Caladenia Lateritica
''Caladenia lateritica'', also known as white primrose orchid, is a plant in the orchid family Orchidaceae and is endemic to relatively inaccessible, high lateritic plateaux in a high rainfall area in south-western Western Australia. It is a ground orchid with a single hairy leaf and one or two white flowers on a thin, sparsely-hairy stem. It is similar to '' Caladenia flava'' but is distinguished by its fragrant white versus yellow flowers with prominent red stripes and spots on the dorsal sepal and lateral petals. ''Caladenia lateritica'' mimics '' Conostylis setosa'' (Haemodoraceae) in terms of flowering time, height, colour and fragrance. It also shares a native bee pollinator with ''Conostylis setosa'', which provides pollen and nectar whereas the orchid is rewardless. Description ''Caladenia lateritica'' is a terrestrial, perennial, deciduous, herb with spheroid, annually replaced tubers situated 8–15 cm below the soil surface and forming a single, hairy, linear leaf, s ...

Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Caladenia Rosea
''Caladenia rosea'' is a plant in the orchid family Orchidaceae and is endemic to relatively inaccessible, high lateritic plateaux in a high rainfall area in south-western Western Australia. It is a terrestrial orchid with a single hairy leaf and up to three pink flowers on a thin, sparsely-hairy stem. It is similar to ''Caladenia flava'' but is distinguished by the perianth being pink to dark pink with prominent red striping and spotting on the dorsal sepal and lateral petals. ''Caladenia rosea'' mimics ''Hypocalymma robustum'' (Myrtaceae) in terms of flowering time, colour and scent. Description ''Caladenia rosea'' is a terrestrial, perennial, deciduous, herb with spheroid, annually replaced tubers situated 8–15 cm below the soil surface and forming a single, hairy, linear leaf, tinged purple and usually with darker purple veining below, long and wide. There are up to three flowers borne on a slender, fine, sparsely silky-hairy raceme, tall, with a bract in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grove (nature)
A grove is a small group of trees with minimal or no undergrowth, such as a sequoia grove, or a small orchard planted for the cultivation of fruits or nuts. Other words for groups of trees include ''woodland'', ''woodlot'', ''thicket'', and ''stand''. The main meaning of " grove" is a group of trees that grow close together, generally without many bushes or other plants underneath. It is an old word in the English language, with records of its use dating as far back as the late 9th century. The word's true origins are unknown; the word, or a related root, cannot be found in any other Germanic language. Naturally-occurring groves are typically small, perhaps a few acres at most.In contrast, orchards, which are normally intentional planting of trees, may be small or very large, like the apple orchards in Washington state, and orange groves in Florida. Historically, groves were considered sacred in pagan, pre-Christian Germanic and Celtic cultures. Helen F. Leslie-Jacobsen a ...

Dr Maarten Joost Maria Christenhusz (born 27 April 1976) is a Dutch botanist, natural historian and photographer. Career He was born in Enschede, the Netherlands, received his undergraduate and master's degrees from Utrecht University in Biology, and earned his PhD from the University of Turku, Finland in 2007. He is an authority on fern, gymnosperm and angiosperm classification, and is a contributor to the Angiosperm Phylogeny Group (compiler of APG IV). He has specialised in Marattiaceae and he described many species of ''Danaea'', including ''Danaea kalevala'' from the Lesser Antilles. A species of Moraceae, ''Dorstenia christenhuszii'' was named in honour of its discoverer. He is editor for the Linnean Society. He lives in Kingston-upon-Thames, Surrey, UK.

Kingsley Dixon
Kingsley Wayne Dixon (Ph.D.) is an Australian botanist currently working as a professor at Curtin University. He was the founding Director of Science at Kings Park and Botanic Gardens, and helped to establish the laboratories there as among the world's leading. Early life Dixon grew up in the Perth suburb of Morley, Western Australia. He would spend his time exploring the bushland that existed in the suburb during his childhood, which encouraged his interest in botany. Career Dixon received a Bachelor of Science (Hons) and a PhD from the University of Western Australia (UWA). Dixon was the founding Director of Science at Kings Park and Botanic Gardens from 1982 to 2014. Before working as a professor at Curtin University, he was a professor at UWA. One of Dixon's most notable achievements is the 1992 discovery of smoke as a cause for the germination of Australian plants after bushfires. He later helped to show that plant species in other parts of the world also have germinat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labellum (botany)
In botany, the labellum (or lip) is the part of the flower of an orchid or '' Canna'', or other less-known genera, that serves to attract insects, which pollinate the flower, and acts as a landing platform for them. ''Labellum'' (plural: ''labella'') is the Latin diminutive of ''labrum'', meaning lip. The labellum is a modified petal and can be distinguished from the other petals and from the sepals by its large size and its often irregular shape. It is not unusual for the other two petals of an orchid flower to look like the sepals, so that the labellum stands out as distinct. Bailey, L. H. ''Gentes Herbarum: Canna x orchiodes''. (Ithaca), 1 (3): 120 (1923); Khoshoo, T. N. & Guha, I. ''Origin and Evolution of Cultivated Cannas.'' Vikas Publishing House. In orchids, the labellum is the modified median petal that sits opposite from the fertile anther and usually highly modified from the other perianth segments. It is often united with the column and can be hinged or movable, fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...
