Which is a type of fern, Cibotium or Ecballium?
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"). It gets its unusual name from the fact that, when ripe, it squirts a stream of mucilaginous liquid containing its seeds, which can be seen with the naked eye. It is thus considered to have rapid plant movement.
Cibotium cumingii Cibotium cumingii is a species of tree fern, of the genus "Cibotium". It is named after the 19th century collector, Hugh Cuming. Its apex and young fronds are covered with reddish hairs. It can be found growing in open forest or in hilly areas in the Philippines and in Taiwan.
