Iliahi On Oahu, iliahi has these folded skinny leaves that hang. But easiest way to tell is the reddish berry. Although it is valued for its fragrant smell, if you put your nose up to it, there is no smell. I think you have to break the branch to get a smell. Do the Iliahi Loop hike in Pearl City to see this plant.
