plant names and pronunciation!
That's a difficult one since it's all in Latin with also fantasy parts.. A Latin family name, actually a surname that comes first and then a given name that can be anything such as the name from the discoverer with a Latin twist or the region its found or a specific characteristic in the plant.
Since Latin is an ancient and extinct language no longer used as a working language. Even way back in classical history (Roman times) there were no absolute rules and the Latin language was divided into an eastern and western variation. The commoners living in the west region spoke Roman Latin and in the elite in the east spoke Greek (Latin). Then the Latin language migrated further west, the more it got mingled with other languages and regionally changed and it travelled back and forth again. This still reflects in Latin today. The best example for us is probably the Aponogeton. Apon is actually a Celtic word for water or spring and Geiton is Greek for Neighbour. That makes it the plant family that Neighbours the water. Presumably a Latin name in Celtic/Greek language combination
Today it still is divided into Scientific Latin and Roman Catholic Church Latin (Maybe others i don't know about) and there is still some debate among scholars about how to pronounce it correctly.
For example, i met planted tank enthusiasts being educated in church Latin pronouncing plant names differently than the people educated in scientific Latin. Something like the C in Bucephallandra. In church Latin the C behind a U is pronounced as in Butcher, then it is Butchepfallandra. In scientific Latin, the C behind a U is pronounced as an S, makes it Busepfallandra.
One could debate which one is correct, i would say since Botany is science the S would be correct. But somebody educated in church Latin still would pronounce it with the tch. Thus both are correct and there is little to debate.
Then there are certain rules in Accentuation or Emphasis on vowels in between or behind certain consonants. For example when the A,E,I,O,U is short or long. For example i behind the b could sound different than the i behind the L. Or when 2 consonants meet like LL or RR. Or when 2 vowels meet like ii, according to my reference ii = Y as in the English I (do) and not ie-ai as often is pronounced. But can't say if my reference is absolutely correct after all it is still is an extinct language.
It is far too expanded to go into it with details here at the forum. But if you are interested there are sites on Latin grammar to find on the net explaining these rules.
I experienced the pronunciation rules rather very much related to the Spanish and Italian grammar rules.
That could come in handy, to study this and hit 2 birds with 1 stone.
But in the end, it doesn't really matter that much how someone pronounces for example Cryptocoryne Wendtii. I guess i can say Wendt-I or Wendt ie-ai everybody probably knows which one is meant.
