Omphalodes Verna
''Omphalodes verna'', the creeping navelwort or blue-eyed-Mary, is a rhizomatous herbaceous perennial plant in the genus ''Omphalodes'' belonging to the family Boraginaceae. Etymology The genus name ''Omphalodes'' derives from the Greek word , meaning navel, referring to the shape of the small fruits, while the name ''verna'' of the species, deriving from the Latin , refers to the early blooming flowers. Description ''Omphalodes verna'' can reach in height. The stem snakes across the ground (hence the alternative name of creeping forget-me-not). The overwintering buds are situated just below the soil surface ( hemicryptophyte). This species can spread quickly, it is hard to uproot and by some accounts may even be invasive, but mostly coexists with other plants well. Its leaves are grooved, semi-evergreen and medium green, about long and wide. They are veiny, with fine hairs and oval to heart in shape, and pointed at the tip. In Spring the plant produces clusters of 3-5 p ...

Omphalodes
''Omphalodes'' (navelwort) is a genus of flowering plants in the family Boraginaceae, widely distributed in the temperate Northern Hemisphere. In spring they produce blue or white flowers similar to forget-me-nots. Both the Greek ''Omphalodes'' (navel-like) and the English "navelwort" refer to the shape of the seeds. '' O. verna'' and cultivars of '' O. cappadocica'' are grown in gardens for their blue flowers which in spring appear above the leaves in loose sprays. They are woodland plants, preferring some shade. Systematics The genus ''Omphalodes'' traditionally contained many species that have been split-off in 2014 and 2016 The Japanese "''Omphalodes''" and "''Omphalodes scorpioides''" turned out not to be closely related to ''Omphalodes'', and were separated as distinct genera, ''Nihon'' and '' Memoremea'' respectively. Serrano et al. separated the Iberian annual species as '' Iberodes''. This left the remainder of species from Western Eurasia as sister to New World speci ...

Conrad Moench
Conrad Moench (sometimes written Konrad Mönch; 15 August 1744 – 6 January 1805) was a German botanist, professor of botany at Marburg University from 1786 until his death. He wrote 'Methodus Plantas horti botanici et agri Marburgensis' in 1794, an arranged account of plants in the fields and gardens of Marburg. In 1802 he named the plant '' Gillenia trifoliata'' in a supplement to a local flora of the city of Marburg. He also named the plant genus ''Echinacea'' (1794). The botanical genus '' Moenchia'' (family Caryophyllaceae Caryophyllaceae, commonly called the pink family or carnation family, is a family of flowering plants. It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactacea ...) is named in his honor. The standard botanical author abbreviation Moench is applied to plants he described. Principal writings * ''Enumeratio plantarum indigenarum Hassiae praesertim inferioris, ...

Rhizome
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied ...

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent wood, woody stems above ground. This broad category of plants includes many perennial plant, perennials, and nearly all Annual plant, annuals and Biennial plant, biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. Glossary of botanical terms#scarious, scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentatio ...

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opin ...

Boraginaceae - Omphalodes Verna-1
Boraginaceae, the borage or forget-me-not family, includes about 2,000 species of shrubs, trees and herbs in 146, to 156 genera with a worldwide distribution. The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. Under the older Cronquist system it was included in Lamiales, but it is now clear that it is no more similar to the other families in this order than they are to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae in eleven distinct families: Boraginaceae ''sensu stricto'', Codonaceae, Coldeniaceae, Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have pet ...

Raunkiær Plant Life-form
The Raunkiær system is a system for categorizing plants using life-form categories, devised by Danish botanist Christen C. Raunkiær and later extended by various authors. History It was first proposed in a talk to the ''Danish Botanical Society'' in 1904 as can be inferred from the printed discussion of that talk, but not the talk itself, nor its title. The journal, Botanisk Tidsskrift, published brief comments on the talk by M.P. Porsild, with replies by Raunkiær. A fuller account appeared in French the following year. Raunkiær elaborated further on the system and published this in Danish in 1907.Ch. 2 in Raunkiær (1934): The life-forms of plants and their bearings on geography, p. 2-104. The original note and the 1907 paper were much later translated to English and published with Raunkiær's collected works.Ch. 1 in Raunkiær (1934): Biological types with reference to the adaption of plants to survive the unfavourable season, p. 1. Modernization Raunkiær's life-form ...

Hermaphrodite
In reproductive biology, a hermaphrodite () is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes. Many taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. For example, the great majority of tunicates, pulmonate molluscs, opisthobranch, earthworms, and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Animal species having different sexes, male and female, are called gonochoric, which is the opposite of hermaphrodite. There are also species where hermaphrodites exist alongside males (called androdioecy) or alongside females (called gynodioecy), or all three exist in the same species (called trioecy); these three syst ...

Forget-me-not
''Myosotis'' ( ) is a genus of flowering plants in the family Boraginaceae. The name comes from the Ancient Greek "mouse's ear", which the foliage is thought to resemble. In the northern hemisphere they are colloquially known as forget-me-nots or scorpion grasses. ''Myosotis alpestris'' is the official flower of Alaska and Dalsland, Sweden. Plants of the genus are commonly confused with Chatham Islands' forget-me-nots, which belong to the related genus ''Myosotidium''. Description The genus was originally described by Carl Linnaeus. The type species is ''Myosotis scorpioides''. ''Myosotis'' species are annual or perennial herbaceous flowering plants with penta merous actinomorphic flowers with 5 sepals and petals. Flowers are typically 1 cm in diameter or less, flatly faced, coloured blue, pink, white or yellow with yellow centres and borne on scorpioid cymes. The foliage is alternate, and their roots are generally diffuse. They typically flower in spring or soon ...
