Question: Are the following plants members of the different families: Nerium and Mitchella?

Context paragraphs:
Pandanales: Pandanales (pandans or screw-pines) is the botanical name for an order of flowering plants placed in the monocot clade in the Angiosperm Phylogeny Group and Angiosperm Phylogeny Web systems.  Within the monocots Pandanales are grouped in the lilioid monocots where they are in a sister group relationship with the Dioscoreales.  Historically the order has consisted of a number of different families in different systems but modern classification of the order is based primarily on molecular phylogenetics despite diverse morphology which previously placed many of the families in other groupings based on apparent similarity.  Members of the order have a subtropical distribution and includes palms, trees, shrubs, and vines as well as herbaceous plants.  The order consists of 5 families, 36 genera and about 1,300 species.

Nerium: Nerium oleander is a shrub or small tree in the dogbane family Apocynaceae, toxic in all its parts.  It is the only species currently classified in the genus Nerium.  It is most commonly known as nerium or oleander, from its superficial resemblance to the unrelated olive "Olea".  It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested.  The ancient city of Volubilis in Morocco may have taken its name from the Berber name "oualilt" for the flower.  Oleander is one of the most poisonous commonly grown garden plants.

Mitchella: Mitchella is a genus of flowering plants in the Rubiaceae family.  It is found from China to temperate eastern Asia, and from eastern Canada to Guatemala.

Scrope v Grosvenor: Scrope v Grosvenor (1389) was one of the earliest heraldic law cases brought in England.  The case resulted from the fact that two different families were using the same undifferenced coat of arms.  In the 12th and 13th centuries, the composition of coats of arms was very simple.  Most shields consisted of only one charge and two tinctures, and there were times when two families bore the same coat of arms in the same jurisdiction.  In the fourteenth century, though, cases of two unrelated families bearing the same coat of arms became less tolerated.  When this happened, the monarch was usually called on to make a decision.

Tospovirus: The tospoviruses are a genus ("Tospovirus") of negative RNA virus found within the family "Bunyaviridae".  They are the sole group of plant infecting viruses in this family, as all other described members of the "Bunyaviridae" infect animals.  The genus takes its name from the discovery of "tomato spotted wilt virus" (TSWV) in Australia in 1919.  It remained the only member of the family until the early 1990s when genetic characterisation of viruses discovered in plants became more common.  There are now at least twenty viral species in the family with more being recorded and described on a relatively regular basis.  Together, these viruses have been documented infecting over eight hundred different plant species from 82 different families.

Load following power plant: A load following power plant, regarded as producing mid-merit or mid-priced electricity, is a power plant that adjusts its power output as demand for electricity fluctuates throughout the day.  Load following plants are typically in-between base load and peaking power plants in efficiency, speed of start up and shut down, construction cost, cost of electricity and capacity factor.

Chemokine receptor: Chemokine receptors are cytokine receptors found on the surface of certain cells that interact with a type of cytokine called a chemokine.  There have been 20 distinct chemokine receptors discovered in humans.  Each has a 7-transmembrane (7TM) structure and couples to G-protein for signal transduction within a cell, making them members of a large protein family of G protein-coupled receptors. Following interaction with their specific chemokine ligands, chemokine receptors trigger a flux in intracellular calcium (Ca) ions (calcium signaling).  This causes cell responses, including the onset of a process known as chemotaxis that traffics the cell to a desired location within the organism.  Chemokine receptors are divided into different families, CXC chemokine receptors, CC chemokine receptors, CX3C chemokine receptors and XC chemokine receptors that correspond to the 4 distinct subfamilies of chemokines they bind.  Four families of chemokine receptors differ in spacing of cysteine residues near N-terminal of the receptor.

List of glycoside hydrolase families: Glycoside hydrolases (O-Glycosyl hydrolases) EC 3.2.1.  are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety.  A classification system for glycosyl hydrolases, based on sequence similarity, has led to the definition of numerous different families.  This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site.  Because the fold of proteins is better conserved than their sequences, some of the families can be grouped in 'clans'.  As of October 2011, CAZy includes 128 families of glycosyl hydrolases and 14 clans.

Spiny eel: The name spiny eel is used to describe members of two different families of fish: the freshwater Mastacembelidae of Asia and Africa, and the marine (and generally deep sea) Notacanthidae.  Both are so-named because of their eel-like shape and sturdy fin spines.  These two families are not related and that the Notacanthiformes belong to the Superorder Elopimorpha, of which members are characterized by having a leptocephalus larvae.  The freshwater Mastacembelids do not share this characteristic and are popular specimens in the aquarium trade.

Raptorial: The term raptorial implies much the same as "predatory", but most often refers to modifications of an arthropod's foreleg that make it function for the grasping of prey while it is consumed, where the gripping surfaces are formed from the opposing faces of two successive leg segments (see illustration).  This is distinctly different from the grasping mechanism of a structure such as a scorpion's claw (a "chela") in which one of the opposing surfaces is an articulated digit, and not a leg segment.  While this is most widely known in mantises, similarly modified legs can be found in some crustaceans (e.g., mantis shrimp), and various insect families, such as Mantispidae, Belostomatidae, Nepidae, and Naucoridae (all members of these groups have raptorial forelegs).  There are numerous other lineages within various insect families that have raptorial forelegs, most commonly seen in the family Reduviidae, but also including several different families of flies, and a few thrips.  The arachnid lineage Amblypygi also has similar functioning pedipalps.
