A google for "Anthurium Atlantic Rainforest" brought up one result on Flora do Brasil, Anthurium lacerdae. I couldn't find any images on google images, but went a couple of pages into the web search and found a pdf with some on. It doesn't fit this one but I haven't looked at what else there is. It is terrestrial, and the climbing, branching form is similar to another on the pdf
