Galea (botany)
A galea is an overhanging, helmet-shaped, part of the flower that protects the reproductive parts from precipitation, wind, or unwanted visitors. The galea is composed of one or more petals or sepals that have either fused or folded together. The name is taken from the same word for a Roman soldier's helmet. The specific epithet ''galeatus(-a-um)'', ''galeiformis(-e)'', ''galeritus(-a-um)'' or ''galericulatus(-a-um)'' can be found in nomenclature, referring to a prominent helmet-shaped feature in the organism. There are several genera that have been named to reflect this characteristic: ''Galeandra'', ''Galearia ''Galearia'' is a genus of plant of the family Pandaceae. It is native to Indochina, insular Southeast Asia, New Guinea and the Solomon Islands.

Neotinea Lactea Balma
''Neotinea'' is a genus of flowering plants from the orchid family, Orchidaceae. It is native to much of Europe, the Mediterranean region, and the islands of the eastern Atlantic, from the Canaries, Madeira and Ireland east to Iran and Western Siberia. Description The Neotinea species are relatively low-growing and small, perennial herbaceous plants. They form ovoid tubers as outlasting organs, so they belong to the geophytes. Each plant has two tubers, one old (previous year) and one new (this year). The erect stem is often slightly bluish. There are two to four leaves in a basal rosette and one or two more on the stem, these can be spotted or unspotted. The densely flowered inflorescence is cylindrical in outline, sometimes conical. The bracts are formed as membranous bracts. The hermaphrodite flowers are relatively small, they are greenish white, straw-colored, whitish or pink in color, zygomorphic and triad. The bracts, especially the lip, are often mottled darker pink to pur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Sepal
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 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'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Galea (helmet)
A ''galea'' (, from Greek γαλέη, ''galéē'', "weasel, marten") was a Roman soldier's helmet. Some gladiators, specifically myrmillones, also wore bronze ''galeae'' with face masks and decorations, often a fish on its crest. The exact form or design of the helmet varied significantly over time, between differing unit types, and also between individual examples – pre-industrial production was by hand – so it is not certain to what degree there was any standardization even under the Roman Empire. Originally, Roman helmets were influenced by the neighboring Etruscans, people who utilised the "Nasua" type helmets. The Greeks in the south also influenced Roman design in its early history. The primary evidence is scattered archaeological finds, which are often damaged or incomplete. There are similarities of form and function between them. Helmet types H. Russell Robinson in his book ''The Armour of Imperial Rome'', published in 1975, classified into broad divisions the v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epithet
An epithet (, ), also byname, is a descriptive term (word or phrase) known for accompanying or occurring in place of a name and having entered common usage. It has various shades of meaning when applied to seemingly real or fictitious people, divinities, objects, and binomial nomenclature. It can also be a descriptive title: for example, Pallas Athena, Phoebus Apollo, Alfred the Great, Suleiman the Magnificent, and Władysław I the Elbow-high. Many English monarchs have traditional epithets: some of the best known are Edward the Confessor, William the Conqueror, Richard the Lionheart, Æthelred the Unready, John Lackland and Bloody Mary. The word ''epithet'' can also refer to an abusive, defamatory, or derogatory phrase. This use as a euphemism is criticized by Martin Manser and other proponents of linguistic prescription. H. W. Fowler complained that "epithet is suffering a vulgarization that is giving it an abusive imputation." Linguistics Epithets are sometimes at ...

Plant Morphology
Phytomorphology is the study of the morphology (biology), physical form and external structure of plants.Raven, P. H., R. F. Evert, & S. E. Eichhorn. ''Biology of Plants'', 7th ed., page 9. (New York: W. H. Freeman, 2005). . This is usually considered distinct from plant anatomy, which is the study of the internal Anatomy, structure of plants, especially at the microscopic level. Plant morphology is useful in the visual identification of plants. Recent studies in molecular biology started to investigate the molecular processes involved in determining the conservation and diversification of plant morphologies. In these studies transcriptome conservation patterns were found to mark crucial ontogenetic transitions during the plant life cycle which may result in evolutionary constraints limiting diversification. Scope Plant morphology "represents a study of the development, form, and structure of plants, and, by implication, an attempt to interpret these on the basis of similarit ...
