Question: Which is considered a genus level classification, Apera or Gunnera manicata?

Context paragraphs:
Gunnera manicata: Gunnera manicata, known as Brazilian giant-rhubarb giant rhubarb, or dinosaur food, is a species of flowering plant in the Gunneraceae family from Brazil.

Northwest Oregon Conference: The Northwest Oregon Conference (NWOC) is a 5A level classification that falls under the Oregon School Activities Association or the OSAA.  The conference was created in 2006 when the OSAA restructured its conference system, expanding from 4 levels to 6.  Schools at the 5A level had previously competed at the 4A or 3A level.

Hygrophila (plant): Hygrophila, commonly known as swampweeds, is a genus of flowering plants in the acanthus family, Acanthaceae.  There are about 80 to 100 species, of which many are aquatic plants.  The genus is distributed across the tropical and subtropical world.  It is one of only two genera in its family that contains aquatic plants, the other being "Justicia".  The genus is treated in the tribe "Hygrophileae", which is noted as being in need of revision at the genus level, meaning the current taxonomic boundaries of "Hygrophila" are likely to change in the future.

Apera: Apera is a small genus of annual grasses, known commonly as silkybent grass or windgrass.  They are native to Europe, North Africa and parts of Asia but have been introduced and naturalized in much of North and South America. United States Department of Agriculture Plants Profile

Rhabdognathus: Rhabdognathus is an extinct genus of dyrosaurid crocodylomorph.  It is known from rocks dating to the Paleocene epoch from western Africa, and specimens dating back to the Maastrichtian era were identified in 2008.  It was named by Swinton in 1930 for a lower jaw fragment from Nigeria.  The type species is "Rhabdognathus rarus".  Stéphane Jouve subsequently assessed "R. rarus" as indeterminate at the species level, but not at the genus level, and thus dubious.  Two skulls which were assigned to the genus "Rhabdognathus" but which could not be shown to be identical to "R. rarus" were given new species: "R. aslerensis" and "R. keiniensis", both from Mali.  The genus formerly contained the species "Rhabdognathus compressus", which was reassigned to "Congosaurus compressus" after analysis of the lower jaw of a specimen found that it was more similar to that of the species "Congosaurus bequaerti".  "Rhabdognathus" is believed to be the closest relative to the extinct "Atlantosuchus".

Sirodotia: Sirodotia Kylin (1912) is a freshwater red alga which was described by Kylin in 1912.  The family Batrachospermaceae belongs to the order Batrachospermales and has six well known genera namely Batrachospermum Roth (1797), Kumanoa Entwisle et al. (2009), Sirodotia Kylin (1912), Nothocladus Skuja (1934), Tuomeya Harvey (1938) and Sheathia Salomaki and M.L.Vis in Salomaki et al., (2014). The morphology of the gametophyte of Batrachospermum, Sirodotia, Tuomeya, and Nothocladus are more are less similar to each other.  Necchi and Entwisle (1990) proposed to delimit them from Generic level to section level of genus Batrachospermum Sheathia was the member of genus Batrachospermum and recently rose to generic level).  Later phylogenetic studies revealed a distinctive genus level of the above with full support in bootstrap analysis (Vis et al., 1998) and Sirodotia has been raised to generic level.

Trioceros: Trioceros is a genus of lizards in the family Chamaeleonidae.  "Trioceros" was previously considered a subgenus of the genus "Chamaeleo" until 2009 when it was elevated to full genus level.

Apera spica-venti: Apera spica-venti, the loose silky-bent or common windgrass, is an annual or biannual plant in the genus "Apera".  It belongs to the Poaceae family.

List of Tortricidae genera: This is a taxonomy of the moth family Tortricidae down to genus level.  This classification is up-to-date to 2008, taking information from World Catalogue of the Tortricidae and taxonomic changes made in 2007.

Direct-controlled municipality: A direct-controlled municipality is the highest level classification for cities used by unitary state, with status equal to that of the provinces in the respective countries.  A direct-controlled municipality is similar to, but not the same as, a Federal district, a common designation in various countries for a municipality that is not part of any state, and which usually hosts some governmental functions.  Usually direct-controlled municipality are under central governments control with limited power.
