Question: Which genus has more species, Malephora or Kirengeshoma?

full_context: Document 1: Chaenomeles: Chaenomeles is a genus of three species of deciduous spiny shrubs, usually 1–3 m tall, in the family Rosaceae. They are native to Japan, Korea, China, Bhutan, and Burma. (Burmese: ချဉ်စော်ကား ) These plants are related to the quince ("Cydonia oblonga") and the Chinese quince ("Pseudocydonia sinensis"), differing in the serrated leaves that lack fuzz, and in the flowers, borne in clusters, having deciduous sepals and styles that are connate at the base.
Document 2: Melasphaerula: Melasphaerula is a genus of flowering plants in the family Iridaceae, first described as a genus in 1803. There is only one known species, Melasphaerula graminea, native to Namibia and the Cape Province in South Africa.
Document 3: Paulownia: Paulownia is a genus of six to 17 species (depending on taxonomic authority) of flowering plants in the family Paulowniaceae, related to and sometimes included in the Scrophulariaceae. They are present in much of China, south to northern Laos and Vietnam and are long cultivated elsewhere in eastern Asia, notably in Japan and Korea. They are deciduous trees 12 – tall, with large, heart-shaped leaves 15–40 cm across, arranged in opposite pairs on the stem. The flowers are produced in early spring on panicles 10–30 cm long, with a tubular purple corolla resembling a foxglove flower. The fruit is a dry capsule, containing thousands of minute seeds.
Document 4: Schizophragma: Schizophragma (hydrangea vine) is a genus of four species of flowering plants in the family Hydrangeaceae, native to moist woodland in Asia, from the Himalayas east to Taiwan and Japan. They are vigorous, hardy deciduous lianas growing to 12 m , cultivated for their showy flower heads borne in mid- to late summer, resembling those of the related lacecap hydrangeas.
Document 5: Sphaeralcea: Sphaeralcea is a genus of flowering plants in the mallow family (Malvaceae). There are about 40-60 species, including annuals, perennials, and shrubs. Most originate in the drier regions of North America, with some known from South America. They are commonly known as globemallows, globe mallows, or falsemallows. The name of the genus is derived from the Greek words σφαῖρα ("sphaira"), meaning "sphere," and αλκεα ("alkea"), meaning "mallow."
Document 6: Titanopsis: Titanopsis is a genus of about 10 species of succulent plants of the family Aizoaceae, indigenous to the arid regions of South Africa and Namibia.
Document 7: Delosperma: Delosperma ('delos'=evident, 'sperma'=seed) is a genus of around 100 species of succulent plants, formerly included in "Mesembryanthemum" in the family Aizoaceae. The family is common in southern and eastern Africa.
Document 8: Dichroa: Dichroa is a genus of 12 species of flowering plants in the family Hydrangeaceae, native to eastern and southeastern Asia. They are deciduous shrubs growing to 1-3 m tall, with their leaves arranged in opposite pairs. The flowers are produced in a broad inflorescence similar to that of the related genus "Hydrangea". The fruit is a glossy metallic purple-blue berry.
Document 9: Malephora: Malephora is a genus of succulent plants in the ice plant family. There are 13 to 17 species in the genus, many of which are known commonly as mesembs. They are native to Africa.
Document 10: Stapeliae: The genera of plants within the tribe Stapeliae are all to varying degrees stem succulents. Many of the species resemble cacti, though are not closely related, as an example of convergent evolution. The stems are often angular, mostly four-angled in cross-section, but in some species there are six or more, with some species of "Hoodia" having more than thirty angles. In size they vary from less than 2.5 cm/1" in length to over 2 m/6" tall. The leaves are in most species reduced to rudiments, sometimes hardened and thorn-like, arranged on bumps or tubercles on the angles. Some species, however, still have recognisable leaves, most notably the Indian species "Frerea indica", and some members of "Tridentea". Stapeliads are most abundant in warm, dry climates. In Africa, there are two separate regions where Stapeliads have most diversified: northeast Africa, and Southern Africa. Several species are endemic to the small island of Socotra off the Horn of Africa. The Arabian Peninsula, and most specifically the country of Yemen, contain another concentration of species. Several more are found in the drier parts of Pakistan, Afghanistan, India, Nepal, and Myanmar. A single species, "Caralluma europea" is found in Europe, in the very southern part of the Iberian peninsula. Stapeliads are often regarded as a climax group within the family because of their often structurally complex flowers. Certain aspects of these reproductive parts mirror the pollination systems in the Orchid family and represent a case of parallel evolution though both groups are quite unrelated and have developed similar, though not identical means to achieve the ultimate goal of pollination and therefore reproduction. Most stapeliads use flies as pollinators, that are attracted to odours resembling dung or rotting meat, emanating from the flowers. Many of the flowers also bear some physical resemblance to rotting animal carcasses, leading to their popular name of Carrion Flowers. However, not all stapeliads smell bad, or attract flies. Some species use beetles, bees, wasps, butterflies or moths as pollinators. Stapeliad flowers range in size from mere millimetres in species of "Echidnopsis" and "Pseudolithos" to those of "Stapelia gigantea" that can reach 40 cm/16" in diameter, and are some the largest of flowers to be found on any species of succulent.
Document 11: Hydrangea: Hydrangea ( ; common names hydrangea or hortensia) is a genus of 70–75 species of flowering plants native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest species diversity is in eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters tall, but some are small trees, and others lianas reaching up to 30 m by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous.
Document 12: Kirengeshoma: Kirengeshoma is a genus containing two species of plants in the hydrangea family. Both are clump-forming perennials native to Eastern Asia, with sycamore-like palmate leaves and nodding, waxy yellow flowers on slender stalks, growing in shady environments. They are grown as garden plants in temperate regions of the world.
Document 13: Malephora crocea: Malephora crocea is a species of flowering plant in the ice plant family known by the common name coppery mesemb and red ice plant. It is native to Africa and it is grown in many other places as an ornamental plant and a groundcover. In California and Baja California this is an introduced species and often a noxious weed in coastal habitat such as beaches and bluffs. It is planted along highways in California and in Arizona it is utilized in landscaping for its low water needs and tolerance of sun. It has been recommended as a groundcover in areas prone to wildfire in southern California due to its low flammability.
Document 14: Deinanthe: Deinanthe is a genus consisting of a few species of rare herbaceous-habit rhizomatous plants found in the mountain woodlands of East Asia, ranging from China to Japan. They are handsome clump-forming perennials good for shade, woodland and rock gardens. These attractive deciduous plants have relatively large "fishtail" leaves (cleft at the apex). Deinanthes grow at a slow rate to be bushy and shrub-like, 2ft tall and wide. The leaves attain 3 to 4 inches in length,being deep green, roughly textured, deep veined, cordate at their bases and with serrate margins. The shoots emerge from stout, knobby rhizomes. Leaves are easily damaged in direct sun exposure. Flowering occurs in late summer to early fall. The delicate, waxy, nodding cup-shaped flowers in rich to pale purple-blue, rose or white, are borne in loose terminal clusters. Resembling gargantuan fertile hydrangea flowers, with numerous yellowish to pale blue anthers, they are occasionally accompanied by sterile flowers, as in the lacecap hydrangeas. Roots and leaves are edible.
Document 15: Lithops: Lithops is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words λίθος ("lithos"), meaning "stone," and ὄψ ("ops"), meaning "face," referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones. The formation of the name from the Greek "-ops" means that even a single plant is called a Lithops.
