During a trek through a small forest-type area on the main island of Hawaii, I came across the following plant:
It did not cover very much area from what I could tell (there was a continuation of the bed just behind me from where I took the picture). I believe it was near Punalu'u Beach but I can't say with certainty.
It's creepy, looks like a tractor load of snakes got loose, and something I find fascinating. Could someone tell me what this cactus-y, bed of vines-like plant is?
