Which is a type of fern, Cibotium or Ecballium?
Cibotium: Cibotium (from the Greek "kibootion", meaning chest or box) is a genus of 11 species of tropical tree fern—subject to much confusion and revision—distributed fairly narrowly in Hawaiʻ i (four species, plus a hybrid, collectively known as hāpuʻ u), Southeast Asia (five species), and the cloud forests of Central America and Mexico (two species). Ecballium: Ecballium is a genus of flowering plants in the family Cucurbitaceae containing a single species, Ecballium elaterium, also called the squirting cucumber or exploding cucumber (but not to be confused with "Cyclanthera explodens").
