Leionema Praetermissum
''Leionema praetermissum'', is a shrub with warty stems covered in hairs, white flowers with spreading petals, and prominent stamens. It has a restricted distribution in New South Wales. Description ''Leionema praetermissum'' is a shrub to high with several or few stems emanating from the base. The stems are warty and needle-shaped with occasional white star-shaped hairs. The leaves are smooth, narrow, linear to lance shaped, long, edges slightly rolled under, arranged alternately, sometimes crowded, smooth and sessile or on a short petiole long, and ending with a sharp point. The inflorescence is a cluster of 3-10 flowers at the end of branches or in the leaf axils on a pedicel long, flowers barely longer than the leaves. The peduncle is slender and warty, the pedicels long. The triangular, narrow calyx lobes are smooth on the outside with a stiff apex. The 5 petals are spreading, each petal long, upperside white, underneath pale green, glandular and there are 10 promin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phillipa Alvarez
Philippa is a feminine given name meaning "lover of horses" or " horses' friend". Common alternative spellings include ''Filippa'' and ''Phillipa''. Less common is ''Filipa'' and even ''Philippe'' (cf. the French spelling of '' Philippa of Guelders'': ''Philippe de Gueldres''). It is the feminine form of the masculine name ''Philip''. It is composed of the Greek elements ''philein'' (to love) and ''hippos'' (horse), and is derived from the name of Alexander the Great's father, the ancient Greek king, '' Philip II of Macedon'' (''aka'' ''Philippos'', ''Filippos'', and ''Pilipos''), who was an avid horse lover.

Sessility (botany)
In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts (such as flowers and leaves) that have no stalk. Plant parts can also be described as subsessile, that is, not completely sessile. A sessile flower is one that lacks a pedicel (flower stalk). A flower that is not sessile is pedicellate. For example, the genus ''Trillium'' is partitioned into two subgenera, the sessile-flowered trilliums (''Trillium'' subg. ''Sessilium'') and the pedicellate-flowered trilliums. Sessile leaves lack petioles (leaf stalks). A leaf that is not sessile is petiolate. For example, the leaves of most monocotyledons lack petioles. The term sessility is also used in mycology to describe a fungal fruit body that is attached to or seated directly on the surface of the substrate, lacking a supporting stipe or pedicel Pedicle or pedicel may refer to: Human anatomy *Pedicle of vertebral arch, the segment between the transvers ...

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses (Poaceae), ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts. In cultivation In Halloween types of pumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a "jack-o'-lantern".

Peduncle (botany)
In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphylls) at nodes. The main axis of an inflorescence above the peduncle is the rachis. There are no flowers on the peduncle but there are flowers on the rachis. When a peduncle arises from the ground level, either from a compressed aerial stem or from a subterranean stem (rhizome, tuber, bulb, corm), with few or no bracts except the part near the rachis or receptacle, it is referred to as a scape. The acorns of the pedunculate oak are borne on a long peduncle, hence the name of the tree. See also *Pedicel (botany) *Scape (botany) In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle. Typically it takes the form of a long, leafles ... Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calyx (botany)
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Specific Epithet
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colo River
The Colo River, a perennial stream that is part of the Hawkesbury-Nepean catchment, is located in the Central Tablelands of New South Wales, Australia. Course The Colo River rises on the Great Dividing Range, northeast of Newnes, formed by the confluence of the Wolgan River and the Capertee River, which respectively drain the Wolgan and Capertee Valleys north of Lithgow. Colo River flows eastwards and then south through a deep gorge in the northern section of the Blue Mountains. The majority of the river lies in Wollemi National Park. The middle Colo is inaccessible, rugged and remote. The wilderness was saved from development, logging and damming in the late 1970s by the Colo Wilderness Preservation Society and other environmentalists. Emerging from the wilderness region, the lower part of the Colo River flows through a scenic, narrow agricultural valley and reaches the Hawkesbury River at Lower Portland north of Windsor. Tributaries of the Colo include the Wollangambe Riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wollemi National Park
The Wollemi National Park () is a protected national park and wilderness area that is located in the northern Blue Mountains and Lower Hunter regions of New South Wales, in eastern Australia. The park, the second largest national park in New South Wales, contains the Wollemi Wildernessthe largest such wilderness area in Australiaand is situated approximately northwest of Sydney. The Wollemi National Park is one of the eight protected areas that, in 2000, was inscribed to form part of the UNESCO World Heritagelisted Greater Blue Mountains Area. The Wollemi National Park is the most northwesterly of the eight protected areas within the World Heritage Site. The national park forms part of the Great Dividing Range. The only known living wild specimens of the Wollemi Pine (''Wollemia nobilis'') were discovered in 1994. Special efforts were made to protect the trees when the 2019-20 Australian bushfires burned through the park. The national park is bounded to the north by the Go ...
