Which genus has more species, Petunia or Kigelia?
Petunia Petunia is genus of 35 species of flowering plants of South American origin, closely related to tobacco, cape gooseberries, tomatoes, deadly nightshades, potatoes and chili peppers in the same family, Solanaceae. The popular flower of the same name derived its epithet from the French, which took the word "petun", meaning "tobacco," from a Tupi–Guarani language. An annual, most of the varieties seen in gardens are hybrids ("P." × "atkinsiana", also known as "P." × "hybrida").
Syzygium guineense Syzygium guineense (Bambara: "Kokisa" ) is a leafy forest tree of the Myrtaceae family, found in many parts of Africa both wild and domesticated. Both its fruits and leaves are edible; the pulp and the fruit skin are sucked and the seed discarded. It is sometimes called "waterberry", but this may also refer to other species of "Syzygium".
