Question: Which has more species Leucothoe or Cyperus?
Context: Cyperus articulatus is an aromatic species of sedge known by the common names jointed flatsedge and priprioca.  It has also been known as Guinea rush or adrue.  It grows as a perennial herb.  It grows in water or near it in rivers, streams, lakes, and swamps with a hyperhydrate (emergent aquatic) or possibly tenagophyte (submerged juvenile and terrestrial adult) growth pattern.  It is widespread across tropical and subtropical regions in Africa, southern Asia, northern Australia, the southeastern United States, the West Indies, and Latin America.  While it is closely related to highly invasive sedges such as purple nut sedge ("Cyperus rotundus"), priprioca is less prolific and competitive than its relative. 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). Cyperus is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions. Leucothoe is a genus of about 50 species of flowering plants in the family Ericaceae, native to Asia, the Americas and Madagascar. Cyperus distans, also known as slender cyperus, is a species of sedge native to tropical and subtropical wetlands in sub-Saharan Africa, Asia (India, Indochina, China, Indonesia, Philippines, etc.), Madagascar, New Guinea, Australia, Latin America (from Mexico to Argentina), the West Indies, the southeastern United States (Florida, Georgia, North Carolina) and various oceanic islands. Cyperus rotundus (coco-grass, Java grass, nut grass, purple nut sedge or purple nutsedge, red nut sedge, Khmer kravanh chruk) is a species of sedge (Cyperaceae) native to Africa, southern and central Europe (north to France and Austria), and southern Asia.  The word "cyperus" derives from the Greek κύπερος , "kyperos", and "rotundus" is from Latin, meaning "round".  The earliest attested form of the word "cyperus" is the Mycenaean Greek 𐀓𐀞𐀫 , "ku-pa-ro", written in <a href="Linear%20B">Linear B</a> syllabic script. Cyperus elegans, the royal flatsedge, is a sedge species in the genus "Cyperus" from Central and South America. Leucothoe incisa is an amphipod in the family Leucothoidae.  It grows up to 7 mm long, and is whitish in colour, but a yellowish green along the back, with intensely red eyes.  It lives at depths of up to 60 m along the Atlantic coast of Europe from the Mediterranean Sea to Scotland, and in the North Sea.  It is part of group of sibling species, together with "Leucothoe lilljeborgi" and "Leucothoe occulta". Cyperus bipartitus, commonly known as slender flatsedge, river cyperus, or the shining flatsedge, is a common species of sedge.  The name "slender flatsedge" also applies to "Cyperus gracilis". 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.
