In the Standard Generalized Markup Language (SGML), an entity is a primitive data type, which associates a string with either a unique alias (such as a user-specified name) or an SGML reserved word (such as codice_1).
 Entities are foundational to the organizational structure and definition of SGML documents.
 The SGML specification defines numerous entity types, which are distinguished by keyword qualifiers and context.
 An entity string value may variously consist of plain text, SGML tags, and/or references to previously-defined entities.
 Certain entity types may also invoke external documents.
 Entities are called by reference.
Dodonaea is a genus of about 70 species of flowering plants, often known as hop-bushes, in the soapberry family, Sapindaceae.
 It has a cosmopolitan distribution in tropical, subtropical and warm temperate regions of Africa, the Americas, southern Asia and Australasia.
 By far the highest species diversity is in Australia.
 The genus is named after Rembert Dodoens, also known as Rembertus Dodonaeus.
Petunidin (Pt), like Europinidin and Malvidin, is derived from Delphinidin and is an O-methylated anthocyanidin of the 3-hydroxy type.
 It is a natural organic compound, a dark-red or purple water-soluble pigment found in many redberries including chokeberries ("Aronia sp"), Saskatoon berries ("Amelanchier alnifolia") or different species of grape (for instance "Vitis vinifera", or muscadine, "Vitis rotundifolia"), and also part of the pigments responsible for the petal colors in many flowers.
 This pigment gives the Indigo Rose tomatoes the majority of their deep purple color when the fruits are exposed to sunlight.
 The name of the molecule itself is derived from the word Petunia.
A molecular entity is "any constitutionally or isotopically distinct atom, molecule, ion, ion pair, radical, radical ion, complex, conformer, etc., identifiable as a separately distinguishable entity".
 A molecular entity is any singular entity, irrespective of its nature, used to concisely express any type of chemical particle that can exemplify some process: for example, atoms, molecules, ions, etc. can all undergo a chemical reaction.
Petunia is genus of 35 species of flowering plants of South American origin, closely related to tobacco, cape gooseberries, tomatoes, deadly nightshades, potatoes and chili peppers in the same family, Solanaceae.
 The popular flower of the same name derived its epithet from the French, which took the word "petun", meaning "tobacco," from a Tupi–Guarani language.
 An annual, most of the varieties seen in gardens are hybrids ("P." × "atkinsiana", also known as "P." × "hybrida").
In relation to juristic persons, the constitutional documents (sometimes referred to as the charter documents) of the entity are the documents which define the existence of the entity and regulate the structure and control of the entity and its members.
 The precise form of the constitutional documents depends upon the type of entity.
An "Entity Bean" is a type of Enterprise JavaBean, a server-side Java EE component, that represents persistent data maintained in a database.
 An entity bean can manage its own persistence (Bean managed persistence) or can delegate this function to its EJB Container (Container managed persistence).
 An entity bean is identified by a primary key.
 If the container in which an entity bean is hosted crashes, the entity bean, its primary key, and any remote references survive the crash.
A Gesellschaft mit beschränkter Haftung (] , abbreviated GmbH ] and also GesmbH in Austria) is a type of legal entity very common in Germany, Austria, Switzerland (where it is equivalent to a S.à r.l.) and Liechtenstein.
 In the United States, the equivalent type of entity is the limited liability company (LLC).
 The name of the GmbH form emphasizes the fact that the owners ("Gesellschafter", also known as members) of the entity are not personally liable for the company's debts.
 "GmbH"s are considered legal persons under German and Austrian law.
 Other variations include mbH (used when the term "Gesellschaft" is part of the company name itself), and gGmbH ("gemeinnützige" GmbH) for non-profit companies.
A Bahamas Executive Entity, sometimes referred to simply as an Executive Entity, is designed to encaspsulate powers currently existing in wealth management and estate planning structures within a new form of legal entity.
 The Executive Entity was born out of legislation passed by The Commonwealth of The Bahamas and which came into force on 2 February 2012.
 At the time of its statutory introduction, the Executive Entity was considered the first of its type in the world.
Petunia" × "atkinsiana (synonym: "Petunia" × "hybrida") is a "Petunia" plant "nothospecies" (hybrid), which encompasses all hybrid species of petunia between "P. axillaris" and "P. integrifolia".
 Most of the petunias sold for cultivation in home gardens are this type and belong to this nothospecies.
