I'm leaning toward Chrysalidocarpus (Dypsis), but it's hard to tell until it gets more size to it. Usually though, Chrysalidocarpus develops yellowish and spotted trunks with more age. If no one else offers an ID, you might try the Palm forum. Oh, looks like you did already. Please report back if they can ID it there.

Yes, New Zealand flax, Phormium spp (many varieties sold are hybrids).
