Question: Does Tillandsia or Polystichum have more species?

full_context: Document 1: 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 2: Dryopteris: Dryopteris , commonly called wood fern, male fern (referring in particular to "Dryopteris filix-mas"), or buckler fern, is a genus of about 250 species of ferns with distribution in Eastern Asia, the Americas, Europe, Africa, and the Pacific islands, with the highest species diversity in eastern Asia. Many of the species have stout, slowly creeping rootstocks that form a crown, with a vase-like ring of fronds. The sori are round, with a peltate indusium. The stipes have prominent scales.
Document 3: Guzmania: Guzmania (tufted airplant) is a genus of over 120 species of flowering plants in the botanical family Bromeliaceae, subfamily Tillandsioideae. They are mainly stemless, evergreen, epiphytic perennials native to Florida, the West Indies, southern Mexico, Central America, and northern and western South America. They are found at altitudes of up to 3500 m in the Andean rainforests.
Document 4: 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 5: Tillandsioideae: Tillandsioideae is a subfamily of plants in the bromeliad family Bromeliaceae. This group contains the fewest genera (9) but the greatest number of species (1,277). Most are epiphytic or lithophytic, growing in trees or on rocks where they absorb water and nutrients from the air. Spanish moss of the "Tillandsia" genus is a well-known variety. Bromeliads in the genera "Guzmania" and "Vriesia" are the more commonly cultivated members of this subfamily.
Document 6: Polystichum aleuticum: Polystichum aleuticum, the Aleutian holly fern or Aleutian shield fern, is an endangered species of the "Polystichum" genus and currently consisting of a small, vulnerable population endemic found only on Adak Island, Alaska, a remote island of the Aleutian Islands chain in the northern Pacific Ocean. In 1992, 112 specimens existed in the wild, and a recovery plan was implemented.
Document 7: 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 8: Tillandsia jalisco-monticola: Tillandsia jalisco-monticola is a species in the genus "Tillandsia". This species is endemic to the State of Jalisco, Mexico and its species name means "mountain dweller." Its small purple flowers are pollinated by hummingbirds and it has large red- to yellow-tinted bracts all year long.
Document 9: Tillandsia landbeckii: Tillandsia landbeckii is a species in the genus "Tillandsia". This species is endemic to Peru and Chile. It is one of the species of "Tillandsia" known as aerophytes, that grow on shifting desert soil rather than attached to other plants.
Document 10: 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 11: Tillandsia xerographica: Tillandsia xerographica is a species of bromeliad that is native to southern Mexico, El Salvador, Guatemala and Honduras. The name is derived from the Greek words ξηρός ("xeros"), meaning "dry," and γραφία ("graphia"), meaning "writing." It is included in "Tillandsia" subg. "Tillandsia".
Document 12: Polystichum imbricans: Polystichum imbricans is a species of fern known by the common names narrowleaf swordfern and imbricate sword fern. It is native to western North America from British Columbia to southern California, where it grows in rocky habitat in coastal and inland mountain ranges and foothills. This fern produces several erect linear or lance-shaped leaves up to 80 centimeters long. Each leaf is made up of many narrow, overlapping, sometimes twisting leaflets each 2 to 4 centimeters long. The leaflets have toothed edges. This fern readily forms hybrids, some of which are fertile and are considered separate species, such as "Polystichum californicum", its hybrid with "P. dudleyi".
Document 13: Tillandsia: Tillandsia is a genus of around 650 species of evergreen, perennial flowering plants in the family Bromeliaceae, native to the forests, mountains and deserts of Central and South America, the southern United States and the West Indies. They have naturally been established in diverse environments such as equatorial tropical rain forests, high elevation Andes mountains, rock dwelling (saxicolous) regions, and Louisiana swamps, such as Spanish Moss ("T. usneoides"), a species that grows atop tree limbs. Airplant is a common name for plants in this genus. Most "Tillandsia" species are epiphytes – i.e. they normally grow without soil while attached to other plants. Some are aerophytes or "air plants", which have no roots and grow on shifting desert soil. Generally, the thinner-leafed varieties grow in rainy areas and the thick-leafed varieties in areas more subject to drought. Most species absorb moisture and nutrients through the leaves from rain, dew, dust, decaying leaves and insect matter, aided by structures called trichomes.
Document 14: Nepenthes: Nepenthes ( ), also known as tropical pitcher plants, is a genus of carnivorous plants in the monotypic family Nepenthaceae. The genus comprises roughly 150 species, and numerous natural and many cultivated hybrids. They are mostly liana-forming plants of the Old World tropics, ranging from South China, Indonesia, Malaysia and the Philippines; westward to Madagascar (two species) and the Seychelles (one); southward to Australia (three) and New Caledonia (one); and northward to India (one) and Sri Lanka (one). The greatest diversity occurs on Borneo, Sumatra, and the Philippines, with many endemic species. Many are plants of hot, humid, lowland areas, but the majority are tropical montane plants, receiving warm days but cool to cold, humid nights year round. A few are considered tropical alpine, with cool days and nights near freezing. The name "monkey cups" refers to the fact that monkeys have been observed drinking rainwater from these plants.
Document 15: Pitcairnioideae: The Pitcairnioideae comprise the terrestrial subfamily of the bromeliads (Bromeliaceae) with over 1000 species in 16 genera. Unlike the many epiphytes and lithophytes which make up the rest of the family, with a few exceptions, all of the members of this subfamily are either terrestrial or saxicolous. Common to arid and high-altitude regions, this subfamily is considered to have the most ancient lineage, more closely resembling its grassy relatives than the exotic novelties represented in the other two subfamilies. The commonly cultivated genera from this group include "Dyckia", "Hechtia", "Pitcairnia", and "Puya".
