Morinda citrifolia is also known as Noni or Indian Mulberry. The flowers generally have 5 lobes, but this can vary, as this plant shows. The flowers emerge from what will become the fruit, which will end up white or yellowish.
The fruit is edible and used for medicinal purposes, but usually in a juiced form. There’s a good reason for this. As is noted on Wildlife of Hawaii’s plant page, “The ripe, white fruit has a nauseatingly bad smell, very much like fresh vomit mixed with rancid garbage. Avoid smelling it if you have a weak stomach.” Duly noted!
This plant was next to one of the Golden Ponds of Keawaiki.
