Not tryin' to be a contrarian, just basing this off of Dr. Lebot's book. He says on Pentecost Island "Borogu is called Borogoru in the north of the island and Gorogoro in the south." He breaks down similar plants even further, saying there is one called Borogu Temit(light) which is identical looking to Borogu but with
lighter stems and an effect closer to Borogoru. In the north it's called Borogoru Maita and in the south it's called Gorogoro Entepal. Another is called Borogu Tememe(red) which has the appearance of Borogu but with red/violet stems. This one has a stronger psychoactive effect than Borogoru Temit. (
sounds awesome) It's referred to as Borogoru Memea in the north and Gorogoro Entemet in the south.
...elsewhere, he does mention another 'Borogoru' from Maewo Island that has more DHM than Pentecost's Borogu.
But, who's to say what happens to the names over time as these plants travel to different islands and villages. I have no 1st hand experience with any of it, just reading.
