Which genus has more species Tetradium or Schlumbergera?
Tetradium 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.
Carathea Carathea is a genus of Tasmanian spiders within the Malkaridae family that was named and first described by R. J. Moran in 1986. The name comes from the Australian aboriginal word for "sister". The type species is "C. parawea". The features unique to spiders of this genus include a thin tip to the conductor (a sclerite in the male palpal bulb), the absence of "horns" on the carapace, and, in females, the internal genitalia are large and less compact, usually only containing three or four coils.
