I hadn't thought about the two above being phonetically written. Figured they were probably just different spellings/languages of tea. Thank you for that.
Re. 1619, I don't think it can be collection year, because it's supposed to be collected in 1691 by Engelbert Kaempfer, who was born in 1651. When I google "R.H. 1619" the only other relevant reference is in this passage here, also related to tea, but that doesn't help me much in finding out what that reference means. I could wager a guess that H. is either "Hortus" or "Herbarium". Does this seem likely?
This is the specimen in question by the way, which has collection year and such, and information that it was Johann Amman who wrote R. H. 1619.
Oh... Could 1619 simply be a mistake in writing 1691? Just occurred to me. Though that doesn't explain R. H.
Sorry for many edits.
