Which has more species, Utricularia or Alphitonia?
Utricularia Utricularia, commonly and collectively called the bladderworts, is a genus of carnivorous plants consisting of approximately 233 species (precise counts differ based on classification opinions; one recent publication lists 215 species). They occur in fresh water and wet soil as terrestrial or aquatic species across every continent except Antarctica. "Utricularia" are cultivated for their flowers, which are often compared with those of snapdragons and orchids, especially amongst carnivorous plant enthusiasts.
Utricularia corynephora Utricularia corynephora is a small, probably perennial, carnivorous plant that belongs to the genus "Utricularia". Its native distribution includes Burma and Thailand and is only known from the type specimen from the southern peninsula of Burma and from a collection on the adjacent peninsula in Thailand. "U. corynephora" grows as a lithophyte on wet granite rock faces at altitudes from 180 m to 750 m . It was originally described by Peter Taylor in 1986.
