Question: Do the words Cymbidium and Prunus have to do with the plant kingdom?
Context: Odontoglossum ringspot virus (ORSV) is a plant pathogenic virus.  It is one of the most common viruses affecting cultivated orchids, perhaps second only to the "Cymbidium mosaic virus".  It causes spots on leaves and colored streaks on flowers.  If a plant is also infected with the "Cymbidium mosaic virus", it can lead to a condition called blossom brown necrotic streak.  Its genome has been sequenced and contains approximately 6600 nucleotides organized into four open reading frames. Its similarity to other tobamoviruses can be seen from the genetic data and the (limited) ability of a "Tobacco mosaic virus" modified to contain ORSV movement protein to infect tobacco.  However, only about 60% of the nucleotides in ORSV are identical with "Tobacco mosaic virus". The Northern Cymbidium (Cymbidium madidum) is a species of plant in the Orchidaceae family, also known as the Buttercup Orchid and Moist Forest Cymbidium. Yo Takenaka (竹中 要 Takenaka Yō, 1903–1966) was a Japanese plant geneticist and a Professor of Department of Cell Genetics, National Institute of Genetics.  He is notable for researching the phylogenetic classification of cherry blossom.  He discovered that "Prunus × yedoensis" is a crossbreed of two wild species of Japanese cherry; "Prunus spachiana" forma "ascendens" (Edo higan) and "Prunus speciosa" (Oshima zakura) by crossing experiments.  He was also known as a researcher on Japanese morning glory and Nicotiana. Cymbidium tracyanum (Tracy's Cymbidium) is a species of orchid.  It flowers in the fall and winter with large, fragrant 4" flowers.  This is a large sized, cold to cool growing plant that can withstand near-freezing temperatures. Prunus" × "yedoensis, Prunus" × "yedoensis" 'Somei-yoshino' or Yoshino cherry (Japanese: 染井吉野 "Somei Yoshino") (synonym Cerasus" × "yedoensis") is a hybrid cherry of between "Prunus speciosa" ("Oshima zakura") as father plant and "Prunus pendula" f. "ascendens" ("Edo higan") as mother.  It occurs as a natural or artificial hybrid in Japan and is now one of the most popular and widely planted cultivated flowering cherries ("sakura") in temperate climates worldwide.  It is a clone from a single tree and propagated by grafting to all over the world. A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place".  Examples commonly are plants unwanted in human-controlled settings, such as farm fields, gardens, lawns, and parks. Taxonomically, the term "weed" has no botanical significance, because a plant that is a weed in one context is "not" a weed when growing in a situation where it "is" in fact wanted, and where one species of plant is a valuable crop plant, another species in the same genus might be a serious weed, such as a wild bramble growing among cultivated loganberries.  Many plants that people widely regard as weeds also are intentionally grown in gardens and other cultivated settings, in which case they are sometimes called beneficial weeds.  The term "weed" also is applied to any plant that grows or reproduces aggressively, or is invasive outside its native habitat.  More broadly "weed" occasionally is applied pejoratively to species outside the plant kingdom, species that can survive in diverse environments and reproduce quickly; in this sense it has even been applied to humans. In biology, a phylum ( ; plural: phyla) is a level of classification or taxonomic rank below Kingdom and above Class.  Traditionally, in botany the term division has been used instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent.  Depending on definitions, the animal kingdom Animalia or Metazoa contains approximately 35 phyla, the plant kingdom Plantae contains about 12, and the fungus kingdom Fungi contains about 7 phyla.  Current research in phylogenetics is uncovering the relationships between phyla, which are contained in larger clades, like Ecdysozoa and Embryophyta. Cymbidium , or boat orchid, is a genus of 52 evergreen species in the orchid family Orchidaceae.  The new Latin genus name is derived from the Latin "cymba" meaning boat.  Its first known use was in 1815. Prunus is a genus of trees and shrubs, which includes the plums, cherries, peaches, nectarines, apricots and almonds. The aloe-leafed cymbidium (Cymbidium aloifolium) is a species of orchid found in Asia, especially China and southeast Asia from Burma to Sumatra.  It can be found growing between rocks or on another plant.  The word "cymbidium" comes from the Greek "kumbos" meaning "hole, cavity" and the Latin specific name is just a translation of the English "aloe-leafed".
