Thalamiflorae
''Thalamiflorae'' is a historical grouping of dicotyledons, arranged in the De Candolle system and in the Bentham and Hooker system. This group was named and published well before internationally accepted rules for botanical nomenclature. In these systems, a family was indicated as "ordo", and modern rules of botanical nomenclature accept that as meaning a family rather than an order. rticle 18.2/sup> Family names have also since been standardized (most family names now end in -''aceae'').

Bentham And Hooker
A taxonomic system, the Bentham & Hooker system for seed plants, was published in Bentham and Hooker's ''Genera plantarum ad exemplaria imprimis in herbariis kewensibus servata definita'' in three volumes between 1862 and 1883. George Bentham (1800–1884) and Joseph Dalton Hooker (1817–1911) were British botanists who were closely affiliated to the Royal Botanic Gardens, Kew, in England. Their system of botanical taxonomy was based on the principle of natural affinities and is considered as pre-Darwinian as it does not take evolution into account. The ''Genera plantarum'' classified an estimated 97,205 species into 202 families and 7,569 genera. Summary The system recognises the following main groups: * Class DICOTYLEDONES **DICOTYLEDONUM POLYPETALE vol I ***: Series 1. Thalamiflorae ***: Series 2. Disciflorae ***: Series 3.

Dicotyledon
The dicotyledons, also known as dicots (or, more rarely, dicotyls), are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this group. The other group of flowering plants were called monocotyledons (or monocots), typically each having one cotyledon. Historically, these two groups formed the two divisions of the flowering plants. Largely from the 1990s onwards, molecular phylogenetic research confirmed what had already been suspected: that dicotyledons are not a group made up of all the descendants of a common ancestor (i.e., they are not a monophyletic group). Rather, a number of lineages, such as the magnoliids and groups now collectively known as the basal angiosperms, diverged earlier than the monocots did; in other words, monocots evolved from within the dicot ...

Delphinium
''Delphinium'' is a genus of about 300 species of annual and perennial flowering plants in the family (biology), family Ranunculaceae, native plant, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. The genus was erected by Carl Linnaeus. All members of the genus ''Delphinium'' are toxic to humans and livestock. The common name larkspur is shared between perennial ''Delphinium'' species and annual species of the genus ''Consolida''. Molecular data show that ''Consolida'', as well as another segregate genus, ''Aconitella'', are both embedded in ''Delphinium''. The genus name ''Delphinium'' derives from the Ancient Greek word () which means "dolphin", a name used in ''De Materia Medica'' for some kind of larkspur. Pedanius Dioscorides said the plant got its name because of its dolphin-shaped flowers. Habitat Species with short stems and few flowers such as ''Delphinium nuttallianum'' and ''Delphinium bicolor'' appear in habitats like p ...

Aquilegia
''Aquilegia'' (common names: granny's bonnet, columbine) is a genus of about 60–70 species of perennial plants that are found in meadows, woodlands, and at higher altitudes throughout the Northern Hemisphere, known for the spurred petals Puzey, J.R., Gerbode, S.J., Hodges, S.A., Kramer, E.M., Mahadevan, L. (2011) Evolution of ''Aquilegia'' spur length diversity through changes in cell anisotropy. Proceedings of the Royal Society B. of their flowers. Etymology The genus name Aquilegia comes from the Latin “Aquila”, or “eagle”; this is in obvious reference to the spurred, “hook” shapes within the blooms, that many gardeners say resemble an eagle's talons. Description Perennial herbs, with woody, erect stock, roots forming thick rhizomes. The basal leaves are compound, 1–3 ternate, blades 3-lobed -partite, and lobes lobulate and obtuse. The cauline leaves are similar to the basal ones, while the upper ones are bract like. The hermaphrodite (bisexual) flowers ...

Nigella
''Nigella'' is a genus of 18 species of annual plants in the family Ranunculaceae, native to Southern Europe, North Africa, South Asia, Southwest Asia and Middle East. Common names applied to members of this genus are nigella, devil-in-a-bush or love-in-a-mist. The species grow to tall, with finely divided leaves; the leaf segments are narrowly linear to threadlike. The flowers are white, yellow, pink, pale blue or pale purple, with five to ten petals. The fruit is a capsule composed of several united follicles, each containing numerous seeds; in some species (e.g. '' Nigella damascena''), the capsule is large and inflated. Uses Culinary The seeds of ''Nigella sativa'', known as ''kalonji'', black cumin, black caraway, black coriander, roman coriander, black onion seed, onion seed, charnushka, git (in historical Roman cuisine), or just nigella, are used as a spice and a condiment in South Asian cuisine, Ethiopian cuisine, Middle Eastern and Polish cuisines.

Trollius
''Trollius'' is a genus of about 30 species of flowering plants closely related to ''Ranunculus'', in the family Ranunculaceae. The common name of some species is globeflower or globe flower. The generic name is derived from the Swiss-German word "Trollblume", meaning a rounded flower. Native to the cool temperate regions of the Northern Hemisphere, with the greatest diversity of species in Asia, ''Trollius'' usually grow in heavy, wet clay soils. Description They are mostly herbaceous, fibrous rooted perennials with bright yellow, orange or lilac coloured flowers. The name "globe flower" refers to the petals of ''T. europaeus'' and ''T.'' × ''cultorum'' which are curved over the top of the flower, forming a globe. But ''T. pumilus'' has flatter flowers, and ''T. chinensis'' has open flowers with prominent stamens. Ecology All species of ''Trollius'' are poisonous to cattle and other livestock when fresh, but their acrid taste means they are usually left uneaten. They are, how ...

Caltha
''Caltha'' is a genus of rhizomatous perennial flowering plants in the family Ranunculaceae ("buttercup family"), to which ten species have been assigned. They occur in moist environments in temperate and cold regions of both the Northern and Southern Hemispheres. Their leaves are generally heart-shaped or kidney-shaped, or are characteristically diplophyllous (the auricles of the leaf blades form distinctly inflexed appendages). Flowers are star shaped and mostly yellow to white. True petals and nectaries are missing but the five or more sepals are distinctly colored. As usual in the buttercup family there is a circle of stamens around (two to twenty-five) free carpels. Description ''Caltha'' species are hairless, dwarf to medium size (1–80 cm high) perennial herbs, with alternate leaves. These leaves are simple (in all Northern Hemisphere species), or have one pair of lobes at the base (in ''C. sagittata'') which is mostly oriented at a straight angle to the larg ...

Helleboreae
Commonly known as hellebores (), the Eurasian genus ''Helleborus'' consists of approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. Despite names such as "winter rose", "Christmas rose" and "Lenten rose", hellebores are not closely related to the rose family (Rosaceae). Many hellebore species are poisonous. Description The flowers have five petal-like sepals surrounding a ring of small, cup-like nectaries which are actually petals modified to hold nectar. The sepals do not fall as petals would, but remain on the plant, sometimes for many months. Recent research in Spain suggests that the persistence of the sepals contributes to the development of the seeds. Taxonomy The genus was established by Carl Linnaeus in volume one of his ''Species Plantarum'' in 1753. The scientific name ''Helleborus'' could derive from the Ancient Greek word (), the common name for '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
