Trochocarpa Gunnii
''Trochocarpa gunnii'', commonly known as sweet-scented trochocarpa or fragrant purpleberry, is a common rainforest understorey shrub from the plant family Ericaceae (formerly Epacridaceae) endemic to Tasmania. Description ''Trochocarpa gunnii'' is a densely branched understorey shrub, usually growing to 2-4m tall and spreading with twisting branches. Leaves grow alternately along the branches, arranged so that the shoot appears flattened. The leaves are small (6-10mm long) and oval-elliptical to oblong shaped, with a dark green adaxial (upper) surface and a lighter green abaxial (lower) surface. Leaves have 5-7 parallel veins running along the abaxial surface. ''T. gunnii'' has small, white, pink or red flowers, and is the only species in this genus with a glabrous corolla. The flowers are sweetly scented and arranged in short spikes near the ends of branches or in the axils of leaves of the previous year’s shoots. Flowers can be seen in the summer months of December to Mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Understory
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...

Phylogenetic Tree
A phylogenetic tree (also phylogeny or evolutionary tree Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA.) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a ''rooted'' phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. ''Unrooted'' trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ronald Campbell Gunn
Ronald Campbell Gunn, Fellow of the Royal Society, FRS, (4 April 1808 – 13 March 1881) was a South African-born Australian Botany, botanist and politician. Early life Gunn was born at Cape Town, Cape Colony, (now South Africa), the son of William Gunn, lieutenant in the 72nd Regiment of Foot, 72nd Regiment, and his wife Margaret, ''née'' Wilson. Gunn accompanied his father to Mauritius, the West Indies, and Scotland where he was educated. Gunn was given an appointment in the Royal Engineers at Barbados, but left there in 1829 to go to Van Diemen's Land (now Tasmania), where he obtained the position of superintendent of convict barracks at Hobart Town. Career In 1830 Gunn became superintendent of convicts for North Tasmania at Launceston, Tasmania, Launceston. In 1831 Gunn became acquainted with an early Tasmanian botanist, Robert William Lawrence (1807–1833), who encouraged his interest in botany and placed him in touch with Sir William Jackson Hooker and Dr Lindley, with ...

Mount Field National Park
Mount Field National Park is a national park in Tasmania, Australia, 64 km northwest of Hobart. The landscape ranges from eucalyptus temperate rainforest to alpine moorland, rising to 1,434 metres (4,705 ft) at the summit of Mount Field West. History Mount Field National Park was founded in 1916, making it, along with Freycinet National Park, Tasmania's oldest national park. The area around Russell Falls has been protected for its natural beauty since 1885, when it was set aside as Tasmania's first nature reserve. The last known wild thylacine was captured in the region in 1933. The reserve was called "National Park" before 1946, but was officially renamed to its present name in 1947. Etymology Mount Field National Park was named for Judge Barron Field, who visited Tasmania as an itinerant judge in 1819 and 1821. Geology During the Pleistocene period, a snowfield covered the top of the Mount Field plateau and fed glaciers in the surrounding valleys. A large, 12&nb ...

Cenarrhenes
''Cenarrhenes'' is a monytypic genus in the family Proteaceae containing the single species ''Cenarrhenes nitida'', known as the Port Arthur plum or native plum. ''Cenarrhenes nitida'' is an evergreen shrub to small tree endemic to the rainforests and scrublands of western Tasmania. It bears white flowers in late spring followed by the development of fleshy fruit. Taxonomy and naming The French naturalist and explorer Jacques Labillardière described ''Cenarrhenes nitida'' in 1805, from a location described as ''in capite Van Diemen'' (Tasmania). It still bears its common name today. The genus name is derived from the Ancient Greek words ''kenos'' "empty" and ''arrhen'' "male", referring to the four staminode-like hypogynous glands. The genus only bears the one species, its name the Latin adjective ''nitida'' "bright/shining", referring to its glossy leaves. Although it resembles the persoonias in appearance, it does not appear to be related to them. Instead, it has been group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anopterus Glandulosus
''Anopterus glandulosus'', commonly known as native laurel or Tasmanian laurel, is a species of shrub or small tree in the family Escalloniaceae. Endemic to south and southwestern Tasmania, ''A. glandulosus'' is widespread in the moist understoreys of Tasmanian temperate rainforests and wet sclerophyll forests from sea level to mountainous regions below above sea level.Curtis WM & Morris DI 1993, ''The student’s flora of Tasmania'', 2nd edn St David’s Park publishing, Hobart, Tasmania. Taxonomy The name '' Anopterus'' comes from the Ancient Greek words ''ano'' (upwards) and ''pteron'' (wing), referring to its characteristic winged seeds, while ''glandulosus'' refers to the glandular tips present at the end of each leaf serration. The signature 'Labill' often appears after the Latin name of this species as it was first described by Jacques Labillardière in 1805. It is one of two Tasmanian plants in the ancient Gondwanan family Escalloniaceae, the other plant being '' Tet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...
