Capillipedium Spicigerum
''Capillipedium spicigerum'', commonly known as scented-top grass, is a species of perennial grass in the family Poaceae that is native to Australia. Description ''Capillipedium spicigerum'' is a tufted perennial bunchgrass, without stolons or rhizomes. The culms, or stems of the grass grow to in height and have hairy nodes. The lower leaf sheaths of the plant are silky hairy. The leaf blades are long and wide at the base. The inflorescence of the plant, or the collections of flowers, are a purplish open panicle, long with short racemes on slender branches. The flowers emit a scent when crushed. The racemes have 3 to 8 pairs of spikelets, one stalked the other unstalked. Flowering is late spring to autumn. A close relative to ''Capillipedium spicigerum'' seems to be C. mistryi' A. P. Tiwari Landgefrom India. For more details refer to Taxonomy ''Capillipedium spicigerum'' was described by S.T. Blake in 1944. Habitat and ecology ''Capillipedium spicigerum'' is found ...

Perennial
In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of the local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a peren ...

Raceme
A raceme () or racemoid is an unbranched, indeterminate growth, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica''), radish (genus ''Raphanus''), and orchid (genus ''Phalaenopsis'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate growth, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''Pedicel (botany), pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poales Of Australia
The Poales are a large order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, rushes and sedges. 14 plant families are currently recognized by botanists to be part of Poales. Description The flowers are typically small, enclosed by bracts, and arranged in inflorescences (except in three species of the genus '' Mayaca'', which possess very reduced, one-flowered inflorescences). The flowers of many species are wind pollinated; the seeds usually contain starch. Taxonomy The APG IV system (2016) accepts the order within a monocot clade called commelinids, with 14 families.Huijun Wang, Zhigang Wu, Tao Li, Jindong Zhao, Phylogenomics resolves the backbone of Poales and identifies signals of hybridization and polyploidy, ''Molecular Phylogenetics and Evolution'', Volume 200, 2024, 108184, ISSN 1055-7903, https://doi.org/10.1016/j.ympev.2024.108184.

Endemic Flora Of Australia
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Bunchgrasses Of Australasia
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any habitat ...

Australian Plant Name Index
The Australian Plant Name Index (APNI) is an online database of all published names of Australian vascular plants. It covers all names, whether current names, synonyms or invalid names. It includes bibliographic and typification details, information from the Australian Plant Census including distribution by state, links to other resources such as specimen collection maps and plant photographs, and the facility for notes and comments on other aspects. History Originally the brainchild of Nancy Tyson Burbidge, it began as a four-volume printed work consisting of 3,055 pages and containing over 60,000 plant names. Compiled by Arthur Chapman, it was part of the Australian Biological Resources Study (ABRS). In 1991 it was made available as an online database and handed over to the Australian National Botanic Gardens. Two years later, responsibility for its maintenance was given to the newly formed Centre for Plant Biodiversity Research. Scope Recognised by Australian herbaria as th ...

Stanley Thatcher Blake
Stanley Thatcher Blake (1910 – 24 February 1973) was an Australian botanist who served as president of the Royal Society of Queensland and who was associated with the Queensland Herbarium beginning in 1945 until his death. Background Prior to his stint with the Herbarium, Blake received a Walter and Eliza Hall Fellowship which allowed him to undertake botanical collecting expeditions to Western Queensland (1935–1937). Blake is also credited with validating the name ''Melaleuca quinquenervia'', which was initially proposed by Antonio José Cavanilles (1745–1804).

Spikelet
A spikelet, in botany, describes the typical arrangement of the inflorescences of grasses, sedges and some other monocots. Each spikelet has one or more florets. The spikelets are further grouped into panicles or spikes. The part of the spikelet that bears the florets is called the rachilla. In grasses In Poaceae, the grass family, a spikelet consists of two (or sometimes fewer) bracts at the base, called glumes, followed by one or more florets. A floret consists of the flower surrounded by two bracts, one external (the lemma) and one internal (the palea). The perianth is reduced to two scales, called lodicules, that expand and contract to spread the lemma and palea; these are generally interpreted to be modified sepals. The flowers are usually hermaphroditic — maize being an important exception — and mainly anemophilous or wind-pollinated, although insects occasionally play a role. Lemma Lemma is a phytomorphological term referring to a part of the spikelet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panicle
In botany, 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'' co ...
