Daphnandra Apatela
''Daphnandra apatela'', the socketwood, light yellowwood or canary socketwood is a common rainforest tree in eastern Australia. It grows in the more fertile alluvial soils and basaltic soils. Distributed from the Watagan Mountains (31° S) in New South Wales to Miriam Vale (24° S) near Gladstone in Queensland. Naming & taxonomy A member of the ancient Gondwana family Atherospermataceae. Formerly considered '' Daphnandra micrantha'', the Australian socketwood. Recently it has been recognised as a separate species, as published by Richard Schodde. The generic name Daphnandra refers to a similarity of the anthers of the Bay Laurel. Greek ''daphne'' refers to the Bay Laurel, and ''andros'' from the Greek for man. The species name apatela is from the Greek to deceive, because of the similarity to Daphnandra micrantha. A feature where larger branchlets meet the main trunk resembles a "ball and socket" type joint. Hence the common name of ''Socketwood''. Canary Socketwood or ...

Martinsville, New South Wales
Martinsville is a small town near Morisset and west of Lake Macquarie in New South Wales, Australia. It is part of the West Ward of the City of Lake Macquarie local government area. It was first settled by Europeans between 1861 and 1866. The first industry in the area was timber. The public school opened in 1878, but this was eventually closed and pupils transferred to Cooranbong Community School. The town sits in a small valley at the base of the Watagan Mountains.

Atherospermataceae
The Atherospermataceae, commonly known as the southern sassafrases, are a family of broadleaf evergreen trees and shrubs. The family includes 14 species in seven genera. The atherosperms are today mostly distributed in the Southern Hemisphere, with two species native to southern Chile and 12 species native to Australasia. Wood is commercially harvested from rainforest species of this family, and is used both in construction and in fine cabinet making. Ecology These trees and shrubs are characteristic of the lower strata of the tropical rainforest, except '' Dryadodaphne'' species, which belong to the rainforest high canopy. The glands at the base of the stamens secrete nectar in ''Laurelia novae-zelandiae'', which accumulates at the base of the flower and attracts bees, beetles and bee flies. The seed, in the form of a feathery achene, is dispersed by wind (anemochory). The wood of ''Laurelia'' has local interest for construction, particularly the Chilean ''Laurelia sempervir ...

Trees Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 30,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae ('' Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the ...

Panicle
A panicle is a much-branched inflorescence. (softcover ). Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth. This type of inflorescence is largely characteristic of grasses such as oat and crabgrass, as well as other plants such as pistachio and mamoncillo. Botanists use the term paniculate in two ways: "having a true panicle inflorescence" as well as "having an inflorescence with the form but not necessarily the structure of a panicle". Corymb A corymb may have a paniculate branching structure, with the lower flowers having longer pedicels than the upper, thus giving a flattish top superficially resembling an umbel. Many species in the subfamily Amygdaloideae, such as hawthorns and rowans, produce their flowers in corymbs. up'' Sorbus glabrescens'' corymb with fruit See ...

Ball And Socket
The ball-and-socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The distal bone is capable of motion around an indefinite number of axes, which have one common center. This enables the joint to move in many directions. An enarthrosis is a special kind of spheroidal joint in which the socket covers the sphere beyond its equator.Platzer, Werner (2008) ''Color Atlas of Human Anatomy'', Volume 1p.28/ref> Examples Examples of this form of articulation are found in the hip, where the round head of the femur (ball) rests in the cup-like acetabulum (socket) of the pelvis; and in the shoulder joint, where the rounded upper extremity of the humerus (ball) rests in the cup-like glenoid fossa (socket) of the shoulder blade.And the phalanges (toes, fingers)Introduction to Joints: Synovial Joints - Ball and Socket Joints (The shoulder also includes a sternoclavicular joint ...

Strychnine
Strychnine (, , US chiefly ) is a highly toxic, colorless, bitter, crystalline alkaloid used as a pesticide, particularly for killing small vertebrates such as birds and rodents. Strychnine, when inhaled, swallowed, or absorbed through the eyes or mouth, causes poisoning which results in muscular convulsions and eventually death through asphyxia. While it is no longer used medicinally, it was used historically in small doses to strengthen muscle contractions, such as a heart and bowel stimulant and performance-enhancing drug. The most common source is from the seeds of the ''Strychnos nux-vomica'' tree. Biosynthesis Strychnine is a terpene indole alkaloid belonging to the ''Strychnos'' family of '' Corynanthe'' alkaloids, and it is derived from tryptamine and secologanin. The biosynthesis of strychine was solved in 2022. The enzyme, strictosidine synthase, catalyzes the condensation of tryptamine and secologanin, followed by a Pictet-Spengler reaction to form strictosidine ...

Lismore, New South Wales
Lismore is a city in northeastern New South Wales, Australia and the main population centre in the City of Lismore Local government in Australia, local government area; it is also a regional centre in the Northern Rivers region of the State. It is situated on a low flood plain on the banks of the Wilsons River (New South Wales), Wilsons River near the latter's junction with Leycester Creek, both tributaries of the Richmond River which enters the Pacific Ocean at Ballina, New South Wales, Ballina, to the east. The original settlement initially developed as a grazing property in the 1840s, then became a timber and agricultural town and inland port based around substantial river traffic, which prior to the development of the road and rail networks was the principal means of transportation in the region. Use of the river for transport declined and then ceased around the mid-twentieth century, however by that time Lismore (which was elevated to city status in 1946) had become well est ...

Bay Laurel
''Laurus nobilis'' is an aromatic evergreen tree or large shrub with green, glabrous (smooth) leaves. It is in the flowering plant family Lauraceae. It is native to the Mediterranean region and is used as bay leaf for seasoning in cooking. Its common names include bay tree (esp. United Kingdom), bay laurel, sweet bay, true laurel, Grecian laurel, or simply laurel. ''Laurus nobilis'' figures prominently in classical Greco-Roman culture. Worldwide, many other kinds of plants in diverse families are also called "bay" or "laurel", generally due to similarity of foliage or aroma to ''Laurus nobilis''. Description The laurel is an evergreen shrub or small tree, variable in size and sometimes reaching tall. The genus ''Laurus'' includes four accepted species, whose diagnostic key characters often overlap. The bay laurel is dioecious (unisexual), with male and female flowers on separate plants. Each flower is pale yellow-green, about diameter, and they are borne in pairs besid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthers
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in '' Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pan ...
