Context_1 : Cyperus alternifolius, with the common names of umbrella papyrus, umbrella sedge or umbrella palm, is a grass-like plant in the very large genus "Cyperus" of the sedge family, Cyperaceae. Context_2 : Cyperus odoratus is a species of sedge known by the common names fragrant flatsedge and rusty flatsedge. This plant can be found in much of the tropical and warm temperate world, including South, Central, and North America, Southeast Asia, some Pacific Islands, Australia, New Guinea, Madagascar, and central Africa. It is a plant of wet, muddy areas, including disturbed and altered sites. This species is quite variable and may in fact be more than one species included under one name. In general this is an annual plant approaching half a meter in height on average but known to grow much taller. It usually has some long, thin leaves around the base. The inflorescence is made up of one to several cylindrical spikes attached at a common point. Each of the spikes bears a large number of flat, oval-shaped spikelets. Each spikelet is usually light brown to reddish-brown and has a few to over 20 flowers. Each flower is covered by a tough, flat bract with a visible midvein. The fruit is a flat achene less than two millimeters long. Context_3 : "Tulostoma" is a genus of over 100 species of fungi in the family Agaricaceae. Commonly known as stalked puffballs, the cosmopolitan genus consists of species which produce small fruit bodies, characterized by stalks inserted in a socket at the base of the spherical spore-sac opened by a small and apical mouth. The spore-sac contains gleba, a mixture of spores and associated cells; at maturity, the spores are released through one or more apical pores. "Tulostoma" species prefer xeric microhabitats, savannahs and deserts, and are saprobic—obtaining nutrients by decomposing roots, buried wood and other organic material of plant origin. Context_4 : Cyperus is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions. Context_5 : Cyperus elegans, the royal flatsedge, is a sedge species in the genus "Cyperus" from Central and South America. Context_6 : Dryopteris crassirhizoma is a fern species in the genus "Dryopteris". It is an element (Traditional: 貫眾, Simplified: 贯众) of the Yupingfeng Asian soup formulation derivative. Context_7 : Dryopteris cristata is a species of fern native to wetlands throughout the Northern Hemisphere. It is known as crested wood fern or crested buckler-fern. This plant is a tetraploid species of hybrid origin, one parent being "Dryopteris ludoviciana" and the other being the unknown, apparently extinct species, dubbed "Dryopteris semicristata", which is also one of the presumed parents of "Dryopteris carthusiana". "D. cristata" in turn is one of the parents of "Dryopteris clintoniana", another fern of hybrid origin. Context_8 : 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. Context_9 : Cyperus pseudothyrsiflorus is a plant species native to Nuevo León, New Mexico and Texas, a member of "Cyperus" subgenus "Cyperus". It occurs in cultivated fields and other disturbed areas at elevations of less than 1000 m (3400 feet). Context_10 : Cyperus giganteus (also known as piripiri) is a plant in the genus "Cyperus". Its native range extends from Jalisco in west-central Mexico as far south as Uruguay, and also grows on some islands in the Caribbean (Cuba, Hispaniola, Puerto Rico, Jamaica, and Trinidad). The species is sparingly naturalized in eastern Texas and southern Louisiana. fact_1 : 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. fact_2 : Cyperus is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions. Question: Which plant genus consists of more species, Dryopteris or Cyperus?
Output: Cyperus
