Question: Which genus has more species, Cyananthus or Polypodium?

full_context: Document 1: Athyrium: Athyrium (lady-fern) is a genus of about 180 species of terrestrial ferns, with a cosmopolitan distribution. It is placed in the family Athyriaceae, in the order Polypodiales.
Document 2: Blechnum: Blechnum (hard fern) is a genus of between 150–220 species of ferns with a cosmopolitan distribution, in the family Blechnaceae in the eupolypods II clade of the order Polypodiales. By far the greatest species diversity is in tropical regions of the Southern Hemisphere, with only a few species reaching cool temperate latitudes in the Southern Hemisphere (notably "B. penna-marina", south to Cape Horn, Chile, the southernmost fern in the world) and Northern Hemisphere (notably "B. spicant", north to Iceland and northern Norway).
Document 3: Cyclamen purpurascens: Cyclamen purpurascens (Alpine, European or purple cyclamen) is a species of flowering plant in the genus "Cyclamen" of the family Primulaceae, native to central Europe, northern Italy, and Slovenia. It is a tuberous perennial with (usually) variegated leaves, and deep pink flowers in summer.
Document 4: Polypodium appalachianum: Polypodium appalachianum is a fern species native to eastern North America. Sometimes called the Appalachian polypody or Appalachian rockcap fern, it is very similar in appearance to "Polypodium virginianum". For years, "P. virginianum" -- long considered a variety of the British "Polypodium vulgare" -- was recognized as having cryptic races, with diploid, triploid, and tetraploid representatives. Since the triploid specimens bore abortive spores, it was apparently the hybrid between the diploid and tetraploid groups. In 1991, it was resolved that the type of "P. virginianum" was the tetraploid series, and that it is an allotetraploid species of hybrid origin, with the diploid species as one parent. The diploid species was then named "P. appalachianum". The other parent of "P. virginianum" was found to be "Polypodium sibiricum". The tetraploid of hybrid derivation tolerates warmer climates than either parent.
Document 5: Corydalis flexuosa: Corydalis flexuosa is a species of flowering plant in the genus "Corydalis", of the Papaveraceae family. It is a shade-loving perennial originating in woodland and mountainous areas of China. Growing to 30 cm , in spring it produces masses of bright blue tubular flowers with a white throat. It is summer dormant, meaning that the foliage dies down in summer.
Document 6: Phlebodium: Phlebodium is a small genus of two to four species of ferns, native to tropical and subtropical regions of the Americas. The genus is closely related to "Polypodium", and the species were formerly included in that genus.
Document 7: Cyananthus: Cyananthus is a genus that consists of about 30 species of annual or mostly perennial herbs from high mountains of Central and East Asia. They are little Himalayan plants not higher than 4in. The name comes from the "Greek" for blue flowers. Leaves are usually small and simple, sometimes narrowing to base, tooth-lobed at summit. In August to September, the plants bear showy of bright purplish-blue, yellow or white, funnel to bell-shaped, 5-lobed flowers 1in in diameter with stamens free from the corolla and hairy throat. The flowers are borne singly on stalks. They always lose the aerial parts during the coldest months, and as spring begins, stems and leaves quickly start to reproduce.
Document 8: Polystichum proliferum: Polystichum proliferum, commonly known as mother shield fern is an Australian endemic fern. The genus name Polystichum is derived from Greek "poly" - many, and "stichos -" rows referring to the many rows of sori. The species name is derived from Latin, "Proli" – offspring and "fer -" bearing referring to the proliferous buds, a prominent feature of the species.
Document 9: Strobilanthes: Strobilanthes is a genus of about 350 species of flowering plants in the family Acanthaceae, mostly native to tropical Asia and Madagascar, but with a few species extending north into temperate regions of Asia. Many species are cultivated for their 2-lipped, hooded flowers in shades of blue, pink, white and purple. Most are frost-tender and require protection in frost-prone areas.
Document 10: Polypodium: Polypodium is a genus of 75–100 species of true ferns, widely distributed throughout the world, with the highest species diversity in the tropics. The name is derived from Ancient Greek "poly" (πολύ) "many" + "podion" (πόδιον) "little foot", on account of the foot-like appearance of the rhizome and its branches. They are commonly called polypody or rockcap fern, but for many species unique vernacular names exist.
Document 11: 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 12: Polystichum: Polystichum is a genus of about 260 species of ferns with a cosmopolitan distribution. The highest diversity is in eastern Asia, with about 120 species in China alone; the region from Mexico to Brazil has nearly 100 additional species; Africa (17 species), North America (15 species), and Europe (5 species) have much lower diversity. Polystichum species are terrestrial or rock-dwelling ferns of warm-temperate and montane-tropical regions (a few species grow in alpine regions).
Document 13: Callianthemum: Callianthemum is a genus that consists of 24 species of little rhizomatous herbs from high mountains in Europe, Central Asia and East Asia. The botanical name comes from the Greek, which means beautiful flower. The plants are low-growing, ornamental perennials and are lovely to rock garden. Leaves are small and radical. Flowers are showy daisy-like, 1.5in in diameter, with 5-15 white or rose-color petals and nectaries at the base. Blooming in spring.
Document 14: Caulophyllum: Caulophyllum is a small genus of perennial herbs in the family Berberidaceae. It is native to eastern Asia and eastern North America. These plants are distinctive spring wildflowers, which grow in moist, rich woodland, it is known for its large triple-compound leaf, and large blue, berry-like fruits. Unlike many spring wildflowers, it is not an ephemeral plant and persists throughout much of the summer. Common names for plants in this genus include Blue Cohosh, Squaw Root, and Papoose Root. As hinted at by its common names, this plant is well known as an alternative medicine for inducing childbirth and menstrual flow; it is also considered a poisonous plant.
Document 15: Pulsatilla vernalis: Pulsatilla vernalis (spring pasqueflower, arctic violet, lady of the snows) is a species of flowering plant in the family Ranunculaceae, native to mountainous habitats in Europe. Growing to 10 cm high and wide, it is a semi-evergreen perennial with hairy, divided leaves. In early spring it bears anemone-like flowers which are up to 6 cm in diameter, white flushed with violet on the outer surface of the petals, and prominent yellow stamens.
ground_truth: Polypodium
