Question: Which genus has more accepted species Browningia or Aristotelia?

Context paragraphs:
Aeschynanthus: Aeschynanthus is a genus of about 150 species of evergreen subtropical plants in the family Gesneriaceae.  They are usually trailing epiphytes with brightly colored flowers that are pollinated by sunbirds.  The genus name comes from a contraction of "aischuno" (to be ashamed) and "anthos" (flower).  The common name for some species is "lipstick plant", which comes from the appearance of the developing buds.  A full list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.

Suksdorfia: Suksdorfia is a genus in the family Saxifragaceae.  There are only two accepted species: "Suksdorfia ranunculifolia" and "Suksdorfia violacea".  Asa Gray named the genus "Suksdorfia" after Wilhelm Nikolaus Suksdorf, a mostly self-taught German botanist who came to the United States at age eight and found the species "S. violacea" in the northwestern United States.  "S. violacea" is the type species for this genus.

Tuarangia: Tuarangia is an extinct genus of early bivalve, the only genus in the extinct family Tuarangiidae and order Tuarangiida.  The genus is known solely from Middle to Late Cambrian fossils found in Europe and New Zealand.  The genus currently contains two accepted species, Tuarangia gravgaerdensis and the type species Tuarangia paparua.

Aralia: Aralia , or spikenard, is a genus of the family Araliaceae, consisting of 68 accepted species of deciduous or evergreen trees, shrubs, and rhizomatous herbaceous perennials.  The genus is native to Asia and the Americas, with most species occurring in mountain woodlands.  "Aralia" plants vary in size, with some herbaceous species only reaching 50 cm tall, while some are trees growing to 20 m tall.

Pojetaia: Pojetaia is an extinct genus of early bivalves, one of two genera in the extinct family Fordillidae.  The genus is known solely from Early to Middle Cambrian fossils found in North America, Greenland, Europe, North Africa, Asia, and Australia.  The genus currently contains two accepted species, Pojetaia runnegari, the type species, and Pojetaia sarhroensis, though up to seven species have been proposed.  The genera Buluniella, Jellia, and Oryzoconcha are all considered synonyms of "Pojetaia".

Browningia: Browningia is a genus of cacti, comprising 11 accepted and 3 unresolved species.  It is named for Webster E Browning (1869-1942), director of the Instituto Inglés, Santiago,Chile.

Bistorta: Bistorta is a genus of flowering plants in the Polygonaceae family with only one accepted species, "Bistorta sherei" H. Ohba & Akiyama (2002).  It has been supported as a separate clade by molecular phylogenetic analysis.  A number of species that were once assigned to "Bistorta" are now either treated as synonyms of species in the genus "Persicaria", or currently remain unresolved.

Aristotelia (plant): Aristotelia is a genus with 18 species, of tree in the family Elaeocarpaceae.  It is named in honor of the Greek philosopher Aristoteles.

List of Narcissus species: This list of "Narcissus" species shows the accepted species names within the genus "Narcissus" ( ), which are predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family.  Various common names including daffodil, narcissus, and jonquil are used to describe all or some members of the genus.  The list of species is arranged by subgenus and section.  Estimates of the number of species in "Narcissus" have varied widely, from anywhere between 16 and nearly 160, even in the modern era.  Linnaeus originally included six species in 1753.

Gesneria: Gesneria is a genus of approximately 50 species in the flowering plant family Gesneriaceae.  Except for two or three odd South American species, all are native to islands of the Caribbean.  The genus is classified in the tribe Gesnerieae along with the genera "Bellonia", "Pheidonocarpa", and "Rhytidophyllum".  "Gesneria" species are usually woody shrubs or subshrubs, and (with the closely related "Rhytidophyllum") are unusual in the family in having alternately (rather than decussately) arranged leaves.  A complete list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.
