Flemingia is a genus of flowering plants in the legume family Fabaceae.
 It is native to Asia and the species are distributed in Bhutan, Burma, China, India; Indonesia, Laos, Malaysia, Nepal, Pakistan, Papua New Guinea, Philippines, Sri Lanka, Taiwan, Thailand and Vietnam.
 The genus was founded in 1812.
 The number of known species is ambiguous due to taxonomic problems; and is usually enumerated as more than 30.
 Burma and China have the highest record of "Flemingia" species with 16 each, followed by India (with 15 species), Thailand (11 species), Laos (10 species), Vietnam (8 species), Bhutan (1 species) and Nepal (5 species).
Phoxinus is a genus of freshwater fish in the family Cyprinidae of order Cypriniformes.
 The type species is "Phoxinus phoxinus".
 The other species in this genus are also commonly known as minnows.
 The name "minnow" was what early English fisherman used to describe "small and insignificant".
 The genus "Phoxinus" is found throughout Eurasia, and includes 21 known species.
 Previously, members of the North American genus "Chrosomus" were also believed to form part of this genus.
Lactarius is a genus of mushroom-producing, ectomycorrhizal fungi, containing several edible species.
 The species of the genus, commonly known as milk-caps, are characterized by the milky fluid ("latex") they exude when cut or damaged.
 Like the closely related genus "Russula", their flesh has a distinctive brittle consistency.
 It is a large genus with roughly 450 known species, mainly distributed in the Northern hemisphere.
 Recently, the genus "Lactifluus" has been separated from "Lactarius" based on molecular phylogenetic evidence.
Bolitoglossa is a genus of lungless salamanders, also called mushroom-tongued salamanders tropical climbing salamanders or web-footed salamanders, in the family Plethodontidae.
 Their range is between northern Mexico through Central America to Colombia, Venezuela, Ecuador, Peru, northeastern Brazil, and central Bolivia.
 Neotropical salamanders of the "Bolitoglossa" genus make up the largest genus in the order Caudata, consisting of approximately one-fifth of all known species of salamanders.
 Adult salamanders range anywhere from 45mm to 200mm in length depending on their specific species.
 They are notorious for their ability to project their tongue at prey items, as indicated from their name.
 They are also known for their webbed feet, having significantly more webbing than any other species outside their genus with the exception of the cave-dwelling Mexican bolitoglossine "Chiropterotriton magnipes".
 Although webbed feet are a common characteristic of these salamanders, only about half of the species in this genus contain webbed feet.
Lavandula (common name lavender) is a genus of 47 known species of flowering plants in the mint family, Lamiaceae.
 It is native to the Old World and is found from Cape Verde and the Canary Islands, Europe across to northern and eastern Africa, the Mediterranean, southwest Asia to southeast India.
 Many members of the genus are cultivated extensively in temperate climates as ornamental plants for garden and landscape use, for use as culinary herbs, and also commercially for the extraction of essential oils.
 The most widely cultivated species, "Lavandula angustifolia", is often referred to as lavender, and there is a color named for the shade of the flowers of this species.
Ascaridia is the name of a genus of parasitic nematodes. Members of the genus are primarily intestinal parasites of birds.
 There are three well known species, namely, "A. galli" found mostly in chicken, "A. dissimilis" in turkeys, and "A. columbae" in pigeons. Lesser known species such as "A. hermaphrodita", "A. sergiomeirai", "A. ornata", "A. nicobarensis" and "A. platyceri" are found in parrots.
Termitaphididae, occasionally called termite bugs, is a small tropicopolitan family of true bugs placed in the superfamily Aradoidea.
 Typically members of Termitaphididae are small, being an average of 2 mm -4 mm , and flattened with laminae extending out from each body segment giving a round scale like appearance.
 Currently the family contains two genera and twelve known species.
 Members of Termitaphididae are inquilines lodging in the nests of host species of termite families Termitidae and Rhinotermitidae.
 Though considered a separate family in Aradoidea it has been suggested by Drs David Grimaldi and Michael Engel in 2008 that Termataphididae may in fact be highly derived members of Aradidae.
 Of the thirteen known species one "Termitaphis circumvallata" belongs to the monotypic genus "Termitaphis" and four of the remaining eleven species in "Termitaradus" are extinct, having only been found in amber.
 The living species are found worldwide in the tropical regions of Central and South America, Africa, Asia, and Australia.
Ageratum ( ), (whiteweed in the USA), is a genus of 40 to 60 tropical and warm temperate flowering annuals and perennials from the family Asteraceae, tribe Eupatorieae.
 Most species are native to Central America and Mexico but four are native to the United States.
Arcobacter is a genus of Gram-negative, spiral-shaped bacteria in the epsilonproteobacteria class.
 It shows an unusually wide range of habitats, and some species can be human and animal pathogens.
 Species of the genus "Arcobacter" are found in both animal and environmental sources, making it unique among the epsilonproteobacteria.
 This genus currently consists of five species: "A. butzleri", "A. cryaerophilus", "A. skirrowii", "A. nitrofigilis", and "A. sulfidicus", although several other potential novel species have recently been described from varying environments.
 Three of these five known species are pathogenic.
 Members of this genus were first isolated in 1977 from aborted bovine fetuses.
 They are aerotolerant, "Campylobacter"-like organisms, previously classified as "Campylobacter".
 The "Arcobacter" genus, in fact, was created as recently as 1992.
 Although they are similar to this other genus, "Arcobacter" species can grow at lower temperatures than "Campylobacter", as well as in the air, which "Campylobacter" cannot.
Moniezia a genus of tapeworms that are parasitic in mammals, including sheep, goat and cattle.
 It comprises four known species such as "M. expansa", "M. benedeni", "M. autumnalis" and "M. baeri". "
M. expansa" is the most well known species within the genus because of its high prevalence.
 Members of the genus are among the largest cestodes reaching up to 10 m in length.
 They inhabit the small intestine of mammalian host.
 Their life cycle is indirect requiring intermediate host, which are oribatid mites.
 They are characterized by the presence of interproglottid glands.

Question: Which genus has more known species, Ageratum or Lavandula?
Answer: Ageratum
