Jungle?

[Hai-Etlik]

That rather depends on the rest of your symbology. Consider if the distinction between jungles and other kinds of forests is important; if so, what about other distinctions between forests like temperate and boreal/taiga?

Take a look at this map I made of Britannia from the Ultima games.



I represented forests as collections of tree symbols, and for jungle I just took the broadleaf tree symbol and mixed it with palm trees. There's a little down in the southwest.
