Well, I've got 2 that match all the criteria (though there are probably more, since it seems to be the norm that important visitors are given a tour of the Orchid Gardens and then have the latest cultivar named after them). However, etiquette demands that someone else gets a go first....

[INJ] I don't know -- I think you asked the vast majority of the key questions in this round (identifying it as a specific named varietal, native to SE Asia, and as an orchid, for example), so I doubt if anyone would begrudge you victory. I'm surprised you found more than one, given all the audience reactions, although I haven't checked the list myself.

[CdM] I agree. I think that INJ should deliver the cut of grass and take the baton. I was persuaded by the audience reaction and your response to INJ's "Imelda Marcos" suggestion that the connection was the Phillipines.

Philippines? No. Don't listen to the audience; they are purposely being obscurantist.

Thank goodness that it wasn't in the 2nd half of the alphabet, or I'd have been forced to try den. Margaret Thatcher!
If this is wrong then it's definitely someone else's turn
