No, I also would not think it is St. Swithin. The sad reality is that unless the seller can give you a list of 'possible plants', it will be near impossible to give it a name with any certainty. It is a lovely NOID, but I am afraid that that is exactly what it is, ... a lovely NOID. (It certainly has philippinense in it, but what else it has will be open to debate, it looks to have at least one other species in its make-up, and perhaps a double dose of phili, but who knows for certain?)
