question: Which genus of plants has more plants associated with it, Camassia or Acorus?
answer: Camassia
context: Title: Eriocaulon
  Passage: Eriocaulon is a genus of about 400 species commonly known as pipeworts, of monocotyledonous flowering plants in the family Eriocaulaceae.  The genus is widely distributed, with the centers of diversity for the group occurring in tropical regions, particularly southern Asia and the Americas.  A few species extend to temperate regions, with ca. 10 species in the United States, mostly in the southern states from California to Florida, and only two species in Canada; China has 35 species, also mostly southern.  Only one species ("E. aquaticum") occurs in Europe, where it is confined to the Atlantic Ocean coasts of Scotland and Ireland; this species also occurs in eastern North America and is thought to be a relatively recent natural colonist in Europe.  In the Americas, "Eriocaulon" is the only genus in its family that occurs north of Florida.  They tend to be associated with wet soils, many growing in shallow water, in wetlands, or in wet savannas like flatwoods.  In wet soils, their abundance appears to be related to water levels, fire frequency, and competition from other plants such as grasses.  Experiments have shown that they are weak competitors compared to many other wetland plant species.  Some species can persist as buried seeds during unfavorable conditions.  The scientific name is derived from Ancient Greek εριον, "erion", meaning 'wool', and καυλός, "caulos", meaning 'stalk'.
  Title: Camassia
  Passage: Camassia is a genus of plants in the asparagus family native to Canada and the United States.  Common names include camas, quamash, Indian hyacinth, camash, and wild hyacinth.
  Title: Acorus
  Passage: Acorus is a genus of monocot flowering plants.  This genus was once placed within the family Araceae (aroids), but more recent classifications place it in its own family Acoraceae and order Acorales, of which it is the sole genus of the oldest surviving line of monocots.  Some older studies indicated that it was placed in a lineage (the order Alismatales), that also includes aroids (Araceae), Tofieldiaceae, and several families of aquatic monocots (e.g., Alismataceae, Posidoniaceae).  However, modern phylogenetic studies demonstrate that "Acorus" is sister to all other monocots.  Common names include calamus and sweet flag.
  Title: Petuvirus
  Passage: Petuvirus is a genus of viruses, in the family Caulimoviridae.  Plants serve as natural hosts.  There is currently only one species in this genus: the type species Petunia vein clearing virus.  Diseases associated with this genus include: plants: chlorotic vein clearing, leaf malformation.
  Title: Nothocestrum breviflorum
  Passage: Nothocestrum breviflorum, commonly known as smallflower ʻ aiea, is a species of tree in the nightshade family, Solanaceae, that is endemic to the island of Hawaiʻ i.  It inhabits dry and mixed mesic forests at elevations of 180 - .  These forests are dominated by ʻ ōhiʻ a lehua ("Metrosideros polymorpha") and koa ("Acacia koa") or lama ("Diospyros sandwicensis"), while plants associated with smallflower ʻ aiea include wiliwili ("Erythrina sandwicensis") and uhiuhi ("Caesalpinia kavaiensis").  "N. breviflorum" reaches a height of 10 - .  It is threatened by habitat loss.  It is federally listed as an endangered species of the United States.  There are fewer than 50 individuals remaining.
  Title: Deathcamas
  Passage: Deathcamas or death camas refers to several species of flowering plant in the tribe Melanthieae.  The name alludes to the great similarity of appearance between these toxic plants, which were formerly classified together in the genus "Zigadenus", and the edible camases ("Camassia"), with which they also often share habitat.  Other common names for these plants include deadly zigadene, hog potato and mystery-grass.
