|discussion=<p>Selaginella tortipila, a very distinct species, is probably without close relatives in the flora but may be distantly related to S. rupestris. The two irregularly forked branches are particularly unusual: the larger one forms the strobilus while the smaller becomes arrested and forms either a budlike branch or grows and divides again to form a vegetative shoot.</p>
