Its generally against the law in the US to take anything from the public land or the wild, and poaching will be prosecuted if the offender is caught. Which makes sense in MOST cases....where it doesn't make sense is if there is a stand of usable plant material on public land that is slated to be mowed down or have the lot cleared for development. Those plants should be able to be 'rescued'. But the law does not read that way here...if you get caught pulling plants off the roadside here you can get fined.
It may well be different in other countries, they may be more lax. I think Indonesia tries to be stricter, I don;t know about Phillipines.
The real violation of the law with other countries usually occurs when the CITES regulations are violated. Some individual plants are protected because they are rare in the wild and are not allowed to be harvested, sold, and shipped internationally.
I would agree with the ID's above, the 3rd, the Techteria, I have one species of that which I don;t know the species name...no one seems to know here even fern people. It popped up as a volunteer in a container once and stayed around.
