Eucalyptus Lehmannii
''Eucalyptus lehmannii'', commonly known as bushy yate, is a eucalypt in the myrtle family Myrtaceae endemic to the south-west of Western Australia. It is a small tree with an oval, spreading form and dense foliage which sometimes reaches to the ground. It is widely cultivated in Australia and the United States because of its ornamental shape and decorative flowers, buds and fruit. There has been some confusion about its classification because of its ability to hybridise. Description ''Eucalyptus lehmannii'' is a sometimes multi-trunked mallee with smooth bark which is whitish grey to grey-brown and orange-brown and which sheds in strips. The stems of young plants are initially triangular in cross-section with leaves that are alternate, oblong to elliptical or lance-shaped, 5–8 cm long and 1–3 cm wide, glossy green on the upper surface and dull blue-green below. Older stems are smooth and round with alternate leaves. The adult leaves have a petiole 0.1&nd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ravensthorpe, Western Australia
Ravensthorpe is a town 541 km south-east of Perth and 40 km inland from the south coast of Western Australia. It is the seat of government of the Shire of Ravensthorpe. At the , Ravensthorpe had a population of 438. In 1848, the area was surveyed by Surveyor General John Septimus Roe who named many of the geographical features nearby, including the nearby Ravensthorpe Range that the later town was named after. There was one of the Western Australian Government Railways isolated branch lines between Hopetoun and Ravensthorpe. This line opened in 1909. Alluvial gold was discovered at the Phillips River in 1892. At the goldfield a ''de facto'' town emerged, known as ''Phillips River''. The government completed construction of a copper and gold smelter about 2 km south east of the town in 1906, used to cast copper and gold ingots. History A temporary pastoral lease ("Free Run") was registered by James Dunn senior in 1868. His five sons and daughter started she ...

Flora Australiensis
''Flora Australiensis: a description of the plants of the Australian Territory'', more commonly referred to as ''Flora Australiensis'', and also known by its standard abbreviation ''Fl. Austral.'', is a seven-volume flora of Australia published between 1863 and 1878 by George Bentham, with the assistance of Ferdinand von Mueller. It was one of the famous Kew series of colonial floras, and the first flora of any large continental area that had ever been finished. In total the flora included descriptions of 8125 species.Orchard, A. E. 1999. Introduction. In A. E. Orchard, ed. ''Flora of Australia - Volume 1'', 2nd edition pp 1-9. Australian Biological Resources Study Bentham prepared the flora from Kew; with Mueller, the first plant taxonomist residing permanently in Australia, loaning the entire collection of the National Herbarium of Victoria to Bentham over the course of several years. Mueller had been dissuaded from preparing a flora from Australia while in Australia by Bentham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Arborella
''Eucalyptus arborella'', commonly known as Twertup mallet, is a mallet or small tree that is endemic to a small area in the south-west of Western Australia.

It has smooth pale grey and whitish bark. Adult leaves are linear to narrow oblong, the same shade of glossy green on both sides, long and wide, tapering to a petiole long. The flower buds are arranged in leaf axils in clusters of between about twenty and fifty, the buds joined at the base on a cylindrical peduncle long. The individual buds are about wide, each with a narrow, more or less straight operculum long. Flowering has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Cornuta
''Eucalyptus cornuta'', commonly known as yate, is a tree species, sometimes a mallee and is endemic to the southwest of Western Australia. It has rough, fibrous bark on all or most of its trunk, smooth bark above, mostly lance-shaped adult leaves, elongated flower buds in groups of eleven or more, yellowish flowers and cylindrical to cup-shaped fruit. It is widely cultivated and produces one of the hardest and strongest timbers in the world. Description ''Eucalyptus cornuta'' is a tree that typically grows to a height of with a crown wide, sometimes a mallee to , and forms a lignotuber. New stems may fork out from the trunk or the lignotuber or multiple main stems may replace a single trunk in older specimens. It has rough, fibrous, brown to almost black bark on all or part of its trunk, smooth greyish bark above. Young plants and coppice regrowth have egg-shaped to more or less round leaves long, wide and paler on the lower surface. Adult leaves are arranged alternate ...

Pith
Pith, or medulla, is a tissue in the stem Stem or STEM may refer to: Plant structures * Plant stem, a plant's aboveground axis, made of vascular tissue, off which leaves and flowers hang * Stipe (botany), a stalk to support some other structure * Stipe (mycology), the stem of a mushro ...s of vascular plants. Pith is composed of soft, spongy ground tissue#Parenchyma, parenchyma cells, which in some cases can store starch. In eudicotyledons, pith is located in the center of the stem. In monocotyledons, it extends also into flowering stems and roots. The pith is encircled by a ring of xylem; the xylem, in turn, is encircled by a ring of phloem. While new pith growth is usually white or pale in color, as the tissue ages it commonly darkens to a deeper brown color. In trees pith is generally present in young growth, but in the trunk and older branches the pith often gets replaced – in great part – by xylem. In some plants, the pith in the middle of the stem may dry out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gland (botany)
In plants, a gland is defined functionally as a plant structure which secretes one or more products. This may be located on or near the plant surface and secrete externally, or be internal to the plant and secrete into a canal or reservoir. Examples include glandular hairs, nectaries, hydathodes, and the resin canals in Pinus. Notable examples Salt glands of the mangrove The salt glands of mangroves such as '' Acanthus'', ''Aegiceras'', ''Aegialitis'' and ''Avicennia'' are a distinctive multicellular trichome, a glandular hair found on the upper leaf surface and much more densely in the abaxial indumentum. On the upper leaf surface they are sunken in shallow pits, and on the lower surface they occur scattered among long nonglandular hairs composed of three or four cells. Development of the glands resembles that of the nonglandular hairs until the three-celled stage, when the short middle stalk cell appears. The salt gland continues to develop to produce two to four vacuola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamen
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 ''sporangium, 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 (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Cotyledon
A cotyledon (; ; ; , gen. (), ) is a significant part of the embryo within the seed of a plant, and is defined as "the embryonic leaf in seed-bearing plants, one or more of which are the first to appear from a germinating seed." The number of cotyledons present is one characteristic used by botanists to classify the flowering plants (angiosperms). Species with one cotyledon are called monocotyledonous ("monocots"). Plants with two embryonic leaves are termed dicotyledonous ("dicots"). In the case of dicot seedlings whose cotyledons are photosynthetic, the cotyledons are functionally similar to leaves. However, true leaves and cotyledons are developmentally distinct. Cotyledons are formed during embryogenesis, along with the root and shoot meristems, and are therefore present in the seed prior to germination. True leaves, however, are formed post-embryonically (i.e. after germination) from the shoot apical meristem, which is responsible for generating subsequent aerial por ...
