Which has more species, Evolvulus or Centradenia?
Centradenia Centradenia is a genus of 4-5 species of tropical evergreen perennials or subshrubs, native to Central America and Mexico.
Sphaerodactylus Sphaerodactylus is a genus of geckos from the Americas that are distinguished from other Gekkota by their small size, by their round, rather than vertical, eye pupils, and by each digit terminating in a single, round adhesive pad or scale, from which their name ("Sphaero" = round, "dactylus" = finger) is derived. All species in this genus are rather small, but two species, "S. ariasae" and "S. parthenopion", are tiny, and – with a snout-vent length of about 1.6 cm —the smallest reptiles in the world.
