sentences: A cultivar group – represented in a botanical name by the symbol Group or Gp (previously cultivar-group) – is a formal category for cultivated plants that share a defined characteristic according to the "International Code of Nomenclature for Cultivated Plants" ("ICNCP").
 "Group" or "Gp" is always written with a capital "G" in a botanical name, or "epithet".
 The cultivar group is not italicized in a plant's name.
 The "ICNCP" introduced the symbol "Group" in 2004, as a replacement for the lengthy and hyphenated "cultivar-group", which had previously been the category's name since 1995.
 The non-standard abbreviation cv.
 group is also sometimes encountered.
Colocasia esculenta is a tropical plant grown primarily for its edible corms, the root vegetables most commonly known as taro.
 It is believed to be one of the earliest cultivated plants.
 Linnaeus originally described two species which are now known as "Colocasia esculenta" and "Colocasia antiquorum" of the cultivated plants that are known by many names including eddoes, dasheen, taro and madumbi, but many later botanists consider them all to be members of a single, very variable species, the correct name for which is "Colocasia esculenta".
The Pendlebury Library of Music is the library of the Faculty of Music, University of Cambridge, England.
 The current building was completed in 1984, and was designed by Sir Leslie Martin.
 The library is located next to the West Road Concert Hall and the Faculty of Music's old building on the Sidgwick Site, West Road, Cambridge.
 The current classification system is somewhat similar to the one used for music at Cambridge University Library's Music Collections, and has a basic classification approach of a three-digit number.
 The library is open to all members of the university.
The term grex (pl.
 greges or grexes; abbreviation gx), derived from the Latin noun "grex, gregis" meaning 'flock', has been coined to expand botanical nomenclature to describe hybrids of orchids, based solely on their parentage.
 Grex names are one of the three categories of plant names governed by the International Code of Nomenclature for Cultivated Plants; within a grex the "cultivar group" category can be used to refer to plants by their shared characteristics (rather than by their parentage), and individual orchid plants can be selected (and propagated) and named as cultivars.
The term cultivar most commonly refers to an assemblage of plants selected for desirable characteristics that are maintained during propagation.
 More generally, "cultivar" refers to the most basic classification category of cultivated plants governed by the ICNCP.
 Most cultivars have arisen in cultivation, but a few are special selections from the wild.
Rosa" × "odorata or Rosa odorata is a member of the genus "Rosa" native to Yunnan in Southwest China, whose taxonomy has been confused.
 It has been considered to be hybrid between "Rosa gigantea" and "Rosa chinensis", or as a quite rare wild species that includes "R. gigantea".
 The wild forms are cultivated to some extent.
 Cultivars were developed in China in ancient times from "R. chinensis" crosses, and these have been important in the ancestry of the tea-scented China roses, also called tea roses, and their descendants the hybrid tea roses.
Arca-Net is a European Ark-network of institutions that keep endangered livestock breeds or rare cultivated plants, making them known to the public.
 Arca-Net is designed for a broad public and in form of a virtual guide, at any time available via Internet.
 Descriptions of the institutions, directions on getting there, offers and information on the livestock breeds kept and plants cultivated, their distribution, status of endangering and their history are available from Arca-Net.
A Web query topic classification/categorization is a problem in information science.
 The task is to assign a Web search query to one or more predefined categories, based on its topics.
 The importance of query classification is underscored by many services provided by Web search.
 A direct application is to provide better search result pages for users with interests of different categories.
 For example, the users issuing a Web query “"apple"” might expect to see Web pages related to the fruit apple, or they may prefer to see products or news related to the computer company.
 Online advertisement services can rely on the query classification results to promote different products more accurately.
 Search result pages can be grouped according to the categories predicted by a query classification algorithm.
 However, the computation of query classification is non-trivial.
 Different from the document classification tasks, queries submitted by Web search users are usually short and ambiguous; also the meanings of the queries are evolving over time.
 Therefore, query topic classification is much more difficult than traditional document classification tasks.
Tropical savanna climate or tropical wet and dry climate is a type of climate that corresponds to the Köppen climate classification categories "Aw" and "As".
A botanical name is a formal scientific name conforming to the "International Code of Nomenclature for algae, fungi, and plants" (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the "International Code of Nomenclature for Cultivated Plants" (ICNCP).
 The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)."
