Alternanthera Bettzickiana
''Alternanthera bettzickiana'', commonly known as calico-plant, is a species of flowering plant in the family Amaranthaceae. It is commonly used as an ornamental edging plant. Native to South America, its cultivar 'Red' is similar in appearance to some of the '' Alternanthera dentata'' and '' Alternanthera brasiliana'' varieties. Description This perennial herb is between 20 and 50 cm tall and has variegated leaves. Its branched stems have a circular section towards the base and quadrangular towards the summit. They present some hairs at the nodes and the apex, as well as at the level of the short petioles (1 to 4 mm long). The leaf blade is 1 to 6 mm long and 0.5 to 2 mm wide. It is green, red or green tinged with red or yellow. Its shape is oval, sometimes a little oblong or spatulate.

Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, ''Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

Flora Of Southern America
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is '' fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms '' gut flora'' or '' skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a communi ...

Plants Described In 1865
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperm ...

Australian Government
The Australian Government, also known as the Commonwealth Government or simply as the federal government, is the national executive government of Australia, a federal parliamentary constitutional monarchy. The executive consists of the prime minister, cabinet ministers and other ministers that currently have the support of a majority of the members of the House of Representatives (the lower house) and also includes the departments and other executive bodies that ministers oversee. The current executive government consists of Anthony Albanese and other ministers of the Australian Labor Party (ALP), in office since the 2022 federal election. The prime minister is the head of the federal government and is a role which exists by constitutional convention, rather than by law. They are appointed to the role by the governor-general (the federal representative of the monarch of Australia). The governor-general normally appoints the parliamentary leader who commands the ...

Australian Tropical Rainforest Plants
Australian Tropical Rainforest Plants, also known as RFK, is an identification key giving details—including images, taxonomy, descriptions, range, habitat, and other information—of almost all species of flowering plants (i.e. trees, shrubs, vines, forbs, grasses and sedges, epiphytes, palms and pandans) found in tropical rainforests of Australia, with the exception of most orchids which are treated in a separate key called Australian Tropical Rainforest Orchids (see External links section). A key for ferns is under development. RFK is a project initiated by the Australian botanist Bernie Hyland. History The information system had its beginnings when Hyland started working for the Queensland Department of Forestry in the 1960s. It was during this time that he was tasked with the creation of an identification system for rainforest trees, but given no direction as to its format. Having little belief in single-access keys, he began work on creating a multi-access key (o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ovary
The ovary () is a gonad in the female reproductive system that produces ova; when released, an ovum travels through the fallopian tube/ oviduct into the uterus. There is an ovary on the left and the right side of the body. The ovaries are endocrine glands, secreting various hormones that play a role in the menstrual cycle and fertility. The ovary progresses through many stages beginning in the prenatal period through menopause. Structure Each ovary is whitish in color and located alongside the lateral wall of the uterus in a region called the ovarian fossa. The ovarian fossa is the region that is bounded by the external iliac artery and in front of the ureter and the internal iliac artery. This area is about 4 cm x 3 cm x 2 cm in size.Daftary, Shirish; Chakravarti, Sudip (2011). Manual of Obstetrics, 3rd Edition. Elsevier. pp. 1-16. . The ovaries are surrounded by a capsule, and have an outer cortex and an inner medulla. The capsule is of dense connect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anther
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs 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 (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the Connective (botany), 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 size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''. The stamens in a flower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calyx (botany)
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 Etymology 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'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin. Description The term '' tepal'' is usually applied when the parts of the perianth are difficult to distinguish, e.g. the petal ...
