Clematis is a genus of about 380 species within the buttercup family, Ranunculaceae. Their garden hybrids and cultivars have been popular among gardeners, beginning with Clematis 'Jackmanii', a garden staple since 1862; more cultivars are being produced constantly. They are mainly of Chinese and Japanese origin.
Nyctanthes arbor-tristis is a species of Nyctanthes native to South Asia and Southeast Asia. It is commonly known as night-blooming jasmine, tree of sadness, tree of sorrow, hengra bubar, coral jasmine and in Singapore seri gading. Despite its common name, the species is not a "true jasmine" and not of the genus Jasminum.
An EPPO code, formerly known as a Bayer code, is an encoded identifier that is used by the European and Mediterranean Plant Protection Organization (EPPO), in a system designed to uniquely identify organisms – namely plants, pests and pathogens – that are important to agriculture and crop protection. EPPO codes are a core component of a database of names, both scientific and vernacular. Although originally started by the Bayer Corporation, the official list of codes is now maintained by EPPO.
The European and Mediterranean Plant Protection Organization (EPPO) is an intergovernmental organisation responsible for European cooperation in plant protection in the European and Mediterranean region. Founded on April 18, 1951 and based in Paris, France, EPPO is the Regional Plant Protection Organization (RPPO) for Europe under the International Plant Protection Convention (IPPC).
Clematis vitalba is a shrub of the family Ranunculaceae.
Curtobacterium flaccumfaciens is a Gram-positive bacterium that causes disease on a variety of plants. Gram-positive bacteria characteristics include small irregular rods, lateral flagella, the ability to persist in aerobic environments, and cells containing catalase. In the interest of studying pathogenicity in plants, this species is broken down further into pathovars, which help to better describe the pathogen.
Impatiens necrotic spot orthotospovirus(INSV) is a plant pathogenic virus of the order Bunyavirales. It was originally believed to be another strain of Tomato spotted wilt virus, but genetic investigations revealed them to be separate viruses. It is a negative-strand RNA virus which has a tripartite genome. It is largely spread by the insect vector of the western flower thrips. The virus infects more than 648 species of plants including important horticultural and agricultural species such as fuchsia, tomato, orchids, and lettuce (especially romaine). As the name implies, the main symptom on plants is necrotic spots that appear on the leaves. The INSV virus infects by injecting the RNA the virus contains into the cell which then starts using the cell resources to transcribe what the virus RNA states. Viral infection can often result in the death of the plant. The disease is mainly controlled by the elimination of the western flower thrip vector and by destroying any infected plant material.
Orthotospovirus is a genus of negative-strand RNA viruses, in the family Tospoviridae of the order Bunyavirales, which infects plants. Tospoviruses take their name from the species Tomato spotted wilt orthotospovirus (TSWV) which was discovered in Australia in 1919. TSWV remained the only known member of the family until the early 1990s when genetic characterisation of plant viruses became more common. There are now at least twenty species in the genus with more being discovered on a regular basis. Member viruses infect over eight hundred plant species from 82 different families.
Diabrotica speciosa, also known as the cucurbit beetle and in Spanish as vaquita de San Antonio is an insect pest native to South America. Its larvae feed on the roots of crops. The cucurbit beetle is also known to transmit several viruses such as comoviruses and different mosaic viruses. This is native to South America and is now distributed in Central America and other global areas.
Clematis integrifolia is a flowering vine of the genus Clematis. Like many members of that genus, it is prized by gardeners for its showy flowers. C. integrifolia bears nodding, urn-shaped blue flowers in summer that are 1.5 inches wide. It is a fairly short variety, growing only to 3 feet high. It is native to Europe and Asia. In the US it grows best in American Horticultural Society zones 8 to 1.
Rhus aromatica, the fragrant sumac, is a deciduous shrub in the family Anacardiaceae native to North America. It is found in southern Canada and nearly all of the lower 48 states except peninsular Florida.
Mastrevirus is a genus of ssDNA viruses, in the family Geminiviridae. Mostly monocotyledonous plants serve as natural hosts. They are vectored by planthoppers. There are 45 species in this genus. Diseases associated with this genus include: maize streak virus: maize streak disease (MSD).
Aria graeca, also known as the Greek whitebeam and fan-leaved service-tree, is a species of whitebeam, in the rose family (Rosaceae).
Tomato spotted wilt orthotospovirus (TSWV) is a spherical negative-sense RNA virus. Transmitted by thrips, it causes serious losses in economically important crops and it is one of the most economically devastating plant viruses in the world.
Takahashia japonica - the string cottony scale - is an insect pest of ornamental- and economic trees in the Coccidae family. It is a pest of quarantine significance in the EPPO area.
Primula × polyantha, the polyanthus primrose or false oxlip, is a naturally occurring hybrid species of flowering plant in the family Primulaceae. It is the result of crosses between Primula veris and Primula vulgaris. It is native to Europe, found where the parent species' ranges overlap, and many artificial hybrid cultivars have also been created for the garden trade. Naturally‑occurring individuals tend to have yellow flowers, while a wide range of flower colors has been developed in the cultivars over the centuries.
Beaumontia grandiflora, the Easter lily vine, herald's trumpet, or Nepal trumpet flower, is a species of flowering plant in the family Apocynaceae. It is native to the eastern Indian Subcontinent, southern China, and mainland Southeast Asia, and has been introduced to a number of locales in Central America. With its vining habit and trumpet-shaped flowers it is widely cultivated as an ornamental.
Limonium platyphyllum, the broad-leaved statice, or florist's sea lavender, is a species of flowering plant in the family Plumbaginaceae. It is native to the Black Sea region; Bulgaria, Romania, Ukraine, Crimea, south and east European Russia, and the Caucasus, and it has been introduced to Great Britain. A perennial halophyte 60 to 75 cm tall, it is widely available from commercial suppliers. There are a number of cultivars, including the well-known 'Violetta' which has darker petals.
Clematis × aromatica, the scented clematis, is a hybrid species of flowering plant in the family Ranunculaceae. Its parents are Clematis flammula and Clematis integrifolia. A non-clinging perennial with strongly scented flowers, it is widely available from commercial nurseries.
Linum tenuifolium, the narrow-leaved flax, is a species of flowering plant in the family Linaceae. It is native to central and southern Europe, the Black Sea and Caucasus area, and the northern Middle East as far as northwestern Iran. A perennial, it is generally found in rocky, alkaline, dry situations, and is thought to have spread out from relict European rocky steppes.
