Papua new guinea tu-lip,

PNG tu-lip - the leves give delicious flavour to stewed dishes, does anyone know what it’s biological name is, or if it can be bought outside PNG?

I think that is Gnetum gnemon. Detailed profile information here: Species Profile for Pacific Island Agroforestry.

I have bought two batches of seed from Ebay or Etsy, for delivery in the US. I purchased the first batch from Singapore, but none have germinated after two years. I bought another batch in December from within the US. They haven’t germinated yet, but I read that it can take up to a year. Some sources say to drill a hole in the hard seed shell before sowing, which I haven’t tried.
