Google Scholar is a freely accessible web search engine that indexes the full text or metadata of scholarly literature across an array of publishing formats and disciplines.
 Released in beta in November 2004, the Google Scholar index includes most peer-reviewed online academic journals and books, conference papers, theses and dissertations, preprints, abstracts, technical reports, and other scholarly literature, including court opinions and patents.
 While Google does not publish the size of Google Scholar's database, third-party researchers estimated it to contain roughly 160 million documents as of May 2014 and an earlier statistical estimate published in PLOS ONE using a Mark and recapture method estimated approximately 80-90% coverage of all articles published in English with an estimate of 100 million.
 This estimate also determined how many documents were freely available on the web.
Larentiinae moths contain roughly 5,800 species and occur mostly in the temperate regions of the world.
 They are generally considered a subfamily of the geometer moth family (Geometridae) and divided into a few large or good-sized tribes, and numerous very small or even monotypic ones which might not always be valid.
 Well-known members are the "pug moths" of the Eupitheciini and the "carpets", mainly of the Cidariini and Xanthorhoini.
The docks and sorrels, genus Rumex L., are a genus of about 200 species of annual, biennial, and perennial herbs in the buckwheat family Polygonaceae.
Rumex hydrolapathum Huds.
 (great water dock; water dock; giant water dock) is a species of perennial herbaceous plants in the genus "Rumex" native to fens and freshwater banks of Europe and Western Asia.
 It is the tallest species in the genus, with flowering stems attaining a height of up to 2 m .
 It is one of the small number of decaploid organisms, containing two hundred individual chromosomes.
Thalictrum sparsiflorum is a species of flowering plant in the buttercup family known by the common name fewflower meadow-rue.
 It is native to northwestern North America and parts of northeastern Asia.
 It grows in moist habitat, such as streambanks and forest understory.
 It is a perennial herb producing erect stems up to about a meter in maximum height.
 The leaves have compound blades divided into a few or many segments which are borne on long, slender petioles.
 The blades are usually finely hairy and glandular.
 The inflorescence is a leafy panicle of flowers.
 Unlike some other "Thalictrum" species which are dioecious, this species has bisexual flowers.
 Each has a calyx of five greenish sepals, and up to 20 light-colored dangling stamens tipped with large anthers.
 The flowers develop into compressed, beaked fruits.
The East baray (Khmer: បារាយណ៍ខាងកើត ), or Yashodharatataka, is a now-dry baray, or artificial body of water, at Angkor, Cambodia, oriented east-west and located just east of the walled city Angkor Thom.
 It was built around the year 900 AD during the reign of King Yasovarman.
 Fed by the Siem Reap River flowing down from the Kulen Hills, it was the second-largest baray in the Angkor region, measuring roughly 7.5 by 1.8 kilometers and holding over 50 million cubic meters of water.
 Stones bearing inscriptions that mark the construction of the baray have been found at all four of its corners.
 The labour and organization necessary for its construction were staggering: Its dikes contain roughly 8 million cubic meters of fill.
Thalictrum ( ) is a genus of 120-200 species of herbaceous perennial flowering plants in the Ranunculaceae (buttercup) family native mostly to temperate regions.
 Meadow-rue is a common name for plants in this genus.
The Vatican Museums (Italian: "Musei Vaticani" ) are Christian and art museums located within the city boundaries of the Vatican City.
 They display works from the immense collection amassed by Popes throughout the centuries including some of the most renowned classical sculptures and most important masterpieces of Renaissance art in the world.
 The museums contain roughly 70,000 works, of which 20,000 are on display, and currently employ 640 people who work in 40 different administrative, scholarly, and restoration departments.
In mathematics and computer science, a primality certificate or primality proof is a succinct, formal proof that a number is prime.
 Primality certificates allow the primality of a number to be rapidly checked without having to run an expensive or unreliable primality test.
 By "succinct", we usually mean that we wish for the proof to be at most polynomially larger than the number of digits in the number itself (for example, if the number has "b" bits, the proof might contain roughly "b" bits).
The Carajás Mine is the largest iron ore mine in the world.
 It is located in the municipality of Parauapebas, state of Pará in the Carajás Mountains of Northern Brazil.
 The mine is operated as an open-pit mine, and is estimated to contain roughly 7.2 billion tons of iron ore, plus gold, manganese, copper, and nickel.

Question: Do the genuses Thalictrum and Rumex contain roughly the same number of species?
Answer: yes
