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.
Asplenium azoricum Asplenium azoricum is a fern from hybrid origin of the Aspleniaceae family, descendent of the Macaronesian ancestral fern "Asplenium anceps". It lives exclusively in the Azores, that is a strict endemic Azorean fern. Its fronds are coriaceous like plastic and its rachis is very thick, dark garnet color and brilliance. A typical feature of this fern, which it shares with all the descendants of "A. anceps", is the existence of a small atrium at the base of the medium and lower pinnae geared towards the apex of the frond with one or two sori in its underside.
