I concur with Coeruleo that this hybrid could have originated from Thailand .......Lc Netrasiri Fireball is a well-known stud plant in Thailand and I have the 'Napporn' clone shown by Jenn. There is also a Potinara Thitti, which I'm not familiar with and the clonal name could be ' Kasem's Choice' as in Kasem Boonchu, a very well-known Thai breeder.

As to 'porn' the Thai pronunciation is different from your 'porn' as in smut, but pronounced with plosive 'p' and sounds something between 'on' and 'own'.
