Hey, I think you arlready have the type of species, its a serissa foetida, which is the small leaved species, they have extremely sensitive roots, and they are very hard to repot and still being able to ensure its survival. Not quite sure what you mean by threading, do you mean the wire? If so, you can check it yourself, if the wire seems to be biting a bit into the bark then it should come off. Nice purchase by the way, it has some great taper, If it where mine I would think out the foliage and wire the foliage pads so you can see more of the trunk.
