3 adjectives to describe palmetto

After a tedious march through a wild country, so overgrown with saw palmetto and underbrush, that our horses had great difficulty to get through it, we arrived at the skirts of the swamp; here a consultation took place between the officers present, and it was arranged that an Indian guide whom we had with us, should go in and hold a parley with the Indians, to induce them if possible, to surrender.
