Hoya Aldrichii
''Hoya aldrichii'', commonly known as the Christmas Island waxvine, is a species of flowering plant in the Apocynaceae or dogbane family. It is a vine that is endemic to Christmas Island, an Australian territory in the north-eastern Indian Ocean, where it is a common epiphyte in the shrublands of the island's coastal terraces. The specific epithet honours Captain Aldrich, commander of the survey vessel HMS ''Egeria'', which visited Christmas Island in 1887.Flora of Australia Online. Description ''Hoya aldrichii'' is a tall climber. Its stems are glabrous with pale bark. The leaves are elliptical, rounded at the base, entire, acuminate or acute and glabrous; they are 75–150 mm long, 35–60 mm wide, with a 10–15 mm long petiole. The flowers occur in umbel In botany, an umbel is an inflorescence that consists of a number of short flower stalks (called pedicels) that spread from a common point, somewhat like umbrella ribs.

William Hemsley (botanist)
William Botting Hemsley (29 December 1843, in East Hoathly – 7 October 1924, in Kent) was an English botanist and 1909 Victoria Medal of Honour recipient. He was born in East Hoathly, Sussex and in 1860 started work at the Royal Botanic Gardens, Kew as an Improver, then Assistant for India in the Herbarium, finally Keeper of Herbarium and Library. He wrote a number of botanical works. In 1888, a genus of flowering plants from south-east Asia, belonging to the family Cucurbitaceae was named '' Hemsleya'' in his honour. He was elected a Fellow of the Royal Society Fellowship of the Royal Society (FRS, ForMemRS and HonFRS) is an award granted by the judges of the Royal Society of London to individuals who have made a "substantial contribution to the improvement of natural knowledge, including mathemat ... in June 1889.

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 ...

Vines
A vine (Latin ''vīnea'' "grapevine", "vineyard", from ''vīnum'' "wine") is any plant with a growth habit of trailing or scandent (that is, climbing) stems, lianas or runners. The word ''vine'' can also refer to such stems or runners themselves, for instance, when used in wicker work.Jackson; Benjamin; Daydon (1928). ''A Glossary of Botanic Terms with their Derivation and Accent'', 4th ed. London: Gerald Duckworth & Co. In parts of the world, including the British Isles, the term "vine" usually applies exclusively to grapevines (''Vitis''), while the term "climber" is used for all climbing plants. Growth forms Certain plants always grow as vines, while a few grow as vines only part of the time. For instance, poison ivy and bittersweet can grow as low shrubs when support is not available, but will become vines when support is available. A vine displays a growth form based on very long stems. This has two purposes. A vine may use rock exposures, other plants, or other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Christmas Island
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gentianales Of Australia
Gentianales is an order of flowering plants, included within the asterid clade of eudicots. It comprises more than 20,000 species in about 1,200 genera in 5 families. More than 80% of the species in this order belong to the family Rubiaceae. Many of these flowering plants are used in traditional medicine. They have been used to treat pain, anxiety, cancers and neurological conditions. Taxonomy In the classification system of Dahlgren the Gentiales were in the superorder Gentianiflorae (also called Gentiananae). The following families are included according to the APG III system: * Family Apocynaceae (424 genera) * Family Gelsemiaceae (2 genera) * Family Gentianaceae (87 genera) * Family Loganiaceae (13 genera) * Family Rubiaceae (611 genera) Phylogeny The following phylogenetic tree is based on molecular phylogenetic studies of DNA sequences. Etymology It takes its name from the family Gentianaceae, which in turn is based on the name of the type genus, ''Gentiana''. Th ...

Australian Biological Resources Study
Australian Biological Resources Study (ABRS) is a project undertaken by Parks Australia Division of Australia's Department of the Environment, Water, Heritage and the Arts (DEWHA). Background ABRS was founded in 1973 from the recommendations of a 1972 Senate Select Committee report on Wildlife Conservation. Its purpose is to collate from the many libraries, museums and other collections the taxonomy of Australia's estimated 2 million species of flora and fauna, including aquatic species. These represent almost 20% of the earth's biodiversity, 80% of which are unique to Australia. ABRS has undertaken active funding for taxonomic research of Australia's biodiversity and is internationally recognised for its extensive data bases and publications. Publications The most important outputs of the ABRS has been the publication of the multi-volume ''Flora of Australia'' and '' Fauna of Australia'' series. Other output includes ''The Banksia Atlas'' and the "Platypus" database pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hoya Cinnamomifolia
''Hoya cinnamomifolia'' is a vine that comes from the island of Java Java (; id, Jawa, ; jv, ꦗꦮ; su, ) is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 151.6 million people, Java is the world's List .... It is one of the larger members of the Hoya genus with typically one leaf per node. Each leaf is large, dark green, and has lighter colored veins that run parallel to the leaf. The leaves can get as big as 15 cm by 6 cm. Hoya cinnamomifolia got its name due to the resemblance of its leaves to those of Cinnamomum verum. The flowers produced come in umbels of 20-30 and have a lime green corolla and bright burgundy corona. The corolla of each flower appears bent backwards and the corona protrudes out but has a flat surface. On the flowers is produced a sugary nectar and the flowers are rather short lived. Each flower is 2 cm in diameter. Ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbel
In botany, an umbel is an inflorescence that consists of a number of short flower stalks (called pedicels) that spread from a common point, somewhat like umbrella ribs. The word was coined in botanical usage in the 1590s, from Latin ''umbella'' "parasol, sunshade". The arrangement can vary from being flat-topped to almost spherical. Umbels can be simple or compound. The secondary umbels of compound umbels are known as umbellules or umbellets. A small umbel is called an umbellule. The arrangement of the inflorescence in umbels is referred to as umbellate, or occasionally subumbellate (almost umbellate). Umbels are a characteristic of plants such as carrot, parsley, dill, and fennel in the family Apiaceae; ivy, ''Aralia'' and ''Fatsia'' in the family Araliaceae; and onion (''Allium'') in the family Alliaceae. An umbel is a type of indeterminate inflorescence. A compressed cyme, which is a determinate inflorescence, is called umbelliform if it resembles an umbel. Gallery File ...

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), ...
