Question: Are both Saritaea and Hornbeam considered the genus of plants?

Context paragraphs:
Horkelia: Horkelia is a genus of plants in the rose family.  It includes several species of plants known commonly as horkelias.  These are flowering plants closely related to the cinquefoils ("Potentilla") and sometimes considered part of the same genus.  There are nineteen species found in western North America, especially California.  "Horkelia" was named for German scientist Johann Horkel.

Canarina: Canarina is a genus of flowering plants within the family Campanulaceae.  They are herbaceous perennial vines with bell-shaped flowers.  The best known species is "C. canariensis" from the laurel forests of the Canary Islands which is grown as an ornamental plant.  "Canarina canariensis" is one of a group of unrelated Canarian plants that appear to be adapted for bird pollination, including the members of the genera "Isoplexis" and "Lotus".  It was once thought that the original pollinators of these plants were sunbirds which had become extinct on the Canary Islands, explaining why some of these species are rare and considered endangered (Vogel 1954; Vogel et al. 1984; Olesen 1985; Valido et al. 2004).  However more recent work has shown that these plants are adequately pollinated by non-specialist flower visiting birds, particularly the Canary Islands chiffchaff ("Phylloscopus canariensis") and the Canary Island spectacled warbler ("Sylvia conspicillata orbitalis") (Olesen 1985; Ollerton et al. 2008), and in fact show some specific adaptations to infrequent pollination by these birds, such as extended flower lifespans (Ollerton et al. 2008), and a hexose-dominated sugar ratio of the nectar (Dupont et al. 2004).

Smilax sect. Nemexia: Smilax" sect.  "Nemexia is a section of plants in the family Smilacaceae.  It consists of the herbaceous plants within the genus "Smilax".  "Smilax" species fall into two groups with distinctive morphologies: one group has woody perennial stems with thorns and a vining habit, while the other group has herbaceous stems that die back to the ground each winter.  "S." sect.  "Nemexia" is the taxon that comprises the herbaceous species.  In the past it was often a genus of its own under the name Nemexia and taxonomists still need further study of the species of "Smilax" to determine its proper rank.  However the widely accepted taxonomic system of the "Flora of North America" does not recognize "Nemexia", nor does the AP-site.  Thus "Nemexia" is not currently considered an accepted genus taxon by most plant taxonomists.

Lloydieae: The Lloydieae were a tribe of monocotyledon perennial, herbaceous mainly bulbous flowering plants in the Liliaceae (Lily) family.  The tribe was generally considered monogeric, being represented by the single genus "Lloydia".  But since that genus has at various times and is now considered to be part of the genus "Gagea", and therefore in the "Lilieae" tribe, it was sometimes listed with both genera.  Furthermore many authorities place "Gagea" into a separate tribe, Tulipeae.  It has also historically been considered to be a subtribe of the Lilieae.  In 2013, Kim "et al." proposed splitting off "Gagea" from the rest of Tulipeae by resurrecting the tribe Lloydieae.

Nepenthes: Nepenthes ( ), also known as tropical pitcher plants, is a genus of carnivorous plants in the monotypic family Nepenthaceae.  The genus comprises roughly 150 species, and numerous natural and many cultivated hybrids.  They are mostly liana-forming plants of the Old World tropics, ranging from South China, Indonesia, Malaysia and the Philippines; westward to Madagascar (two species) and the Seychelles (one); southward to Australia (three) and New Caledonia (one); and northward to India (one) and Sri Lanka (one).  The greatest diversity occurs on Borneo, Sumatra, and the Philippines, with many endemic species.  Many are plants of hot, humid, lowland areas, but the majority are tropical montane plants, receiving warm days but cool to cold, humid nights year round.  A few are considered tropical alpine, with cool days and nights near freezing.  The name "monkey cups" refers to the fact that monkeys have been observed drinking rainwater from these plants.

List of Utricularia species: There are around 233 species in the genus "Utricularia", belonging to the Bladderwort family (Lentibulariaceae).  It is the largest genus of carnivorous plants and has a worldwide distribution, being absent only from Antarctica and the oceanic islands.  This genus was considered to have 250 species until Peter Taylor reduced the number to 214 in his exhaustive study, "The genus Utricularia - a taxonomic monograph", published by HMSO (1989).  Taylor's classification is generally accepted, though his division of the genus in two subgenera was soon seen as obsolete.  Molecular genetic studies have mostly confirmed Taylor's sections with some modifications (Jobson et al., 2003), but reinstalled the division of the genus in three subgenera.  This list follows the subgeneric classification "sensu" Müller & Borsch (2005), updated with new information in Müller et al. (2006).

Carduus: Carduus is a genus of flowering plants in the aster family, Asteraceae, and the tribe Cynareae, one of two genera considered to be true thistles, the other being "Cirsium".  Plants of the genus are known commonly as plumeless thistles.  They are native to Eurasia and Africa, and several are known elsewhere as introduced species.  This genus is noted for its disproportionately high number of noxious weeds compared to other flowering plant genera.

Hornbeam: Hornbeams are hardwood trees in the flowering plant genus "Carpinus" in the birch family Betulaceae.  The 30–40 species occur across much of the temperate regions of the northern hemisphere.

Stylidium: Stylidium (also known as triggerplants or trigger plants) is a genus of dicotyledonous plants that belong to the family Stylidiaceae.  The genus name "Stylidium" is derived from the Greek "στύλος" or "stylos" (column or pillar), which refers to the distinctive reproductive structure that its flowers possess.  Pollination is achieved through the use of the sensitive "trigger", which comprises the male and female reproductive organs fused into a floral column that snaps forward quickly in response to touch, harmlessly covering the insect in pollen.  Most of the approximately 300 species are only found in Australia, making it the fifth largest genus in that country.  Triggerplants are considered to be protocarnivorous or carnivorous because the glandular trichomes that cover the scape and flower can trap, kill, and digest small insects with protease enzymes produced by the plant.

Saritaea: Saritaea is a monotypic genus in the trumpet-vine family, Bignoniaceae.  The sole species, Saritaea magnifica, glowvine, is native to Colombia and Ecuador.  The stems are almost round in cross-section, and are marked with longitudinal stripes.  The 10 cm leaves have 2 leaflets and a further 2 leaflet-like appendages at the base of the leaf stalk, plus a tendril at the tip.  The leaves are smooth and leathery.  The plant is a very spectacular flowering, evergreen tropical climber.  The large heads of showy rosy mauve to purple coloured, bell-shaped flowers 8 cm long with hairy yellow throat, borne at the end of the branches often display all year-round .  When in flower it is regarded as one of the outstanding climbers of the world.  Their nectar is collected by the male bees of the tropical genus "Euglossa", which pollinate the flowers by brushing against the pollen and transferring it.  The fruit is a long flattened capsule containing 2-winged seeds.
