Question: Which one is belonging to the genus of plants in the grass family, Ginseng or Cynodon?
Context: Deschampsia is a genus of plants in the grass family, commonly known as hair grass or tussock grass.  The genus is widespread across many countries. Polytrias is a genus of Asian, African, and Pacific Island plants in the grass family, commonly called Java grass Batiki bluegrass, Indian murainagrass, or toto grass.  The only known species is Polytrias indica, native to West Africa (from Senegal to Cameroon), Seychelles, the Indian Subcontinent, southern China, Southeast Asia, New Guinea, Fiji, and Micronesia.  It is also cultivated as a lawn grass in other tropical regions, and naturalized in scattered locations in tropical North and South America. Ampelodesmos is a genus of Mediterranean plants in the grass family, which is known by the common names stramma, Mauritania grass, rope grass, and dis grass.  It is classified in its own tribe Ampelodesmeae within the grass subfamily Pooideae. Ixophorus is a genus of Latin American plants in the grass family.  The only recognized species is Ixophorus unisetus.  Some authors have included one or two other species in the genus, such as "I. pringlei", but these have more recently been reduced to synonymy.  Common names for "I. unisetus" include crane grass, turkey grass, Honduras grass, Mexican grass, Central America grass, hático (Colombia), zacate blanco (El Salvador, Honduras, Mexico), and zacate chompipe (Nicaragua). Ginseng ( ) is any one of the species of slow-growing perennial plants with fleshy roots, belonging to the genus "Panax" of the family Araliaceae.  This article focuses on two species of the genus "Panax", named "Panax ginseng" and "Panax quinquefolius". Pseudoginsenoside F11 is a chemical natural product found in American ginseng ("Panax quinquefolius") but not in Asian ginseng ("Panax ginseng"), although it has similar properties to the Asian ginseng compound ginsenoside Rf.  The molecule is a triterpenoid saponin member of the dammarane family and contains a four-ring rigid skeleton.  Compounds in the ginsenoside family are found almost exclusively in plants of the "Panax" genus, which have long histories of use in traditional medicine; a wide variety of difficult-to-characterize biological effects have been reported for the compounds in isolation.  Pseudoginsenoside F11 and its derivatives are sometimes referred to as having an "ocotillol"-type skeleton structure. Panax notoginseng is a species of the genus "Panax", and it is most commonly referred to in English as notoginseng.  In Chinese it is called "tiánqī" (田七), tienchi ginseng, "sānqī" (三七) or "sanchi", three-seven root, and mountain plant.  "P. notoginseng" belongs to the same scientific genus as Asian ginseng.  In Latin, the word "panax" means "cure-all", and the family of ginseng plants is one of the best-known herbs. Festuca (fescue) is a genus of flowering plants belonging to the grass family, Poaceae (subfamily Pooideae).  They are evergreen or herbaceous perennial tufted grasses with a height range of 10 - and a cosmopolitan distribution, occurring on every continent except Antarctica.  The genus is closely related to ryegrass ("Lolium"), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly.  As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus "Festuca" into the genus "Lolium". Cynodon is a genus of plants in the grass family.  It is native to warm temperate to tropical regions of the Old World, as well as being cultivated and naturalized in the New World and on many oceanic islands. Panax pseudoginseng is a species of the genus "Panax".  Common names include Pseudoginseng, Nepal ginseng, and Himalayan ginseng.  Pseudoginseng belongs to the same scientific genus as ginseng.  In Latin, the word "panax" means "cure-all", and the family of ginseng plants is one of the best-known herbs.  "Panax pseudoginseng" is not an adaptogen like the better known "Panax" species, but it is famous as a hemostatic herb that both invigorates and builds blood.
Answer: Cynodon
