Question: Which genus, Rubus or Cunonia, contains the largest number of individual species?
Context: An oak is a tree or shrub in the genus Quercus ( ; Latin "oak tree") of the beech family, Fagaceae.  There are approximately 600 extant species of oaks.  The common name "oak" also appears in the names of species in related genera, notably "Lithocarpus" (stone oaks), as well as in those of unrelated species such as "Grevillea robusta" (silky oaks) and the Casuarinaceae (she-oaks).  The genus "Quercus" is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa.  North America contains the largest number of oak species, with approximately 90 occurring in the United States, while Mexico has 160 species of which 109 are endemic.  The second greatest center of oak diversity is China, which contains approximately 100 species. Araripesuchus is an extinct genus of notosuchian crocodyliform that lived in Gondwana during the Cretaceous Period.  The genus includes at least five species found throughout Western Africa and South America.  The relationship of the individual species within this genus is hotly debated, specifically, the placement of Araripesuchus wegeneri.  "A. wegeneri" is a small bodied crocodyliform characterized by relatively elongate limbs, an upright gait, and marked heterodonty.  The tooth morphology, when combined with tooth wear and orientation, suggests that this animal may have been an omnivore or herbivore.  Additionally, the gracile limbs and their orientation imply that this was a terrestrial animal.  These features demonstrate that "Araripesuchus wegeneri" stands in stark contrast to its modern-day relatives, crocodiles and alligators. Rubus is a large and diverse genus of flowering plants in the rose family, Rosaceae, subfamily Rosoideae, with 250–700 species. The Be'er Sheva fringe-fingered lizard ("Acanthodactylus beershebensis") is a species of lizard in the Lacertidae family.  It is a member of the subgenus Lacertinae, and the tribe Acanthodactylus (spiny footed lizards).  Considered a separate species based on morphological distinction, and isolated location; it shares a large portion of its genetics with "Acanthodactylus pardalis" in this genus.  Many of the individual species under this genus are similar, but varying coloration explains why each species have been separated.  Like all "Acanthodactylus", the beershebensis lays eggs, varying from three to seven eggs at a time.  Adults vary in size from 17 to 20 centimeters, but can get much larger.  It is endemic to the loess scrublands of the Negev desert in Israel and the Palestinian Territories, a biodiversity hotspot. Leptospermum is a genus of shrubs and small trees in the myrtle family Myrtaceae commonly known as tea trees, although this name is sometimes also used for some species of "Melaleuca".  Most species are endemic to Australia, with the greatest diversity in the south of the continent but some are native to other parts of the world, including New Zealand and Southeast Asia.  Leptospermums all have five conspicuous petals and five groups of stamens which alternate with the petals.  There is a single style in the centre of the flower and the fruit is a woody capsule.  The first formal description of a leptospermum was published in 1776 by the German botanists Johann Reinhold Forster and his son Johann Georg Adam Forster, but an unambiguous definition of individual species in the genus was not achieved until 1979.  Leptospermums grow in a wide range of habitats but are most commonly found in moist, low-nutrient soils.  They have important uses in horticulture, in the production of honey and in floristry. This is a list of the mammal species recorded in Trinidad and Tobago.  These are the volant and terrestrial mammal species recorded for Trinidad and Tobago, and aquatic/marine species.  Of these 0 are critically endangered, 0 are endangered, 1 is vulnerable, and 0 are near-threatened.  However, it is very important to note that the populations of many of the game mammals as well as predatory mammals are locally threatened in Trinidad and Tobago due mainly to heavy hunting/poaching (see Hunting#Trinidad_and_Tobago) and habitat loss/fragmentation, with a number of species already having been extirpated on the island of Tobago.  This list is derived from the IUCN Red List which lists species of mammals and includes those mammals that have recently been classified as extinct (since 1500 AD).  The taxonomy and naming of the individual species is based on those used in existing Wikipedia articles as of 21 May 2007 and supplemented by the common names and taxonomy from the IUCN, Smithsonian Institution, or University of Michigan where no Wikipedia article was available. Sinocyclocheilus is a genus of freshwater fish in the family Cyprinidae endemic to China, where only found in Guangxi, Guizhou and Yunnan.  Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes (some are completely blind).  Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back (above the forehead), the function of which is unclear.  In contrast, the "Sinocyclocheilus" species that live aboveground, as well as a few found underground, show no clear cavefish adaptions.  They are relatively small fish reaching up to 23 cm in length.  The individual species have small ranges and populations, leading to the status of most of the evaluated species as threatened.  Many species populations in the genus have yet to be evaluated. Pancheria is a genus of shrubs and trees in the family Cunoniaceae.  It is to endemic to New Caledonia and contains 27 species.  Leaves or whorled (or opposite in Pancheria confusa), simple or pinnate.  The flowers are arranged in capitula, fruits are follicular.  The species are dioecious.  The genus is well diversified on ultramafic rocks and some species are nickel hyperaccumulators.  It is related to "Cunonia" and "Weinmannia".  It was named after Jean Armand Isidore Pancher. Cunonia is a genus of shrubs and trees in the family Cunoniaceae.  The genus has a disjunct distribution, with 24 species endemic to New Caledonia in the Pacific, and one species (Cunonia capensis) in Southern Africa.  Leaves are opposite, simple or pinnate with a margin entire to serrate.  Interpetiolar stipules are often conspicuous and generally enclose buds to form a spoon-like shape (hence the common name "Butterspoon Tree" for "Cunonia capensis").  Flowers are bisexual, white, red (pink to purple), or green, arranged in racemes.  The fruit is a capsule opening first around the base then vertically, seeds are winged. Myiodynastes is a genus of birds in the family Tyrannidae.  Created by Charles Lucien Bonaparte in 1857, the genus contains five species which are collectively referred to as "sulphur-bellied flycatchers"; that name is also given to one of the individual species in the genus.  The genus name "Myiodynastes" is a compound word composed from two Greek words: "muia", meaning "fly" and "dunastẽs", meaning "ruler".
