Drosera Subtilis
''Drosera subtilis'' is an erect annual species in the carnivorous plant genus ''Drosera''. It is native to northern Western Australia and a single site in the Northern Territory. In Western Australia, it has been collected from Beverley Springs Station, Bigge Island, and the Mitchell Plateau area all in the vicinity of the Kimberley region. In the Northern Territory, it has been found near Little Nourlangie Rock. It grows over sandstone near seepage margins in skeletal sandstone sand and black humus mixed soils. ''D. subtilis'' is anchored to the soil by a system of thin, fleshy roots and it lacks a tuber. It produces small carnivorous leaves along erect, reddish stems that can be high.Lowrie, Allen. 1998. ''Carnivorous Plants of Australia'', Vol. 3. University of Western Australia Press: Nedlands, Western Australia. ''Drosera subtilis'' has white flowers with four petals on an inflorescence that can produce 50 or more individual flowers. Each flower has four white ...

Annual Plant
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. The length of growing seasons and period in which they take place vary according to geographical location, and may not correspond to the four traditional seasonal divisions of the year. With respect to the traditional seasons, annual plants are generally categorized into summer annuals and winter annuals. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual plant can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Style (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and slen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eudicots Of Western Australia
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.

Caryophyllales Of Australia
Caryophyllales ( ) is a diverse and heterogeneous order of flowering plants that includes the cacti, carnations, amaranths, ice plants, beets, and many carnivorous plants. Many members are succulent, having fleshy stems or leaves. The betalain pigments are unique in plants of this order and occur in all its families with the exception of Caryophyllaceae and Molluginaceae. Description The members of Caryophyllales include about 6% of eudicot species. This order is part of the core eudicots. Currently, the Caryophyllales contains 37 families, 749 genera, and 11,620 species The monophyly of the Caryophyllales has been supported by DNA sequences, cytochrome c sequence data and heritable characters such as anther wall development and vessel-elements with simple perforations. Circumscription As with all taxa, the circumscription of Caryophyllales has changed within various classification systems. All systems recognize a core of families with centrospermous ovules and seeds. More ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnivorous Plants Of Australia
''Carnivorous Plants of Australia'' is a three-volume work on carnivorous plants by Allen Lowrie. The three tomes were published in 1987, 1989, and 1998, by University of Western Australia Press. An entirely updated three-volume work by Lowrie was published by Redfern Natural History Productions in December 2013 as ''Carnivorous Plants of Australia Magnum Opus''.Lowrie, A. 2013. ''Carnivorous Plants of Australia Magnum Opus - Volume Three''. Redfern Natural History Productions, Poole. . Content The first volume deals exclusively with tuberous sundews (genus ''Drosera''). The second is devoted to pygmy sundews, but also includes three tuberous species described since the publication of the first volume, as well as two other sundews that do not fit elsewhere ('' D. glanduligera'' and '' D. hamiltonii''). The final volume includes the remaining sundews of Australia, together with native species of ''Aldrovanda'', ''Byblis'', ''Cephalotus'', ''Nepenthes'', and ''Utricular ...

Drosera Banksii
''Drosera banksii'', commonly known as Banks' sundew, is a small annual species in the carnivorous plant genus ''Drosera''. The reniform-shaped leaves are attached to petioles and arranged in a circular pattern ( rosette) around the stem. The 5 mm wide flowers are white.Lowrie, A. 1991A field trip to Darwin.'' Carnivorous Plant Newsletter'', 20(4): 114-123. It is native to northern Australia (Queensland, the Northern Territory, and Western Australia) and Southeast Asia (Papua New Guinea and Western New Guinea).

Drosera Subg
''Drosera'', which is commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. 2 volumes. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica.McPherson, S.R. 2008. ''Glistening Carnivores''. Redfern NaturalHistory Productions Ltd., Poole. Charles Darwin performed much of the early research into ''Drosera'', engaging in a long series of experiments with Drosera rotundifolia which were the first to confirm carnivory in plants. In an 1860 letter, Darwin wrote, “…at the present moment, I care more about ''Drosera'' than the origin of all the species in the world.” Both the botanical name (from the Greek δρόσος: ''drosos'' = "dew, dew ...

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'' ...
