Matricaria
''Matricaria'' is a genus of flowering plants in the chamomile tribe within the sunflower family. Some of the species have the common name of "mayweed," but this name also refers to plants not in this genus. Most are very common in the temperate regions of Europe, Asia, and America, as well as in northern and southern Africa, and some are naturalised in Australia. ''Matricaria occidentalis'' is native to North America; other species have been introduced there. These are hardy, pleasantly aromatic annuals, growing along roadsides in ruderal communities and in fallow land rich in nutrients. Though many are considered nuisance weeds, they are suitable for rock gardens and herb gardens, and as border plants. Their many-branched stems are prostrate to erect, glabrous, and very leafy. Their bipinnate leaves have numerous linear, narrowly lobed leaflets. The flowers are radially symmetrical. The greenish-yellow capitula are semi-spherical. The white ray florets can be present ...

Lime-speck Pug
The lime-speck pug (''Eupithecia centaureata'') is a moth of the family Geometridae. It is a common species throughout the Palearctic region (where it is found in Europe, Central Asia, Mongolia, southern Siberia, eastern China (Guangdong) and Taiwan), the Near East and North Africa. Description This is a distinctive species, all the wings being largely white except for a black blotch on the costa of the forewing. The wingspan is 20–24 mm. In the ab. ''obscura'' Dietze.(perhaps developed chiefly in Asia but also recorded from the Tyrol) the ground-colour of both wings has a smoky suffusion. In the ab. ''centralisata'' Stgr., chiefly from Palestine and Central Asia, the markings are weaker, sometimes (except the discal mark) almost entirely obsolete.Prout, L. B. (1912–16). Geometridae. In A.

Anthemideae
Anthemideae is a tribe of flowering plants in the family, Asteraceae, and the subfamily Asteroideae. They are distributed worldwide with concentrations in central Asia, the Mediterranean Basin, and southern Africa.Oberprieler, C., et al. (2007) A new subtribal classification of the tribe Anthemideae (Compositae). ''Willdenowia'' 37(1): 89–114. Most species of plant known as chamomile belong to genera of this tribe. As of 2006 there were about 1800 species classified in 111 genera. In 2007 the tribe was divided into 14 subtribes, including Glebionidinae, the source of hybrid garden marguerites. Genera Anthemideae genera recognized by the Global Compositae Database as March 2022: *'' × Anthematricaria'' *'' × Anthemimatricaria'' *''Aaronsohnia'' *''Achillea'' *''Adenanthellum'' *''Adenoglossa'' *''Ajania'' *''Ajaniopsis'' *''Allardia'' *''Anacyclus'' *''Anthemis'' *'' Arctanthemum'' *''Argyranthemum'' *''Artemisia'' *'' Artemisiella'' *''Athanasia'' *'' Belli ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Head (botany)
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorp ...

Bipinnate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...
