The Cronquist system is a taxonomic classification system of flowering plants.
 It was developed by Arthur Cronquist in a series of monographs and texts, including "The Evolution and Classification of Flowering Plants" (1968; 2nd edition, 1988) and "An Integrated System of Classification of Flowering Plants" (1981) ("see" Bibliography).
Pycnophallium is a genus-level name in the butterfly family Lycaenidae.
 The genus name was erected by the Dutch lepidopterist Lambertus Johannes Toxopeus in 1929.
 He included two Oriental species under this name: "Pycnophallium roxus" Godart and "Pycnophallium elna" Hewitson.
 These species had previously been treated as species in the genera "Lycaena" or "Castalius" until Hans Fruhstorfer erected "Caleta" in 1922.
 Although "Caleta" in the wide sense has not been fully revised since Fruhstorfer erected it, , 1992, made an authoritative classification of Oriental polyommatine genera.
 Hirowatari did not recognise "Pycnophallium" as a valid genus, but retained nine species, including "roxus" and "elna" in "Caleta".
Inferae is an artificial group used in the identification of plants based on Bentham and Hooker's classification.
 Bentham and Hooker published an excellent classification in three volumes in between 1862 and 1883.
 As a natural system of classification, it does not show evolutionary relationship between plants but still is a useful and popular system of classification based on a dichotomous key especially for the flowering plant groups (angiosperms.)
 It is the most popular system of classification based on key characteristics enabling taxonomic students to quickly identify plant groups based only on physical characteristics.
 However, it is not a scientific group and is used for identification purposes only based on similar plant characteristics.
 Under the system Inferae are a group of plants based on an artificial and non scientific series.
 The group Inferae are Gamopetalae and dicotyledons.
 The group comprises;
Hippocrepis is a genus of ornamental plants in the family Fabaceae.
Gamopetalae is an artificial group used in the identification of plants based on Bentham and Hooker's classification system.
 George Bentham and Joseph Dalton Hooker published an excellent classification in three volumes between 1862 and 1883.

 Under the system Gamopetalae is a Sub Class and comprises;
Bicarpellatae is an artificial group used in the identification of plants based on Bentham and Hooker's classification system.

Heteromerae is an artificial group used in the identification of plants based on Bentham and Hooker classification system.
 Bentham and Hooker published an excellent classification in three volumes between 1862 and 1883.

 It is the most popular system of classification especially for the flowering plant groups (angiosperms) based on key characteristics.
 This enables taxonomic students to quickly identify plant groups based only on physical characteristics.
 Under the system Heteromerae is a Sub Class, Series ii and it is often not used.
 The series comprises;
Eryngium is a genus of flowering plants in the family Apiaceae.
 There are about 250 species.
 The genus has a cosmopolitan distribution, with the center of diversity in South America.
 Common names include eryngo and amethyst sea holly (though the genus is not related to the true hollies, "Ilex").
The dingy skipper ("Erynnis tages") is a butterfly of the Hesperiidae family.
 It ranges from Europe across Asia Minor and Central Asia to the Amur region.
 "Erynnis tages" favours open grassy habitats up to 2,000 metres above sea level.
 The insect flies in two generations from May–June and July–August but in northern regions and at the high altitudes, there is only a single generation.
 Larval host plants in Europe are "Eryngium", "Lotus", "Coronilla", "Medicago", "Hippocrepis" etc.
Polyommatus corydonius, the false chalkhill blue, is a butterfly of the Lycaenidae family.
 The species is distributed in Caucasus, Transcaucasia, north-eastern Turkey, and north-western Iran.
 It inhabits a wide variety of grasslands and woodlands.
 In Armenia it occurs from 1200 to 2000 m above sea level.
 The known larval host plants of the species in Turkey is Hippocrepis comosa, in the Caucasus - Coronilla varia.

Question: Are both Eryngium and Hippocrepis genus-level classification of plants?
Answer: yes
