i dont think its siling labuyo i have a friend who grew it labuyo is not hairy, yours seems to be a little hairy could be a c. preatermissum species, it looks alot like a wild species, it could also be "chunpepe" (PI 406847) a species similar to tabasco, im growing it this year i got the seeds for it from someone from Honduras and its a c. frutescens species the name "chunpepe" is actually the Honduran name for it and is also the crytozoolgical name for a mythological animal from that country, its supposed to be turkey-like
those are my two guesses
sorry if i got a little too deep im good for that now and then
hope this was a little helpful, take this info and check it out against your plant maybe we have a winner!!
thanks your friend Joe
