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.
Lycoperdon echinatum Lycoperdon echinatum, commonly known as the spiny puffball or the spring puffball, is a type of puffball mushroom in the genus "Lycoperdon". The saprobic species has been found in Africa, Europe, Central America, and North America, where it grows on soil in deciduous woods, glades, and pastures. It has been proposed that North American specimens be considered a separate species, "Lycoperdon americanum", but this suggestion has not been followed by most authors. Molecular analysis indicates that "L. echinatum" is closely related to the puffball genus "Handkea".
