, which include 'Albany pitcher plant", "Western Australian pitcher plant", "Australian pitcher plant", or "fly-catcher plant." It is an evergreen herb that is endemic to peaty swamps in the southwestern corner of Western Australia. Description ''Cephalotus follicularis'' is a small, low growing, herbaceous species. Evergreen leaves appear from underground rhizomes, are simple with an entire leaf blade, and lie close to the ground. The insectivorous leaves are small and have the appearance of moccasins, forming the 'pitcher' of the common name. The pitchers develop a dark red colour in high light levels but stay green in shadier conditions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prodromus Florae Novae Hollandiae Et Insulae Van Diemen
''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'' (Prodromus of the Flora of New Holland and Van Diemen's Land) is a flora of Australia written by botanist Robert Brown and published in 1810. Often referred to as ''Prodromus Flora Novae Hollandiae'', or by its standard botanical abbreviation ''Prodr. Fl. Nov. Holland.'', it was the first attempt at a survey of the Australian flora. It described over 2040 species, over half of which were published for the first time. Brown's ''Prodromus'' was originally published as Volume One, and following the ''Praemonenda'' (Preface), page numbering commences on page 145. Sales of the ''Prodromus'' were so poor, however, that Brown withdrew it from sale. Due to the commercial failure of the first volume, pages 1 to 144 were never issued, and Brown never produced the additional volumes that he had planned. In 1813, a book of illustrations for the ''Prodromus'' was published separately by Ferdinand Bauer under the title ''Ferdinandi Ba ...
