Question: In between Iresine and Echinacea which genus contains 20 to 25 species?
Related documents: [0]  [DOC] Iresine is a genus of flowering plants in the amaranth family, Amaranthaceae. It contains 20 to 25 species, all of which are native to the American tropics. The generic name is derived from the Greek word εριος ("erios"), meaning "wooly", referring to the trichome-covered flowers. Bloodleaf is a common name for those species that have colored foliage, and these are often cultivated as ornamental plants. Some species are additives to versions of the hallucinogenic drink Ayahuasca. [END] 
[1]  [DOC] Echinacea is a genus, or group of herbaceous flowering plants in the daisy family. The "Echinacea" genus has nine species, which are commonly called purple coneflowers. They are found only in eastern and central North America, where they are found growing in moist to dry prairies and open wooded areas. They have large, showy heads of composite flowers, blooming from early to late summer. The generic name is derived from the Greek word ἐχῖνος ("ekhinos"), meaning "hedgehog," due to the spiny central disk. These flowering plants and their parts have different uses. Some species are cultivated in gardens for their showy flowers. "Echinacea purpurea" is used in folk medicine. Two of the species, "E. tennesseensis" and "E. laevigata", are listed in the United States as endangered species. [END]
