The Koninklijke Algemeene Vereniging voor Bloembollencultuur, translated from Dutch as the Royal General Association for Bulb Culture, but more commonly known world-wide by the acronym of KAVB, is a trade association for the bulb horticulture sector, and was established in 1860. The association has a rural organization, within which regional groups and departments are active. [1]
The main activities of the association is its collective protection of members interests, and knowledge - and provision of information, and specialized service.
The KAVB has approximately 2,200 members. Most of the members are independent entrepreneurs active in the introduction, production and trade of bulbs and bulbous flowers. [2] The association represents the majority of participants in the Netherlands participating in the bulb sector.
The bulb sector in the Netherlands has a strong position on the world market. Approximately 70% of the world's production and 75% of the trade are realized in the Netherlands. Moreover, the production of bulbs and bulbous flowers abroad is mostly in Dutch hands. At the rural secretariat of the KAVB 20 employees are operative. The majority have daily contacts with members, and governments. Regional secretaries support the association work for the departments and groups in the various regions. [3]
The KAVB acts as the International Cultivar Registration Authority (ICRA) for all Bulbous, cormous and tuberous-rooted ornamental plants, excluding Dahlia Cav., Lilium L., Narcissus L., Nerine Herb. and various Australian genera (1955)
The full list is as follows:
Moraea, the Cape tulips, is a genus of plants in the family Iridaceae, first described as a genus in 1758. The group is widespread across Africa, the Mediterranean, and central and southwestern Asia. The genus name is a tribute to the English botanist Robert More.
Dipcadi is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is widely distributed, occurring in southern Europe, most of Africa and the Middle East through to the Indian subcontinent.
Hippeastrum aulicum, the Lily of the Palace, is a bulbous perennial, in the family Amaryllidaceae, native to the Atlantic Forest and Cerrado ecoregions from Brazil to Paraguay, in South America.
This is an alphabetical list of useful timber trees, indigenous and exotic, growing in the Gauteng area of South Africa. These trees range in size up to some 1.5m DBH, such as Cedrus deodara, the Himalayan Cedar. Hobbyists will seek out even small pieces of highly valued timber, such as Buxus macowanii, the South African counterpart of Buxus sempervirens, for turnery or the making of boxes and small items. Despite the wealth of useful woods available in Gauteng, most of the trees, felled or fallen, are dumped or cut into short lengths for fuel. Trees grown in urban or suburban environments are rarely pruned and are consequently often knotty. Timber frequently holds nails, wire and spikes, attesting to a variety of abuse during the lifetime of a tree, and requiring the use of a metal detector by the sawmiller. Garden cuttings and dead leaves are occasionally piled next to trees and burnt, leaving charred scars and inclusions.
The anthophytes are a grouping of plant taxa bearing flower-like reproductive structures. They were formerly thought to be a clade comprising plants bearing flower-like structures. The group contained the angiosperms - the extant flowering plants, such as roses and grasses - as well as the Gnetales and the extinct Bennettitales.
Zanthoxyloideae is a subfamily of the family Rutaceae.
