Velvet Wattle
''Acacia fulva'', known colloquially as velvet wattle or soft wattle, is a species of ''Acacia'' native to eastern Australia. ''Acacia fulva'' grows as a shrub or tree, ranging anywhere from 1.5 to 15 m in height. Young trees have smooth grey-green bark, which darkens and becomes rough and fissured with age. New growth is covered in red-brown velvety hairs. The silver-grey leaves are pinnate, with 4-12 pairs of pinnae, each 3-7.5 cm long. Each pinna in turn is made up of 11 to 28 pairs of 3–10 mm-long pinnules. Flowering occurs from November till June, the yellow flowerheads arranged in axillary and terminal panicles or racemes. Each small round flower head is composed of 20 to 40 individual flowers. Flowering is followed by the development of the 2–12 cm-long leathery seed pods, which are ripe between April and November. Specimens of ''Acacia fulva'' were previously assigned to the species '' A. mollifolia'' until Mary Tindale described it as a separate spec ...

Fabales Of Australia
The Fabales are an order of flowering plants included in the rosid group of the eudicots in the Angiosperm Phylogeny Group II classification system. In the APG II circumscription, this order includes the families Fabaceae or legumes (including the subfamilies Caesalpinioideae, Mimosoideae, and Faboideae), Quillajaceae, Polygalaceae or milkworts (including the families Diclidantheraceae, Moutabeaceae, and Xanthophyllaceae), and Surianaceae. Under the Cronquist system and some other plant classification systems, the order Fabales contains only the family Fabaceae. In the classification system of Dahlgren the Fabales were in the superorder Fabiflorae (also called Fabanae) with three families corresponding to the subfamilies of Fabaceae in APG II. The other families treated in the Fabales by the APG II classification were placed in separate orders by Cronquist, the Polygalaceae within its own order, the Polygalales, and the Quillajaceae and Surianaceae within the Rosa ...

Senecio
''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. Variously circumscribed taxonomically, the genus ''Senecio'' is one of the largest genera of flowering plants. Description Morphology The flower heads are normally rayed with the heads borne in branched clusters, and usually completely yellow, but green, purple, white and blue flowers are known as well. In its current circumscription, the genus contains species that are annual or perennial herbs, shrubs, small trees, aquatics or climbers. The only species which are trees are the species formerly belonging to '' Robinsonia'' occurring on the Juan Fernández Islands. Chemistry Pyrrolizidine alkaloids are found in all ''Senecio'' species. These alkaloids serve as a natural biocides to deter or even kill animals that would eat them. Livestock generally do not find them palatable. ''Senecio'' species are used as food plants by the larvae of some Lepidoptera spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clematis
''Clematis'' is a genus of about 300 species within the buttercup family, Ranunculaceae. Their garden hybrids have been popular among gardeners, beginning with ''Clematis'' × ''jackmanii'', a garden standby since 1862; more hybrid cultivars are being produced constantly. They are mainly of Chinese and Japanese origin. Most species are known as clematis in English, while some are also known as traveller's joy, a name invented for the sole British native, ''C. vitalba'', by the herbalist John Gerard; virgin's bower for '' C. terniflora'', '' C. virginiana'', and '' C. viticella''; old man's beard, applied to several with prominent seedheads; leather flower for those with fleshy petals; or vase vine for the North American ''Clematis viorna''. Etymology The genus name ''Clematis'' is from Ancient Greek κληματίς : ''clēmatís,'' ("a climbing plant") from κλήμα : ''klḗma'' – 'twig, sprout, tendril'. Over 250 species and cultivars are known, often named for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clerodendrum
''Clerodendrum'' is a genus of flowering plants formerly placed in the family Verbenaceae, but now considered to belong to the Lamiaceae (mint) family. Its common names include glorybower, bagflower and bleeding-heart. It is currently classified in the subfamily Ajugoideae, being one of several genera transferred from Verbenaceae to Lamiaceae in the 1990s, based on phylogenetic analysis of morphological and molecular data. Estimates of the number of species in ''Clerodendrum'' vary widely, from about 150Yao-Wu Yuan, David J. Mabberley, Dorothy A. Steane, and Richard G. Olmstead. 2010.

Jacksonia Scoparia
''Jacksonia scoparia'', commonly known as dogwood (from its strong odour when burning), is a native species of a pea-flowered, greyish, leafless, broom-like shrub or small tree that occurs in the south east of Queensland, Australia and eastern New South Wales. Description ''Jacksonia scoparia'' grows as a shrub or small tree, reaching 12 m in height. Its grey bark is rough with furrows. Taxonomy Scottish botanist Robert Brown described the dogwood in 1811 in Rees's Cyclopædia, from material sent by John White and George Caley to Kew Garden. The genus name honours George Jackson and the species name is derived from the foliage, which resembles Scotch broom ('' Cytisus scoparius''). Jenny Chappill classified it in Group 4 within the genus, along with '' Jacksonia chappilliae'', '' Jacksonia rhadinoclona'' and '' Jacksonia stackhousei''—all from eastern Australia. Dogwood Creek in Queensland was named after the profusion of the plant in the area by explorer Ludwig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Crebra
''Eucalyptus crebra'', commonly known as the narrow-leaved ironbark, narrow-leaved red ironbark or simply ironbark, and as muggago in the indigenous Dharawal language, is a species of small to medium-sized tree endemic to eastern Australia. It has hard, rough "ironbark" from its trunk to small branches, linear to lance-shaped adult leaves, flower buds in groups of seven, nine or eleven, white flowers and cup-shaped, barrel-shaped or hemispherical fruit. A variable species, it grows in woodland and forest from the Cape York Peninsula to near Sydney. It is an important source of nectar in the honey industry and its hard, strong timber is used in construction. Description ''Eucalyptus crebra'' is a tree that typically grows to a height of and forms a lignotuber. It has persistent thick, rough, deeply furrowed, greyish black "ironbark" from the base of its trunk to the small branches.

Eucalyptus Tereticornis
''Eucalyptus tereticornis'', commonly known as forest red gum, blue gum or red irongum, is a species of tree that is native to eastern Australia and southern New Guinea. It has smooth bark, lance-shaped to curved adult leaves, flower buds in groups of seven, nine or eleven, white flowers and hemispherical fruit. Description ''Eucalyptus tereticornis'' is a tree that typically grows to a height of and forms a lignotuber. The trunk is straight, usually unbranched for more than half of the total height of the tree and has a girth of up to dbh. Thereafter, limbs are unusually steeply inclined for a ''Eucalyptus'' species. The bark is shed in irregular sheets, resulting in a smooth trunk surface coloured in patches of white, grey and blue, corresponding to areas that shed their bark at different times. Young plants and coppice regrowth have dull bluish green, egg-shaped leaves that are long and wide. Adult leaves are the same shade of green on both sides, lance-shaped to curved, ...

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 reco ...

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with syste ...
