Question: Which plant has more species, Achimenes or Bearberry?

full_context: Document 1: Chlidanthus: Chlidanthus is a genus that consists of 10 species of tender bulbs from tropical South America, mostly natives to the Andes. The botanical name comes from the Greek, meaning "delicate flower". The plants have large spherical bulbs with gray-green, strap-shaped leaves 30cm long arising from the base. In late spring to early summer, clusters of 3-4 large, strong citrus-scented fragrant, funnel-shaped flowers 10-13cm long held terminally on stalks 25cm high, colored in yellow, pink or red.
Document 2: Bearberry: Bearberries are three species of dwarf shrubs in the genus "Arctostaphylos". Unlike the other species of "Arctostaphylos" (see manzanita), they are adapted to Arctic and Subarctic climates, and have a circumpolar distribution in northern North America, Asia and Europe, one with a small highly disjunctive population in Central America.
Document 3: Iresine: Iresine is a genus of flowering plants in the amaranth family, Amaranthaceae. It contains 20 to 25 species, all of which are native to the American tropics. The generic name is derived from the Greek word εριος ("erios"), meaning "wooly", referring to the trichome-covered flowers. Bloodleaf is a common name for those species that have colored foliage, and these are often cultivated as ornamental plants. Some species are additives to versions of the hallucinogenic drink Ayahuasca.
Document 4: Achimenes grandiflora: Achimenes grandiflora is a plant species in the genus "Achimenes", family Gesneriaceae. It is native to Mexico and Central America, growing in mountainous regions from Chihuahua to Nicaragua. It is cultivated as an ornamental in other places because of its showy purple flowers.
Document 5: Berberis aristata: Berberis aristata, also known as Indian barberry, "chutro" or tree turmeric, is a shrub belonging to the family Berberidaceae and the genus "Berberis". The genus comprises approximately 450-500 species of deciduous evergreen shrubs and is found in the temperate and sub-tropical regions of Asia, Europe, and America. "B. aristata" is native to the Himalayas in India and in Nepal. It is also naturally found in the wet zone of Sri Lanka.
Document 6: Arctostaphylos rubra: Arctostaphylos rubra is a species of flowering plant in the heath family and the genus "Arctostaphylos", the manzanitas and bearberries. Common names include red fruit bearberry, alpine bearberry, arctic bearberry, red manzanita, and ravenberry. It is native to Eurasia and northern North America from Alaska through most of Canada to Greenland. There is also one population in the contiguous United States, located in the Absaroka Mountains of Wyoming.
Document 7: Justicia (plant): Justicia is a genus of flowering plants in the family Acanthaceae. There are 658 species with a further 611 species as yet unresolved by Kew. They are native to tropical to warm temperate regions of the Americas, India and Africa. Common names include water-willow and shrimp plant, the latter from the inflorescences, which resemble a shrimp in some species. The generic name honours Scottish horticulturist James Justice (1698–1763). They are closely related to "Pachystachys".
Document 8: Cotoneaster dammeri: Cotoneaster dammeri, the bearberry cotoneaster, is a species of flowering plant in the genus "Cotoneaster", belonging to the Rosaceae family, native to central and southern China (Gansu, Guizhou, Hubei, Sichuan, Tibet and Yunnan) and naturalized in Europe.
Document 9: Ceropegia: Ceropegia is a genus of plants within the family Apocynaceae, native to Africa, southern Asia, and Australia. It was named by Carl Linnaeus, who first described this genus in volume 1 of his "Species plantarum", which appeared in 1753. Linnaeus thought that the flowers looked like a fountain of wax. From this the scientific name was derived: ‘"keros"’ meaning wax and ‘"pege"’ meaning fountain (Pooley, 1998). They have many common names including lantern flower, parasol flower, parachute flower, bushman’s pipe, string of hearts, snake creeper, wine-glass vine, rosary vine, and necklace vine.
Document 10: Arctostaphylos uva-ursi: Arctostaphylos uva-ursi is a plant species of the genus "Arctostaphylos" (manzanita). Its common names include kinnikinnick and pinemat manzanita, and it is one of several related species referred to as bearberry.
Document 11: Cinnamon bear: The cinnamon bear ("Ursus americanus cinnamomum") is both a color phase and subspecies of the American black bear, native to central and western areas of the United States and Canada. Established populations are found in Colorado, New Mexico, Utah, Idaho, Montana, Washington, Manitoba Minnesota, Wisconsin, Wyoming, California, Alberta, and British Columbia. They also have been seen in Pennsylvania and New York. The most striking difference between a cinnamon bear and any other black bear is its brown or red-brown fur, reminiscent of cinnamon. The subspecies was given the designation because the lighter color phase is more common there than in other areas.
Document 12: Arceuthobium abietinum: Arceuthobium abietinum is a species of dwarf mistletoe known as fir dwarf mistletoe. It is native to western North America from Washington to New Mexico to northern Mexico, where it lives in coniferous forests as a parasite on various species of fir, particularly white fir, giant fir, and red fir. This is a small shrub which is visible as a network of scaly yellowish stems extending above the bark of its host tree. Most of the mistletoe is located inside the host tree, attached to it via haustoria, which tap the tree for water and nutrients. The leaves of the mistletoe are reduced to knobby scales on its surface. It is dioecious, with male and female mistletoe plants producing spikes of staminate and pistillate flowers, respectively. The fruit is a sticky berry a few millimeters long which explodes to disperse the seeds it contains several meters away from the parent plant and its host tree.
Document 13: Achimenes: Achimenes is a genus of about 25 species of tropical and subtropical rhizomatous perennial herbs in the flowering plant family Gesneriaceae. They have a multitude of common names such as magic flowers, widow's tears, Cupid's bower, or hot water plant.
Document 14: Talinum: Talinum is a genus of herbaceous succulent plants in the family Talinaceae (formerly in the family Portulacaceae) whose common names include fameflower and flameflower. Several species bear edible leaves, and "Talinum fruticosum" is widely grown in tropical regions as a leaf vegetable. "Talinum paniculatum" is grown as an ornamental plant.
Document 15: 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.
