After being totally confused, looking at 3 different sets of rules for Latin, speaking to those who know much more then I and those who have spent time in the region....
I will start the ball rolling with Heliamphora related terminology
List has been pre-editied/proofed and with additional input and comments added from C12 and BB, thanks for the help
el-ON-gata or El-on-gata (which I hear a great deal, especially in the UK)
het-ERO-doxa or HET-ero-doxa (hard "h")
his-PID-a (his-PID-ahh) or (HIS-pid-ahh)
neb-LIN-ae (neb-LIN-eye) or neb-LIN-ee
an-GAS-ima (an-GAS-eye-ma) or an-GAS-eema
TA-tei (TA-tee-eye) or TA-tee-ee (as some in Venezuela say)
Tres Testigos are both tepuis and the name of tiny islands off the coast there. There they pronounce it "TESTI-gos" so far as I can tell . . .
Please add your feedback and additions :-)
