Question: Is a Kumquat a member of the Tetracentron genus?
Context: Tetracentron is a genus of flowering plant, the sole living species being Tetracentron sinense.  It was formerly considered the sole genus in the family Tetracentraceae, though modern botanists include it in the family Trochodendraceae together with the genus "Trochodendron". Calamondin (× "Citrofortunella microcarpa" or × "Citrofortunella mitis") is an important citrofortunella, meaning that it is an intergenetic hybrid between a member of the genus "Citrus" (in this case probably the mandarin orange) and the kumquat, formerly considered as belonging to a separate genus "Fortunella". 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. Eosalmo is a genus of extinct salmon which lived during the Eocene epoch.  The genus was first described in 1977 from fossils found in lacustrine deposits in Driftwood Canyon Provincial Park, near Smithers, British Columbia, Canada.  Fossils from this genus have also been found at sites in Princeton, British Columbia, the McAbee Fossil Beds in B.C., and Republic, Washington, USA.  When first described the genus was thought to be intermediate in form to the living salmon subfamilies Salmoninae (trout and salmon) and Thymallinae (graylings).  More recent review of the genus has placed "Eosalmo" as the most primitive member of the Salmoninae subfamily.  Fossils found in Driftwood Canyon Provincial Park display a full range of individuals from young juveniles through adults.  This range indicates that the genus was completely freshwater dwelling and did not spend time in saltwater. 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". Candidodon is an extinct genus of notosuchian mesoeucrocodylian. Fossils have been found of Early Cretaceous age from Brazil.  The genus is characterized by a particularly elongate pair of choanae in its palate.  It has been named the type genus of the family Candidodontidae, first constructed in 2004.  It was initially assigned to the family with a proposed sister genus, "Mariliasuchus", but a recent phylogenetic analysis has shown that "Mariliasuchus" may instead be closer in relation to "Comahuesuchus" than to "Candidodon" and thus a member of the family Comahuesuchidae.  If this is true, "Candidodon" would be the only member of the family Candidodontidae. Nannizziopsis guarroi was first discovered in Spain in 2010 and was classified as "Chrysosporium guarroi", a member of the anamorphic genus "Chrysosporium" in the family Onygenaceae.  Etymologically, the species epithet "guarroi" honours Professor Josep Guarro in recognition of his extensive mycological work including on the genus "Chrysosporium".  Skin samples taken from pet green iguanas suffering from dermatomycosis were sent to a laboratory for analysis.  Five species were isolated and morphologic studies identified the fungus causing the mycoses as a member of the anamorphic species of "Chrysosporium".  Further investigation of these species using a combination of morphological, cultural and molecular studies showed that they were not identical to any previously described species within the genus "Chrysosporium" so they were classified as a new species "Chrysosporium guarroi"sp.  nov.  The delineation of species in the genus "Chrysosporium" and their assignment to higher taxonomic levels can be challenging due to the marked morphological simplicity of these fungi.  Increased scrutiny of strains of these fungi using molecular genetic tools has revealed numerous hidden species and unexpected relationships. Kapes is an extinct genus of procolophonid parareptile from the Lower and Middle Triassic of the United Kingdom and Russia.  It is a member of the subfamily Procolophoninae.  The type species "K. amaenus" was named in 1975 from the banks of the Vychegda River in the Komi Republic of Russia.  In 1983, a new species was brought into the genus, "K. majmesculae".  "K. majmesculae" was first named in 1968 as a member of the genus "Tichvinskia".  A third Russian species, "K. serotinus", was named in 1991.  In 2002, "Kapes bentoni" was named from the Middle Triassic Otter Sandstone Formation of Devon, England, extending the geographic range of "Kapes".  In the same paper, "K. serotinus" was synonymized with "K. majmesculae" and another Russian species was assigned to "Kapes" called "K. komiensis".  "K. komiensis" was first named in 1975 (in the same paper "K. amaenus" was named in) as a member of the genus "Macrophon". Trochodendron aralioides, sometimes colloquially called "wheel tree", is a flowering plant and the sole living species in the genus "Trochodendron", which also includes several extinct species.  It was also often considered the sole species in the family Trochodendraceae, though botanists now include the distinct genus "Tetracentron" in the same family.  "T.aralioides" is native to Japan, southern Korea and Taiwan. Trochodendron is a genus of flowering plants with one living species, "Trochodendron aralioides", and six extinct species known from the fossil record.  It was often considered the sole genus in the family Trochodendraceae, though botanists now also include the distinct genus "Tetracentron" in the family Trochodendraceae.
