Dont think it is terrestrial. Closest thing it looks to a terresrial plant is a maybe hosta (due to the shape of its leaf, but the stem structure is wrong) or possibly a baby climber called Actinidia kolomikta. Could be in the Viburnum family too.
But i have never came across any plants that look like that and i work in a garden nursery which sells terrestrial plants. Knowing my luck some cleaver cookie will proove me wrong tho.
Looks kind of like a Radican Sword to me. If it is then I don't think they usually grow under water. I've seen them by ponds and such in the water but not fully submerged.
Hi, i asked a few of my work mates today what the plant was and the closest they thought of is:
It might not be that specific one, but its in the same family of plants. They also said that it is more likely to be a house plant if it is terrestrial. and likely to be a tripical plant due to the structure of the stem and leaves. (Exactly what i thought )So there's the verdict from the professional horticulturalists at tendercare! (place i work)
Enjoy
EDIT... Oh and i think the english name is piece lilly???
it looks alot like the cane we have growing in the wood, japanese cane weed or somthing similar, its non aquatic extremely eveasive when used terrestrialy, the roots are the same as is the structure.
ill try and find a proper name for it, but if it is the same stuff thats in our wood i would burn it so it doesnt take over where ever you dump it
its not a piece lilly look a the leaves of it in the tank they have 5 "veins" running up from the stalk where as the piece lilly only has one. and the stem formation is diffrent to a lillys as wel lillys tend to grow more in arosette
