Question: Which genus has more species, Geissorhiza or Stenocarpus?

full_context: Document 1: Iris germanica: Iris x germanica is the accepted name for a species of flowering plants in the family "Iridaceae" commonly known as the bearded iris or the German iris. It is one of a group of hybrid origin.
Document 2: Hypoxis: Hypoxis is a genus of flowering plants belonging to the family Hypoxidaceae. The genus has an "almost cosmopolitan" distribution, occurring in Africa, the Americas, Asia, and Australia. Europe lacks native species. Most species are in the Southern Hemisphere, especially in southern Africa. Common names for the genus include star-grass, star lily, yellow stars, African potato, and stars. The genus is the largest of the Hypoxidaceae family and has its centre of variation in South Africa, where it occurs in open undisturbed grasslands. The name "Hypoxis" was taken over by Linnaeus in 1759 from a name coined by Paul Reneaulme in 1611 for a superficially similar species of "Gagea" and meaning "a little sour", referring to the taste of that plant's leaves.
Document 3: Cunonia: 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.
Document 4: Podocarpus: Podocarpus ( ) is a genus of conifers, the most numerous and widely distributed of the podocarp family, Podocarpaceae. "Podocarpus" are evergreen shrubs or trees, usually from 1 to tall, known to reach 40 m at times. The cones have two to five fused cone scales which form a fleshy, berry-like, brightly coloured receptacle at maturity. The fleshy cones attract birds which then eat the cones and disperse the seeds in their droppings. There are approximately 97 to 107 species in the genus depending on the circumscription of the species.
Document 5: Stenocarpus: Stenocarpus is a genus of about 25 species known to science, of woody trees or shrubs, constituting part of the plant family Proteaceae.
Document 6: Leptospermum: 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.
Document 7: Gladiolus: Gladiolus (from Latin, the diminutive of "gladius", a sword,) is a genus of perennial cormous flowering plants in the iris family (Iridaceae).
Document 8: Phebalium stenophyllum: Phebalium stenophyllum, commonly known as Narrow-leafed Phebalium, is a shrub which is endemic to Victoria and New South Wales in Australia. It grows to between 1 and 1.5 metres in height and produces clusters of starry yellow flowers in the spring.
Document 9: Pteleocarpa: Pteleocarpa is a genus of flowering plants. The only member of the genus is the western Malesian tree Pteleocarpa lamponga. It has had a varied systematic history and has been placed in the families Icacinaceae, Cardiopteridaceae, Boraginaceae, and others. It has long been regarded as enigmatic. For example, its winged fruit is quite odd within the family Boraginaceae, where it was usually placed in the 2000s. The family name Pteleocarpaceae had been used, but was not validly published until 2011, when the required description was published in Kew Bulletin. A morphological study of "Pteleocarpa" was published in 2014. Also in 2014, a molecular phylogenetic study of the lamiids (a.k.a. Garryidae) sampled "Pteleocarpa" and resolved it as sister to Gelsemiaceae. Both genera of Gelsemiaceae ("Gelsemium" and "Mostuea") were sampled and this result had maximum statistical support in three different methods of cladistic analysis. The authors of that study recommended that "Pteleocarpa" be included in Gelsemiaceae. This was formally done in 2014 by altering the description of the family to accommodate it. In the APG IV system published in 2016, "Pteleocarpa" is included in Gelsemiaceae.
Document 10: Geissorhiza: Geissorhiza is a genus of about 80 species of deciduous perennial flowering plants in the iris family first described as a genus in 1803. The entire genus is endemic to Cape Province of western South Africa. The genus name is derived from the Greek words "geisson", meaning "tile", and "rhizon", meaning "root".
Document 11: Ceratopetalum: Ceratopetalum is a genus of nine species of shrub and tree in the family Cunoniaceae. They are found along the eastern coast of Australia and extend north to New Guinea. Two Australian species are among the best known, one being "C. apetalum" or coachwood, renowned as a timber tree, and "C. gummiferum", the New South Wales Christmas bush, so named as it flowers in December.
Document 12: Sparaxis: Sparaxis (harlequin flower) is a genus in the family Iridaceae with about 13 species endemic to Cape Province, South Africa.
Document 13: Iris (plant): Iris is a genus of about 260–300, species of flowering plants with showy flowers. It takes its name from the Greek word for a rainbow, which is also the name for the Greek goddess of the rainbow, Iris. Some authors state that the name refers to the wide variety of flower colors found among the many species. As well as being the scientific name, "iris" is also very widely used as a common name for all "Iris" species, as well as some belonging to other closely related genera. A common name for some species is 'flags', while the plants of the subgenus "Scorpiris" are widely known as 'junos', particularly in horticulture. It is a popular garden flower.
Document 14: Dimorphotheca: Dimorphotheca is a genus of plants in the sunflower family, native to Africa and Australia. is one of eight genera of the Calenduleae, with a centre of diversity in Southern Africa. Some species can hybridize with "Osteospermum", and crosses are sold as cultivated ornamentals. The name ""Dimorphotheca"" comes from the Greek "Dis" "Morphe" and "Theka", meaning "two shaped fruit", referring to the dimorphic cypselae, a trait inherent to members of the Calenduleae. Plants of this genus usually have bisexual flowers.
Document 15: Adenanthos: Adenanthos is a genus of Australian native shrubs in the flowering plant family Proteaceae. Variable in habit and leaf shape, it is the only genus in the family where solitary flowers are the norm. It was discovered in 1791, and formally published by Jacques Labillardière in 1805. The type species is "Adenanthos cuneatus", and 33 species are recognised. The genus is placed in subfamily Proteoideae, and is held to be most closely related to several South African genera.
