The tree entered and that receiving the druid must be of the same type, living, and of girth at least equal to the druid. Note that if the druid enters a tree, suppose an ash, and wishes to pass north as far us possible (54"), but the only appropriate ash in range is south, the druid will pass to the ash in the south. The Pass Plant spell functions so that the movement takes only one segment (6 seconds) of a round. The druid may, at his or her option, remain within the receiving tree for a maximum of 1 round per level of experience. Otherwise, he or she may step forth immediately. Should no like tree be in range, the druid simply remains within the tree, does not pass elsewhere, and must step forth in the applicable number of rounds. (See Plant Door for effects of chopping or burning such a tree.)
