Some of these are notoriously difficult to identify but I think you are correct. It can help if you can identify the leaf (if it has not been grazed). If we are correct this leaf should have been bark green but more important deeply channelled. Most species are referred to as long ribbed, this one deeply channelled, T. nuda channelled or ribbed and T. brevifolia flat. I will need to look if that covers all your available species.
