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.
Cyathea fuliginosa Cyathea fuliginosa is a species of tree fern native to the islands of Luzon, Biliran and Mindanao in the Philippines, where it grows in forest at an altitude of 640-2400 m. This tree fern has an erect trunk up to 5 m tall or more. Fronds are bi- or tripinnate and 1-3 m in length. The stipe is warty and may also (or instead) have short spines as well as many scattered scales towards the base. These scales are dark, glossy and have fragile edges. Sori occur near the fertile pinnule midvein and are protected by firm, dark indusia.
