Can anyone identify this plant? Thanks in advance.

What a wonderfully interesting plant that is, rc. It has a growth habit, & leaf-shape, similar to my dracaena surculosa punctulata "Sierra Leone" but that plant looks more like a bamboo & has spotted leaves. At the moment I am racking my brain to try & remember if I have seen this plant before. Of course, we may not have it down here in Australia but I feel I have grown something like this many years ago.

Have you seen how the stems form?? Do they shoot up like a spear then grow the leaves when fully grown?? Has it ever flowered??? It does seem to be thriving in the conditions it is in which could give a clue as to what type of plant it is. Is it in direct or indirect light?? Could it be a type of schefflera or umbrella tree, which is indigenous to the Australian tropics?? They do look different when grown in a pot to those which we see in gardens around here. There are a few different schefflera species, too.

Another thought is that could it be an ornamental ficus elastica, which is a type of rubber tree. There is more than one type, apparently. Are the leaves brownish on the underside??

It does seem as though the plant you have is several plants all planted close together. The spindly stems are similar to those of both plants, I have mentioned, when grown in pots.
