Angiopteris Evecta (Giant Ferns)Angiopteris Evecta (Giant Ferns) is a Registered Property, Province of Camarines Norte located at Santa Elena, Camarines Norte, Region V.
Some of the largest ferns on our planet. Arising from an odd looking globular mass are massive fiddle heads. These gradually unfurl into fronds of epic proportions. The record for frond size goes to Angiopteris evecta. An individual growing in Java produced fronds that were 29 feet 6 inches (9 meters) long. Amazingly enough, these fronds are capable of moving up or down depending on the weather.
Such movements are no small feat for a frond of that size. It is all thanks to an area of the petiole known as the pulvinus. The pulvini are swollen regions at the base of the petiole that expand or contract based on water pressure within.
Angiopteris evecta produces the largest pulvini of any plant in the world.
