I imagine that Frontier has done a fair bit of research themselves on Costa Rican flora, but I just thought it might be interesting to show off the natives I've found (in fact there's a chance that some of these are already in the game, as part of the normal forest).
Drier looking plants (Tropical Dry forest does exist in Costa Rica, though I don't know if any of these are found in it. These plants are all also native to Mexico, though there is Rainforest there too.)
