Euodia is a plant genus in the Rutaceae family.
 "Euodia" is sometimes misspelled as "Evodia".
 The species now included in the genus "Tetradium" were previously included in "Euodia", and may be commonly referred to as euodia.
Tetradium is a genus of nine species of trees in the family Rutaceae, occurring in temperate to tropical east Asia.
 In older books, the genus was often included in the related genus "Euodia" (sometimes written, ""Evodia"" from latin spelling), but that genus is now restricted to tropical species.
 In cultivation in English-speaking countries, they are known as Euodia, Evodia, or Bee bee tree.
Mucuna holtonii is a species of plant in the bean family, which is pollinated by bats. Bats are able to detect if the flowers have nectar using echolocation.
 After an initial bat visit during which nectar is removed, the petals are arranged in a different manner (altering the shape of the flower).
 As a result, the unique "echo fingerprint" of petal arrangement informs the bat whether nectar is present or absent.
 This trait appears to have coevolved with bats.
Mucuna is a genus of around 100 accepted species of climbing lianas (vines) and shrubs of the family Fabaceae and typically found in tropical woodlands.
Tetradium daniellii, the bee-bee tree or Korean evodia, is a species of flowering plant in the Rutaceae family.
Mucuna bennettii, commonly known as New-Guinea creeper or scarlet jade vine, is a species of flowering plant in the family Fabaceae, that is native to Papua New Guinea.
Tetradium ruticarpum is a tree that comes from China and Korea.
 It was previously classified in the genus "Euodia" as "Euodia ruticarpa".
 The fruit is usually used, denoted sometimes as "fructus".
 It has a strong bitter taste, and is used in traditional Chinese medicine (TCM) and is a recognized herb in Kampo.
 Both the former genus name and the species name are often misspelled, and the plant usually appears in sources dealing with traditional Chinese medicine as ""Evodia(e) rutaecarpa"".
