Question: Are Myrtus and Hyacinthella both types of genus?

Context paragraphs:
Pseudechis: The genus Pseudechis contains the group of elapids commonly referred to as the black snakes.  These snakes are found in every Australian state with the exception of Tasmania and some species are found in Papua New Guinea.  They inhabit a variety of habitat types, from arid areas to swampland.  All species are dangerous ("Pseudechis" signifying "like a viper", Greek "echis") and can inflict a potentially lethal bite.  Most snakes in this genus reach about 2 metres and vary in colour.  Some species are brown, where others are black.  The most recognisable and widespread species in the genus are the red-bellied black snake ("Pseudechis porphyriacus") and the Mulga snake (king brown) ("Pseudechis australis").  These snakes feed on lizards, frogs, birds, small mammals and even other snakes.  All species lay eggs, except the red-bellied black snake.  The genus "Pailsus" is a synonym of "Pseudechis", and more work is needed to understand species limits among the smaller species of the group.

List of cloud types: The list of cloud types is a summarisation of the modern systems of cloud classification used in the troposphere, stratosphere, and mesosphere.  The ten basic genus-types in the troposphere have Latin names derived from five physical "forms".  These are, in approximate ascending order of instability or convective activity: "stratiform" sheets; "cirriform" wisps and patches; "stratocumuliform" patches, rolls, and ripples; "cumuliform" heaps and tufts, and "cumulonimbiform" towers that often have complex structures.  The forms are cross-classified by altitude range or level into ten basic genus types.  Most genera are divided into "species", some of which are common to more than one genus.  Most genera and species can be subdivided into "varieties", also with Latin names, some of which are common to more than one genus or species.  The essentials of the modern nomenclature system for tropospheric clouds were proposed by Luke Howard, a British manufacturing chemist and an amateur meteorologist with broad interests in science, in an 1802 presentation to the Askesian Society.  Since 1890, clouds have been classified and illustrated in cloud atlases.  Mesospheric and stratospheric clouds have their own classifications with common names for the major types and alpha-numeric nomenclature for the subtypes.

Attalea (palm): Attalea is a large genus of palms native to Mexico, the Caribbean, Central and South America.  This pinnately leaved, non-spiny genus includes both small palms lacking an aboveground stem and large trees.  The genus has a complicated taxonomic history, and has often been split into four or five genera based on differences in the male flowers.  Since the genera can only be distinguished on the basis of their male flowers, the existence of intermediate flower types and the existence of hybrids between different genera has been used as an argument for keeping them all in the same genus.  This has been supported by a recent molecular phylogeny.

Hyacinthella: Hyacinthella is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae (formerly the family Hyacinthaceae).  It is native to eastern and south-eastern Europe through to northern Iran, reaching as far south as Palestine.  Turkey is the main country in which species are found.

Walleye epidermal hyperplasia virus: Walleye epidermal hyperplasia virus is a retrovirus classified under, Epsilonretroviruses, a recent genus addition to the family of Retroviridae.  There are three genome sequenced and identified exogenous retroviruses of this genus which include two known types (WEHV-1 and WEHV-2) associated with walleye epidermal hyperplasia disease.  Both viral types are confirmed to be the causative agents of the neoplastic condition in the freshwater fish species, the North American Walleye "(Stizostedion vitreum)".  The specific association of retroviral infection with proliferative lesions in fish is based on the presence of retrovirus-like particles (observed via electron microscopy) and reverse transcriptase activity (using reverse transcriptase polymerase chain reaction techniques) from neoplastic tissue.  Although both virus types have been observed in lesions of diseased fish, each cell of the infected tissue is host to a specific virus.  Transmission studies have also shown that WEHV-2 has been the more proliferative agent of the condition as compared to WEHV-1.

Repetobasidiopsis: Repetobasidiopsis is a fungal genus of unknown familial placement in the order Polyporales.  It contains the crust fungus species Repetobasidiopsis grandispora.  The genus and species were first proposed in 2006, but two different herbaria were designated for the types of the two new species described in that publication, in contravention of the rules for describing new species.  The specific epithet "grandisporus" refers to the large-sized spores in comparison with the morphologically similar genus "Repetobasidiellum".  The generic name "Repetobasidiopsis" alludes to the proliferating, or repeating, basidia.  Two years later the genus was published validly.

Pereskia: Pereskia, as traditionally circumscribed, is a genus of 17 tropical species and varieties of cacti that do not look much like other types of cacti, having substantial leaves and thin stems.  They originate from the region between Brazil and Mexico.  Members of this genus are usually referred to as lemon vines, rose cacti or leaf cacti, though the latter also refers to the genus "Epiphyllum".  The genus is named after Nicolas-Claude Fabri de Peiresc, a 16th-century French botanist.

Paradisaea: The genus Paradisaea consists of seven species of birds-of-paradise (family Paradisaeidae).  The genus is found on the island of New Guinea as well as the nearby islands groups of the Aru Islands, D'Entrecasteaux Islands and West Papua Islands.  The species inhabit a range of forest types from sea level to mid-montane forests.  Several species have highly restricted distributions, and all species have disjunct distributions.  A 2009 study examining the mitochondrial DNA of the family found that the "Paradisaea" birds-of-paradise were in a clade with the genus "Cicinnurus".  It showed that the blue bird-of-paradise was a sister taxon to all the other species in this genus.

Luma chequen: Luma chequen (White Chilean Myrtle) is a species of flowering plant in the genus "Luma" in the family Myrtaceae, native to the central Andes mountains between Chile and Argentina, at latitudes located 30 to 41° South.  Synonyms include "Eugenia chequen" Molina, "Myrtus chequen" (Molina) Spreng., and "Luma gayana" (Barn.)  Burret.  Common names in Spanish include Chequén, Huillipeta, and Arrayán Blanco (White Myrtle).

Myrtus: Myrtus, with the common name myrtle, is a genus of flowering plants in the family Myrtaceae, described by Linnaeus in 1753.
