Verticordia Sect. Tropica
''Verticordia'' sect. ''Tropica'' is one of six sections in the subgenus ''Eperephes''. It includes three species of plants in the genus ''Verticordia''. Plants in this section occur are the only verticordias to occur in tropical areas of Western Australia and the Northern Territory, including the Kimberley and Kakadu National Park and they have the ability to regrow from a lignotuber after fire. (One species, '' V. decussata'', is endemic to the Northern Territory.) They have leaves which vary in size from tiny and pressed against the stem to long and curved but are always linear in shape. The flowers have fringed petals and lobed sepals with small, ear-like appendages and the style has a narrow band of hairs near its tip. When Alex George reviewed the genus in 1991, he described the section and gave it the name ''Tropica''. The name ''Tropica'' is a Latin word meaning "solstice" referring to the tropical distribution of these species. The type species for this section is ''Ve ...

Lignotuber
A lignotuber is a woody swelling of the root crown possessed by some plants as a protection against destruction of the plant stem, such as by fire. Other woody plants may develop basal burls as a similar survival strategy, often as a response to coppicing or other environmental stressors. However, lignotubers are specifically part of the normal course of development of the plants that possess them, and often develop early on in growth. The crown contains buds from which new stems may sprout, as well as stores of starch that can support a period of growth in the absence of photosynthesis. The term "lignotuber" was coined in 1924 by Australian botanist Leslie R. Kerr. Plants possessing lignotubers include many species in Australia: ''Eucalyptus marginata'' (Jarrah), ''Eucalyptus brevifolia'' (snappy gum) and ''Eucalyptus ficifolia'' (scarlet gum) all of which can have lignotubers wide and deep, as well as most mallees (where it is also known as a mallee root) and many ''Banksia ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Alex George (botanist)
Alexander Segger George (born 4 April 1939) is a Western Australian botanist. He is the authority on the plant genera ''Banksia'' and ''Dryandra''. The "bizarre" Restionaceae genus '' Alexgeorgea'' was named in his honour in 1976. Early life Alex Segger George was born in Western Australia on 4 April 1939. Career George joined the Western Australian Herbarium as a laboratory assistant at the age of twenty in 1959. He worked under Charles Gardner for a year before the latter's retirement, and partly credits him with rekindling an interest in banksias. In 1963 he graduated with a Bachelor of Arts from the University of Western Australia, and the following year added a botany major. Continuing at the Western Australian Herbarium as a botanist, in 1968 he was seconded as Australian Botanical Liaison Officer at the Royal Botanic Gardens in London. George also has an interest in history, especially historical biography of naturalists in Western Australia. He has published a number ...

Stigma (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 sle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appendage
An appendage (or outgrowth) is an external body part, or natural prolongation, that protrudes from an organism's body. In arthropods, an appendage refers to any of the homologous body parts that may extend from a body segment, including antennae, mouthparts (including mandibles, maxillae and maxillipeds), gills, locomotor legs ( pereiopods for walking, and pleopods for swimming), sexual organs (gonopods), and parts of the tail (uropods). Typically, each body segment carries one pair of appendages. An appendage which is modified to assist in feeding is known as a maxilliped or gnathopod. In vertebrates, an appendage can refer to a locomotor part such as a tail, fins on a fish, limbs (legs, flippers or wings) on a tetrapod; exposed sex organ; defensive parts such as horns and antlers; or sensory organs such as auricles, proboscis ( trunk and snout) and barbels. Appendages may become ''uniramous'', as in insects and centipedes, where each appendage comprises a single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sepal
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 ...

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 ...

Kakadu National Park
Kakadu National Park is a protected area in the Northern Territory of Australia, southeast of Darwin. It is a World Heritage Site. Kakadu is also gazetted as a locality, covering the same area as the national park, with 313 people recorded living there in the 2016 Australian census. Water buffalo, which are now an environmental pest, were released in the area in the late 19th century, and missionaries established a mission at Oenpelli (present-day Gunbalanya) in 1925. A few pastoralists, crocodile hunters and wood cutters made a living at various times during the 20th century. The area was given protected status bit by bit from the 1970s onwards. The park is located within the Alligator Rivers Region of the Northern Territory. It covers an area of , extending nearly from north to south and over from east to west. It is roughly the size of Wales or one-third the size of Tasmania, and is the second largest national park in Australia (after the Munga-Thirri–Simpson Dese ...
