Eidothea is a genus of two species of rainforest trees in New South Wales and Queensland, in eastern Australia, constituting part of the plant family Proteaceae.
 The plant family Proteaceae was named after the shape-shifting god Proteus of Greek Mythology.
 The genus name "Eidothea" refers to one of the three daughters of Proteus.
The Nippon orangequat is a cross between a Satsuma mandarin and a Meiwa kumquat, hybridized by Dr. Eugene May of the USDA and introduced in 1932, and is a member of the citrofortunella group.
 'Nippon' is the only named cultivar in existence.
Sadwavirus is a genus of viruses in the order Picornavirales, in the family Secoviridae.
 Plants (specifically Satsuma mandarin trees) serve as natural hosts.
 There is currently only one species in this genus: the type species "Satsuma dwarf virus".
 Diseases associated with this genus include: satsuma dwarf virus disease which causes spoon-shaped leaves on citrus tree.
 Symptoms are enations, multiple flushing, stunting or dwarfing, reduction in number and size of leaves and fruits.
 The name of this genus comes from its type species: Satsuma dwarf virus.
Kumquats (or cumquats in Australian English; ; or ) ("Citrus japonica") are a group of small fruit-bearing trees in the flowering plant family Rutaceae.
 They were previously classified as forming the now historical genus "Fortunella", or placed within "Citrus sensu lato".
The taxonomy of Liliaceae has had a complex history since the first description of this flowering plant family in the mid-eighteenth century.
 Originally, the Liliaceae or Lily family were defined as having a ""calix"" (perianth) of six equal-coloured parts, six stamens, a single style, and a superior, three-chambered (trilocular) ovary turning into a capsule fruit at maturity.
 The taxonomic circumscription of the Liliaceae family progressively expanded until it became the largest plant family and also extremely diverse, being somewhat arbitrarily defined as all species of plants with six tepals and a superior ovary.
 It eventually came to encompass about 300 genera and 4,500 species, and was thus a "catch-all" and hence paraphyletic taxon.
 Only since the more modern taxonomic systems developed by the Angiosperm Phylogeny Group (APG) and based on phylogenetic principles, has it been possible to identify the many separate taxonomic groupings within the original family and redistribute them, leaving a relatively small core as the modern Liliaceae family, with fifteen genera and 600 species.
Cold-hardy citrus is citrus with increased frost tolerance which may be cultivated far beyond traditional citrus growing regions.
 Citrus species and citrus hybrids typically described as cold-hardy generally display an ability to withstand wintertime temperatures below -5 to .
 Cold-hardy citrus may be generally accepted 'true' species (e.g. Satsuma mandarin, Kumquat) or hybrids (e.g. Citrange) involving various other citrus species.
 All citrus fruits are technically edible, though some have bitter flavors often regarded as unpleasant, and this variability is also seen in cold-hardy citrus fruits.
 Those listed as "inedible fresh" or "semi-edible" can (like all citrus) be cooked to make marmalade.
The iyokan (伊予柑 - C. × iyo), also known as "anadomikan" (穴門みかん) and "Gokaku no Iyokan", is a Japanese citrus fruit, similar in appearance to a mandarin orange.
 It is the second most widely produced citrus fruit in Japan after the satsuma mandarin.
Prosartes maculata is a North American species of plants in the lily family with the common names yellow mandarin, spotted mandarin or nodding mandarin.
 It is a perennial plant that flowers in the spring.
Citrus unshiu is a seedless and easy-peeling citrus species, also known as unshu mikan, cold hardy mandarin, satsuma mandarin, satsuma orange, and tangerine.
 It is of Chinese origin, but was introduced to the West via Japan.
Strawberry mottle virus (SMV) is a pathogenic plant virus in "Secoviridae", a family of plant-infecting picornaviruses.
 It is not yet assigned to a genus.
 Virions are isometric, approximately 28 nm in diameter, and contain two RNA strands (RNA1 and RNA2) equal to about 12,600 nucleotides in length.
 The polyprotein of RNA1 contains regions identified as helicase, protease, RNA-dependent RNA polymerase and a viral genome-linked protein while RNA2 shows similarities to the large coat protein domain of the Satsuma dwarf virus.
