Camellia sinensis is called laphet and miang in two southeast Asian languages, but in almost every other language, its name derives from, broadly, one of three similar etymologies. (All three etymological lineages have resulted in a related English word.)
Which of the three pan-linguistic names for the species comes to English likely via Hindi and Persian? This was the same name (same spelling, at least) that Giovanni Battista Ramusio used in 1559, publishing the first reference to this species in Europe.
