Ornamental horticulture is the branch of horticulture concerned with cultivating plants of all kinds for show and to satisfy the eye rather than for food (Bailey, 1960). It includes floriculture, the culture of trees for shades, display and landscape gardening. Gill (1988) defined taxonomy as a study aimed at producing a system of classification of biological organisms, which best reflects the totality of their similarities and differences. According to
him, there are three inter-related aspects of taxonomy namely: Identification, Nomenclature and Classification. Identification deals with the determination of a taxon as being identical or similar to another and already known organisms. Nomenclature on the other hand has to do with determination of the correct name for the organisms and is governed by International Code of Botanical Nomenclature. It permits only a single valid name for each plant. Classification is the placing of plants in groups or categories according to particular plan or system.
The objectives of taxonomy are to provide: a convenient method of identifying, naming and describing plants, a classification which as far as possible express the natural relationships of organisms, detect evolution at work, discovering its processes and interpreting its results, an inventory of plant resources-local, regional and continental and to provide an integrating and unifying role in the training of biology.

The concept of Centers of Origin given by Russian scientist N.I. Vavilov (1935) is based on his studies of vast collection of plants at the Institute of Plant  Industry, Leningrad. According to him, crop plants evolved from wild species in the areas showing great diversity and termed them as primary Centers of Origin; but in some areas, certain crop species show considerable diversity of forms although they did not originate their, such areas are known as secondary center of origin of these species. He identified 8 primary centers (Chinese, Indian, Inner Asiatic, Asia Minor, Mediterranean, Abyssinian, South Mexico, Central America and South America Andes Center) and three sub-centers (Indo-Malayan, Chilean and Brazilian-Paraguayan sub-center) of origin for crop plants. Basilevskaya (1960) first investigated the geographical origin of garden plants. Coats (1968) who first stressed out the ornamental herbs whereas Hui-Lin-Li (1974) wrote about the introduction of woody plants. According to Tay (2007) survey of thirty common flowers and their related species show a similar pattern of concentrated occurrence of species in certain geographic regions.
Exploration and exploitation of gene centers need to be proceed with the systematic cooperation of taxonomists, geneticists and plant pathologists. The 17 centers of origin identified for different flower and ornamental crops are
given (Table 2.1)

3.1. History and Development of Plant Classification
The botanical term “Angiosperm”, from the Ancient Greek ‘angeíon’ (receptacle, vessel) and seed, was coined in the form Angiospermae by Paul Hermann in 1690, as the name of that one of his primary divisions of the plant
kingdom.
This included flowering plants possessing seeds enclosed in capsules, distinguished from his Gymnospermae, or flowering plants with achenial or schizocarpic fruits, the whole fruit or each of its pieces being here regarded as a seed and naked.
Its use with any approach to its modern scope only became possible after 1827, when Robert Brown established the existence of truly naked ovules in the Cycadeae and Coniferae, and applied to them the name gymnosperms. From that time onwards, so long as these Gymnosperms were, as was usual, reckoned as dicotyledonous flowering plants, the term Angiosperm was used antithetically by botanical writers, with varying scope, as a group-name for other dicotyledonous plants.
In 1851, Hofmeister discovered the changes occurring in the embryo-sac of flowering plants, and determined the correct relationships of these to the Cryptogamia
