Calectasia
''Calectasia'' is a genus of about fifteen species of flowering plants in the family Dasypogonaceae and is endemic to south-western Australia. Plants is this genus are small, erect shrubs with branched stems covered by leaf sheaths. The flowers are star-shaped, lilac-blue to purple and arranged singly on the ends of short branchlets. Description Plants in the genus ''Calectasia'' are small, often rhizome-forming shrubs with erect, branched stems with sessile leaves arranged alternately along the stems, long and about wide, the base held closely against the stem and the tip pointed. The flowers are arranged singly on the ends of branchlets and are bisexual, the three sepals and three petals are similar to each other, and joined at the base forming a short tube but spreading, forming a star-like pattern with a metallic sheen. Six bright yellow or orange stamens form a tube in the centre of the flower with a thin style extending beyond the centre of the tube. Taxonomy The genus ...

Dasypogonaceae
Dasypogonaceae is a family of flowering plants, one that has not been commonly recognized by taxonomists; the plants it contains were usually included in the family Xanthorrhoeaceae. If valid, Dasypogonaceae includes four genera with 16 species. The 2016 APG IV system places the family in the order Arecales, after several studies revealed the family as a sister-family to Arecaceae. The earlier APG III (2009), APG II (2003), and the 1998 APG system all accepted the validity of the family, assigning it to the clade commelinids, but leaving it unplaced as to order. The commelinids are monocots, the broad group to which, in any event, these plant clearly belong. The family is endemic to Australia, and comprises 16 species in four genera. The best known representative is ''Kingia australis ''Kingia'' is a genus consisting of a single species, ''Kingia australis'', and belongs to the plant family Dasypogonaceae. The Aboriginal name bullanock is used as a common name for the plant. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Reproductive Morphology
Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants (green algae, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it was understood that the pollination process involved ...

Mimicry In Plants
In evolutionary biology, mimicry in plants is where a plant organism evolves to resemble another organism physically or chemically, increasing the mimic's Darwinian fitness. Mimicry in plants has been studied far less than mimicry in animals, with fewer documented cases and peer-reviewed studies. However, it may provide protection against herbivory, or may deceptively encourage mutualists, like pollinators, to provide a service without offering a reward in return. Types of plant mimicry include Bakerian, where female flowers imitate males of the same species, Müllerian mimicry of the flower or fruit, where a plant mimics a rewarding flower (Dodsonian), luring pollinators by mimicking another species of flower, or fruit where feeders of the other species are attracted to a fake fruit to distribute seeds, Vavilovian, where a weed is unintentionally artificially selected to resemble a crop plant, Pouyannian, in which a flower imitates a female mate for a pollinating insect, Batesi ...

Endemic
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
